TELECOMMUNICATIONS CERTIFICATION BODY (TCB's):

1. Why did the FCC start the "Permit but Ask"? They wanted to monitor certain devices that were being approved by TCB's. The FCC has stopped monitoring the 15.239 devices as of 8/15/2007. 
2. How long does it take if we submit something that is on the "Permit but ask list"? There does not seem to be any limit on time. so far the longest that we have experienced is 60 days. 
3. When did the FCC begin to authorize TCB's? June 2, 2000.
4. Will the FCC stop issuing Equipment Approvals? No, they have not said that they will stop.
5. Can a manufacturer become a TCB? No
6. Can a TCB approve all of the devices that the FCC can approve? NO! Devices below 300MHz and above 3000MHz that reqwuire SAR testing must be submitted to the FCC. Or you can send us an email & ask us.
7. Can TELEPHONES be approved by TCB's? Yes if it is within their SCOPE. 
8. Is a TCB approval the same as an approval from the FCC? Legally it is, the TCB grants are issued from the FCC's computer by special authorization to the TCB. 
9. Where can I get a list of devices that a TCB can approve? Send email to info@timcoengr.com. 
10. Can a TCB approve a "Change in FCC ID" application for a 900 MHz DSSS Cordless Telephone?  Yes, If the telephone has already shown compliance with the radiation exposure requirements, a TCB may process a change in ID.  Otherwise a TCB can not.
11. Can a TCB dismiss a Grant? Yes, within the first 30 days and the FCC identifier can be reused. 
12. Can a TCB issue a Grantee code? NO, The FCC is the only one that can do this, but the TCB CAN handle it on behalf of the applicant. 
13. What would happen if you send an application to the TCB and we find a discrepancy in the test report?  When we discover the discrepancy, you will be advised by e-mail and/or phone after a complete review of the application has been done.  A resolution of the discrepancy is required within 30 days of the initial request.  There is no additional fee for this.
14. Can a TCB approve a Class II change? Yes. 
15. 18.301 Consumer Lighting device, Do I have to make Radiated emissions? And if yes then what is the range of the measurements? Yes radiated emissions must be made per 18.305 and the range of measurements are spelled out in 18.309. 
16. Can a TCB make Exhibits Confidential for an application that I submitted directly to the FCC some time ago?  Yes, but this must be done by a Class II Permissive Change application. 
17. Can a TCB approve an application for a device which is to only be professionally installed?  YES.
18. Medical diathermy Equipment: What is the requirement? According to 15.103e medical equipment is exempt from all requirements of FCC Approval. 

GENERAL:

1. Where can I view the FCC Rules ONLINE?  Click Here for FCC Rules Online.
2. How can I get caught if I do not get FCC approval? And what would happen if I did? There are several way to get caught, by your advertising. Your competitors. If you import the device , by customs. We're not lawyers but you could be fined up to $2000/day. Check it out at   http://www.fcc.gov/ 
3. Labeling, where can I find the rule part on labeling of an unlicensed device? FCC Rules 15.19, and Rule part number 2.924, 2.925 & 2.926 are important. 
4. As a manufacturer, can I change the model number or brand name without changing the FCC identifier? Yes, as long as the unit is properly labeled including the FCC ID.
5. What is a permissive change? There are 2 types of permissive changes;     a. Class I change is a change that does NOT effect the EUT's performance or the test results that were submitted to the FCC with the original Approval. b. Class II permissive change is a change that effects the performance of the EUT and the test data that was submitted with the original approval. For a Class II change the EUT must be tested and the test report submitted to the FCC or a TCB for approval before the change can be put into production. 
6. Where can I find this in the FCC Rules?  You can't, this was set by policy. 
7. Do all electronics that are shipped to Europe have to have the CE MARK? Yes, it is the responsibility of the manufacturer to insure that their products meet all of the directives, EMCD, R&TTE D & SAFETY. 
8. Where can I get a copy of the new R&TTE DIRECTIVE? The R&TTE Directive is available in this web site.  Click on "Downloads" at the tool bar on the left, or any page.
9. Does a Cable Modem need Part 68 approval? No, since it does not connect to the PSTN it is not necessary. 
10. What is considered a Product or a Module? A product must have a case enclosing it, otherwise it is a module. 
11. Does a Part 90 face-held/body-worn UHF PTT radio with an output power of 4.5 Watts require SAR testing?  YES, The FCC responds: "Routine SAR evaluation is required for Part 90 SMR transmitters, as indicated in 2.1093 of FCC rules.  For other portable Part 90 transmitters, we are reviewing the operating configurations and exposure conditions, including applicable source-based time-averaging factors and body-worn conditions, to make case-by-case determination on if SAR may need to be requested according 1.1307(d)."  
12. My device is to be mounted on a wall or similar surface, thus concealing the equipment label.  Can I do this?  Yes, as long as the label is readily visible to the purchaser at the time of purchase but not necessarily as installed.
13. Can a manufacturer outside the United States prepare a Verification Report or Declaration of Conformity (DoC) based on the data collected by another test lab?  No.  Verification must be issued by the test laboratory that performed the testing.  A DoC cannot be issued by a third party.  The DoC must be issued by a properly accredited and designated facility as authorized by the FCC under the appropriate Mutual Recognition Agreement (MRA).
14. FCC interpretation database https://fjallfoss.fcc.gov/oetcf/kdb/  
15. Declaration of Conformity (DOC): Am I required to put a copy of the DOC on my equipment in the USER Manual? Yes you must include a copy in the User Manual or insert it on a separate sheet. 
16. Q: Composite devices; DOC and Certification: If a composite device is subject to both Certification and Declaration of Conformity (DoC) approval procedures, does the DoC compliance information have to be submitted with the Certification filing?
    A: Composite devices or systems operating under the provisions in Part 15 are subject to the approval requirements in 47 CFR 15.31(k). If a composite device is subject to both Certification and DoC approval, the Certification filing should indicate that the device will also be DoC approved. The exhibits for the label in the Certification filing should show compliance with the Certification labeling requirements and the DoC labeling requirements. Additional DoC requirements, such as the compliance information in 47 CFR 2.1077, are normally not required, but may be requested at anytime by the FCC or a TCB.
    
17. Q: If a device that was issued a Grant of Notification is still being manufactured and marketed, can the manufacturer replace the FCC ID with the FCC Logo that is used with a product that was approved under the Doc process?
    A: In order to replace the notified products FCCID label with an FCC logo, the device should be retested to verify compliance with the current regulations.
    

PART 15 UN-INTENTIONAL RADIATORS:

1. If I have an INFRARED DEVICE does it require FCC approval? No, if it is only an infrared device. But if the device has a computing device in it  that has a clock frequency greater than 9KHz, then  it must be tested for FCC compliance under 15.109.   
2. I have a 300MHz SECURITY RECEIVER and I heard a rumor that I no longer need to get approval. Is this true? No, You must have this receiver tested by an accredited test laboratory and get a DECLARATION OF CONFORMITY for the unit or get a Certification for it. 
3. Under the NEW revised rules do SCANNING RECEIVERS still have to be CERTIFIED? YES, the approval status of scanning receivers has not changed as of 9/10/98. 15.109.
4. What frequencies are SCANNING RECEIVERS allowed to receive on?   Scanning receivers are allowed to receive on all frequencies except the cellular frequencies which are 824-851MHz and 869-896 MHz..  There must be no way for an "end-user" to modify the receiver to receive on those prohibited bands.
5. Will the firmware in my microprocessor meet the prohibitions for a scanning receiver in the cellular bands? The FCC specifically noted in paragraph 19 of the Report and Order that use of a masked ROM would satisfy the prevention of scanner modifications provided the microprocessor containing the masked ROM is permanently affixed to the circuit board.
6. Does an AMATEUR SCANNING RECEIVER  that is part of a transceiver that scans only the amateur bands have to meet the 15.121 requirements?  No, the amateur radio service is considered a licensed service, therefore, a receiver used for receiving only amateur frequencies is part of a licensed station. As such, it does not meet the definition of a scanning receiver and doesn't have to comply with section 15.121.
7. What if the SCANNING RECEIVER is the same as #5 above but also has the weather band?  Adding a weather band to the above makes this device a scanning receiver subject to Section 15.121, if it can receive two frequencies outside the amateur service.
8. What is the definition of a SCANNING RECEIVER?  The new definition of a scanning receiver states that a scanning receiver is a receiver that "automatically switches between two or more frequencies in the range of 30-960 MHz and that is capable of stopping at and receiving a radio signal detected on a frequency.
9. Do JOYSTICKS require and equipment approval?  Would it be subject to DoC or Certified?  As stated in Section 15.103(g), joystick controllers that do not contain digital circuitry are not subject to the technical standard or the equipment authorization requirements.  They are exempt and subject only to the general operational requirements stated in15.5 and 15.29.  If, however, digital circuitry is utilized, the applicable authorization procedure would be either DoC or Certification.
10. If a CCTV Monitor has a built-in receiver and that receiver is tested and approved under DoC rules, does the CCTV Monitor have to be tested and verified as well?  Yes, but that testing can be done as part of the DoC testing on the receiver portion of the device so no additional testing burden is applied to the device.
11. Wireless KEYBOARD, MOUSE, & RECEIVER: Can I get approval for the 27MHz Wireless Keyboard, Mouse, & Receiver approved under a single FCCID? No! The Keyboard & Mouse can be approved under a single FCCID if they are in the same case, but if they are in separate cases then they must have separate FCC Identifiers. The 27MHz receiver only has to be approved as a CPU Peripheral and can be done by either DOC or Certification, but if certified then it must have a unique FCCID. 
12. Wireless KEYBOARD, MOUSE, & RECEIVER: Can I get approval for the 49MHz Wireless Keyboard, Mouse, & Receiver approved under a single FCCID? No! The Keyboard & Mouse can be approved under a single FCCID if they are in the same case, but if they are in separate cases then they must have separate FCC Identifiers. The 49MHz receiver would have be tested & approved as a receiver & CPU Peripheral and can be done by either DOC or Certification, but if certified then it must have a unique FCCID. 

PART 15 INTENTIONAL RADIATORS(UNLICENSED):

1. 27MHz: Can I use any other antenna below 30MHz other than a LOOP antenna? the FCC says NO! Please see Section 4.1.5.1 of ANSI C63.4-2003. 
2. 2400-2483.5MHz Band: Can a manufacturer use the same chip set for a wireless product for both the USA & EU if they supply the software to set the channels with the product? NO, because the EU allows operation on the channels above channel 11 which would cause the product to be in non-compliance at the bandedge of 2483.5MHz, 
3. Is a RF Exposure Warning statement required for all intentional radiators? RF Exposures Warning statements are generally required in USER MANUALS for any intentional that must be tested for SAR.  All Part 15 devices that are specified in field strength do not require a RF Exposure Warning statement. 
4. What qualifies as a "UNIQUE" connector under 15.203? For Part 15 Products it is best to check with the FCC for any connector.  Here is a partial list of acceptable connectors; MMCX, MCX, U.FL and reverse polarity SMA, BNC, TYPE N & TNC.
5. What is the biggest problem with toy WALKIE TALKIES in passing the FCC requirements? Passing the radiated emissions 15.227 & 15.235

7. I am buying a spread spectrum PCMCIA CARD that was originally approved by the manufacturer, can I get an approval in my company name? Yes by either retesting and filing an application or by getting permission from the original maker to allow you to reference their original report. (15.247)
8. With reference to the above question, once I have my own approval of this module, can I install it into any of my products without any other approval? If the device that you install it into is a computing device then you must test that device as a digital device, if not then you do not have to get any other approvals. 
9. Can I use a CAR ALARM TRANSMITTER for a Radio Controlled toy that I am designing? NO, Toys are not allowed under 15.231. The only frequencies that a RC toy can use is 26.96-27.28MHz, 49.82-49.90MHz, & 902-928MHz.
10. I want to get my spread spectrum product approved with more than one antenna, is this possible? Yes, but you must test each antenna that you want approved.
11. Where in the rules does it state that the antenna on a Part 15 device must be PERMANENTLY attached? 15.203 
12. What frequency can I use for voice?  Please click for link to "long-winded" explanation to this one !
13. Is a carrier current device verified or certified?  Verified.  Either intentional or unintentional devices must be tested at 3 locations: 1) test facility  2) manufacturers facility  3) typical frame house.
14. Can I use a standard connector on my intentional radiator?   NO in most cases, but Yes if it is professionally installed.  To meet the definition of professionally installed, it must meet three requirements.  1)The connector cannot be sold retail, to the general public or by mail order. Making it only available to dealers.  2) Requires professional installation by licensed professionals with special training.  3) The intended use is not for general public - for industrial/commercial use.
15. For a manually operated transmitter, what is the maximum length of transmission?  15.231(a)(1) says 5 seconds, then it must automatically deactivate.

17. 15.231(a) Can I design a wireless mouse to operate on 422.3MHz under this section of the rules? Yes! Under the revised rules you can send data, but not supposed to be continuous & must be preceded by a control signal. 
18. 15.209 Can I have a wireless mouse operating on 422.3MHz operating on this frequency? Yes under 15.209 you can have it operating on any frequency you want to as long as it meets the requirements of this paragraph of the FCC Rules & is not in a restricted band.  
19. Are there any other frequencies that I can use for a wireless mouse? Yes, you can use 26.96-27.26MHz or 49.82-49.90MHz & 902-928MHz. 
20. 15.249: In the 902-928MHz band, can I average the field strength measurement? No, you either must measure in peak or quasi-peak . 
21. Part 80: Can I transmit on channels 75 and 76?  No, FCC Rules Part 80.871 designates these channels as "Guard Band".  These channels are on either side of channel 16: 156.8 MHz.
22. 15.249: I have a cordless telephone that the HS transmits on 2.4GHz band and the Base transmits in the 902MHz band. Can I have the same FCCID on both the HS & the Base? NO! they must have seperate FCCID's. When the FCC originally allowed the same FCCID on both the HS & the Base it was assumed that they both would operate in the same frequency band.
23. SAR: Where can I find the FCC requirements for RF Exposure? CFR 47 Part 1 Subpart I para 1.1307. We have a calculator on the secure part of our web site that you can use to determine if SAR is required. 
24. 15.245: 10,500-10,550MHz Radar Guns. Part 15.245 says it is for only field disturbance sensors, but I see that the FCC has approved radar guns under this rule part, is this correct? Yes since the FCC has set the presendent one has to assume that a radar gun is a Field Disturbance sensor. 
25. External Amplifier: Can I get approval of my 2.4GHz amplifier? Yes & No. Read 15.204 (April 23, 2004 Edition). The external amplifier can be approved as part of a system but not as a stand alone device. 
26. Does the FCC require that a Bluetooth Device comply with anything other than the FCC Rules 15.247? No, The Bluetooth device only has to meet the FCC Rules 15.247. The FCC does not care if it meet the Bluetooth Protocall.

3. Can I sell my product without FCC approval? No, if you are caught selling this product without approval, you will be subject to heavy fines by the FCC.  You are not allowed to import goods unless they are FCC approved. You can view The FCC's web http://www.fcc.gov/  
4. Can I get my transmitter that covers the frequency range of 300-390MHz approved? No, there is a restricted band 322-335 MHz.  You can get approved in 300-322 MHz or 335.4 - 390 MHz.
5. Can I use the security frequency for Voice?   No, continuous transmission such as voice or video and data transmission are not permitted.
6. I have a pendant transmitter that has been approved in the 315 MHz band.  I am going to produce two additional products, a smoke alarm and a handheld, whose schematics will be identical, but will have different PCB layouts because of the size of the product which will contain them.  Can these two additional transmitters be filed under the same FCC ID or must they be different?  No, the two new transmitters are different from the original and from each other.  Even though the schematic diagrams are identical, they are different products.  They will require approval under separate FCC Identifiers, different from the original.
7. Can I use this section of the rules, 15.231(a), for a toy? No! Toys are prohibited. 
8. Can I use 15.231(a) to transmit data, like for a thermometer ? YES! 15.231(a) has been changed to allow the transmission of live data, however you cannot transmit data continuously. 
9. I have a cusotmer that has a remote control (433.92 MHz) approved under FCC rules 15.231.  The have just completed printing many labels and their product has already been on the market.  They wish to increase the output power - which we have advised them that they cannot do as a Class II Permissive change.  They have asked if they can request their grant of certification to be dismissed and reapply with the product with the higher output power under the same FCC Identifier.  We would treat it as an original filing.  Is this permitted? The FCC cannot dismiss the original grant because your customer has already sold products under this grnat in the market place. Your customer can apply for a new FCC ID number based on the Rule Part 2.933. This is the only option to get a new  FCC ID because your customer can't do a Class II Permissive Change since they are increasing the power.

ACTA TIA/EIA/IS-968 & ACTA TIA/EIA/IS-883 (PART 68) - TELEPHONE PRODUCTS:

1. How do I get a waiver with this new Part 68 system? Under the new system with ACTA a waiver is no longer required.

2. What earth balance requirements apply for ADSL-TE? Probably the longitudinal voltage and transverse balance requirements in TIA/EIA/IS-968 .You will need to contact ATIS at acta@atis.org or TIA's Committee TR41.9 or ATIS Committee T1E1 for details. The FCC does not interpret or explain the rules adopted by ACTA.
3. Where can we obtain information on the new registration number format? Contact us or The new registration number format is presented in TIA/EIA/TSB-168, Telecommunications - Telephone Terminal Equipment - Labeling Requirements, June 2001.
4.  Do I have to do any testing under the new system, can't I just issue a SDoC? No you must have your telephone device tested & you must register the SDoC with ACTA. 
5.  I have a TELEPHONE that requires Part 68/ACTA registration.  What do I need to do and how long will it take to get a registration number? We need 1 sample and the necessary paperwork in order to test the product and submit an application to the FCC.  It takes the FCC approximately 30 days to issue a registration number - once this number is issued you must affix it to your telephone product and then you can import it.
6. What if I have several different manufacturing locations for a TELEPHONE - can I use the same registration number? NO, the FCC will issue a different registration number for each manufacturing location. You must submit a re-registration application anytime you change a manufacturing location.
7. Must I have a sample tested every six months and submit a new application to the FCC for an already approved  telephone? You must have a current production sample of the telephone sample tested at least once a year to confirm that it continues to comply with the Part 68 requirements but you do not have to submit a new application to the FCC.  If you have made modifications to the device, it will be determined during the annual continuing compliance testing whether you must submit a modification application to the FCC or not.  If not, a report will be issued to you, the applicant, listing the modifications, and it will contain current data showing the unit as meeting the requirements.
8. HAC/VC Telephone Requirements.
9. ADSL: Can ADSL2 and ADSL2+ devices be certified by ACTA to be sold on the U.S. market?  No, ACTA has not adopted a standard for these new devices. ADSL2 and ADSL2+ do not meet the present TIA-968-A Transverse Balance Limitations.

If you want to read all about download FCC-04-292A1 Extension (you can download this from our website). 
3. Part 90: I have an approved Transceiver in the bands 150-174 & 421-512MHz with 12.5kHz & 25kHz voice channels how long can I sell it with out having to meet the 6.25kHz BW per voice channel? At this time there is no cutoff. 
4. Part 90: Is a Licensed Transmitter required to have a UNIQUE CONNECTOR? No, a unique connector is not required for any licensed device. 
5. Is a combination FRS/MURS radio legal?  NO, the FCC will not permit a single radio to combine both the MURS and FRS frequencies.
6. FRS/GMRS: What is the highest output power permitted for a FRS/GMRS combination transceiver?  GMRS units are permitted up to 5 Watts output power, so a combined unit can have 5 Watts on the GMRS frequencies and the FRS frequencies can have up to 0.5 Watts. 
7. FRS/GMRS: Can a single radio be approved for both FRS & GMRS services? YES, see FCCID: AZ489FT4850, AS as long as the radio meets the requirements of both services. 
8. GMRS: Can any type modulation other than voice be used on  GMRS radio? NO, see 95.631 and 95.181(a) & (g).
9. GMRS/FRS/Pt90: I want to make a Class II change to my licensed radio & I know that I will have to re-test the EUT but after I get the Class II approved I want to sell both versions. Can I do that? Yes, but when you file the Class II change you need to indicate that you are going to do that and provide a detail description of the changes in the letter to the FCC/TCB describing the changes. 
10. What type of application is required for a CB TRANSCEIVER? A type acceptance filing must be done on the transmitter portion of the device and a certification filing must be done on the receiver portion.
11. Why is a FAMILY RADIO SERVICES unit Certified? Because it is an unlicensed device. Although the requirements for this device is in Part 95 of the FCC rules it is certified.
12. Do all DATA TRANSMITTERS have to meet the requirements of Part 90.203(j)(3)? Yes, except AFSK units where the tones are fed through the microphone connector.
13. Do Data TRANSMITTERS under 0.5Watts have to meet the requirements of 90.203(j)(3)(data spectrum efficiency)? NO, but they have to meet all of the other requirements including Transient Frequency Response.
14. I have a 25KHz channel radio that was approved before the channel splitting, can I file a Class II change and get this radio approved for 12.5KHz channels? YES, if the original unit as the capability to satisfy the technical requirements for the 12.5KHz operation. Please note that the unit is not to be modified to meet these requirements. It must inherently meet the requirements. If modification is required then the FCC Identifier must change and a new type acceptance must be filed for a new approval.
15. 90.217:  I want to get approval on a 120milliWatt transmitter under this section of the rules, does it require any testing? YES, although it says it is exempt you must still meet the requirements in section 2.1033 (c)  of the Commission's Rules & Regulations. This is just about everything that is normally required for Type Acceptance, although the requirements under Part 2.983 are not a difficult as in Part 90. Also you do not have to meet any 90.203(j)(3) or 90.214. 
16. I have a type accepted transmitter that I want to put into another case, do I have to retest and get a new type acceptance? If the PCB & the SCHEMATIC have NOT  changed then you do not have to do any additional testing but you must file an application with FCC for approval of this new model. If the SCHEMATIC stayed the same and the PCB layout changed then you will have to have the radiated emissions re-measured and a report filed with the FCC. Also if the original approval is over 2 years old then there is a possibility that the FCC will ask you to retest it.
17. 90.203(j)(3) Is it true that there is a minimum data rate for a data transmitter? Yes, Part 90.203 says that the minimum data rate is 4800 Bits per second for each 6.25KHz of bandwidth.
18. 90.203(j)(4). When does the 6.25kHz channel bandwidth become a requirement? Jan. 1, 2005 except for HH's portables under 20.W O/P.
19. I want to change the Power output on my TRANSMITTER, can I do that by a Permissive Change? NO! The only way the RF power output can be changed is to re-file an application with a different FCC identifier.
20. What is the frequency stability requirement for a FRS? +/- 2.5ppm over temp range of -20 degrees C to +50 degrees C.
21. What is the frequency stability for other rules parts? It depend on the service, you must check the applicable rules, but the temperature range is -30 degrees to +50degrees C. 
22. Can I include a weather band receiver on my FAMILY RADIO SERVICES (FRS) Transceiver?  Yes, it is allowed.
23. On a type accepted transceiver, if I change output power, can I submit a modification application?  NO, as per FCC Pt 2.1043 any changes to the power output level are not considered permissive and therefore require a new FCC ID.
24. RF Power/Class II: I am measuring a EUT for a Class II change, does the RF Power Output have to be exactly the same as was approved on the original Grant? No the FCC has said that they will allow a tolerance of +,-0.5dB on conducted measurements and +,- 3.0dB on ERP or EIRP measurements, however the power on the grant will not change.
25. With Reference to the above Question, If I am doing a Class II change on a EUT that had SAR testing on it originally, do I have to retest the SAR if I make a change? Yes you must retest the EUT for SAR. The EUT must meet the requirements with these changes.  
26. I have a Pt 90 Transceiver that is approved. What do I have to do to change trade name and model number?  You CANNOT change the FCC Identifier, but on the new label you can change Trade Name and Model number without notifying the FCC.
27. Do I have to use the substitution method(EIA/TIA Standard 603-1992) to measure the radiated emissions on a licensed transmitter? Yes, If you want the detailed explanation send us email. 
28. 74.801: What audio frequency range is required to be tested for a wireless microphone? It must be tested from its lowest frequency to at least 15kHz, we recommend 100-15kHz. 
29. 74.801: If I do occupied bandwidth at 15kHz modulating frequency is this enough? No, you need to do it at the peak frequency of the audio response & 15kHz. 
30. 74.801: Are wireless microphones required to have a modulation limiter? No but you must prove that the EUT's deviation will not exceed the 75kHz. 
31. MURS: Is MURS(Multi User Radio Service) this a licensed service? NO, Part 95 Subpart J, see Report & Order FCC 002-235 released July 12, 2000. You can download from our website. 
32. MURS: What are the MURS Frequencies? 151.820, 151.880, 151.940, 154.570, & 154.600MHz
33. Part 90: If I supply the antenna with my portable transceiver can I have the power output on the Grant listed in ERP?  No, The FCC does not list ERP on the Grant (line entry) unless the unit has a built-in antenna.  We will list the antenna terminal / conducted power output.  We can put a comment on the bottom of the Grant saying that the power output listed is conducted and that the ERP is XXX with the supplied antenna.

34. Is it still necessary to measure frequency stability as a fuction of temperature for S & X-band radars? Frequency stability as a function of temperature is still required under Part 80.209.  The limit for the S-band is 5ppm, and section 80.209 b would apply in the X band for pulsed modulation.  Depending on the radar use, Part 80.211: authorized BW and Part 80.375: allowed freq., may be used to determine compliance with the Part 80.209.  

35. 97.317(a)(3) States that any linear amplifier must be driven with 50Watts, is this correct? YES, the FCC has continuously re-confirmed this requirement.

36. 95 Subpart C: R/C Devices: Does a 26-27MHz RC device have to be Certified or Verified? Verified according to 95.603 (b).

37. Can a remote control transmitter under Part 95 of the Rules have a user-replaceable crystal?  No.  FCC Rules section 95.645(b) states: “An R/C transmitter which incorporates plug-in frequency determining modules which are changed by the user must be certificated with the modules.  Each module must contain all of the frequency determining circuitry including the oscillator.  Plug-in crystals are not considered modules and must not be accessible to the user.”

38. 95 Subpart A: GMRS Devices: Where can I find the requirements for the low pass audio filter (post limiter filter)? 95.637, has the information, 60logf/3 between 3 & 20kHz.

39. 90.210: This rule part talks about with & without a post limiter, where can I find the requirement for the post limiter filter? You cannot find any requirement for this, only the reference in 2.1047. 

40. GMRS, Part 95: Can I have an external antenna connector on a GMRS radio? Yes. 

41. MURS, Part 95: Can I have an external antenna connector on a MURS radio? Yes. 

42. FRS, Part 95: Can I have an external antenna connector on a FRS radio? NO!. 

43. MURS/Part 90: What are the requirements for a transmitter previously certified under Part 90 to be reauthorized under the MURS Part 95? The transmitteralready meets the MURS power limits so that it does not require modification of circuitry for MURS use. Does a new application for certification and technical information have to be submitted? Answer: The manufacturer may file an application for a Class II permissive change per Part 2.1043 to change an existing grant of certification. The filing must be accompanied with a clear statement of the requested change and the reason for the change. In addition , the filing should include necessary test data or other technical information to show continued compliance of the transmitter, For MURS equipment operating under Part 95 - Subpart J, the existing filing may not need additional technical information, if the technical requirements are no higher than those for Part 90 transmitter. 

44.  

FAMILY RADIO SERVICES (FRS):

1. Can I have a VOX on my FRS unit? Yes
2. What is the temperature range for the frequency stability and the frequency stability for a FRS? The stability is +,-2.5ppm and the temperature range is -20 to +50 Degrees C.
3. IC: Can I get my FRS radio approved in Canada? Yes as of 3/27/00. 
4. IC: Is it true that I must get my FRS radio test for SAR? Yes if you want it rated for 500mW. No if you have 400mW with a 50% duty cycle. 
5. Can a FRS be a mobile unit? Yes but the RF portion of the Transmitter must an integral part of the antenna. 
6. Can I make a combination FRS/GMRS transceiver? YES!   
7. Can I use "data" on my FRS unit?  No, per paragraph 95.631(d) only voice may be used.
8. FRS: Can I design a baby monitor system using a VOX ? The Family Radio Services is a TWO-WAY radio service and the FCC says that a baby monitor does not qualify. 
9. FRS: Can I transmitt data on the FRS freqwuencies. No, 95.193 & 95.631(d), says only live voice. 95.631(d) says only F3E emission.  

 COMPUTERS:

1. My computing device  only has a 1.0MHz clock, do I have to have it tested? Yes, anything with a clock frequency of greater than 9KHz  must be tested for compliance under FCC  15.109
2. Can a TCB issue a certification on a COMPUTER? Yes, if it meets the requirements. 
3. JOY STICKS: Do Joy Sticks have to be approved? If they have digital circuitry with a clock frequency that is higher than 9kHz then YES,  but other wise NO.
