revclstoner Posted March 23, 2019 Report Share Posted March 23, 2019 Hello, everyone! Hope that all is well. I have a question in reference to GMRS channels 8-14. I do understand that, in terms of wattage, one can transmit at ½ watt; however, I’ve read (on two other sites) that one can transmit at much more power (at least 5 W), if you’re using a programmable part 95 (or part 90) radio. Is that so? I do own a part 95 radio that can transmit at 1 W low power and 4 W high power. Thanks for your time! Quote Link to comment Share on other sites More sharing options...
marcspaz Posted March 23, 2019 Report Share Posted March 23, 2019 - On channels 1-7, the power is limited to 2 watts under FRS rules and 5 watts under GMRS rules. - On channels 8-14, the maximum power is 500mw, regardless if you are operating under FRS rules or GMRS rules. - On channels 15-22, the power is limited to 2 watts under FRS rules and 50 watts under GMRS rules. If your radio doesn't drop to 500mw ERP, I wouldn't recommend using it on those frequencies. "§95.567 FRS transmit power.Each FRS transmitter type must be designed such that the effective radiated power (ERP) on channels 8 through 14 does not exceed 0.5 Watts and the ERP on channels 1 through 7 and 15 through 22 does not exceed 2.0 Watts." Also... "§95.1767 GMRS transmitting power limits.This section contains transmitting power limits for GMRS stations. The maximum transmitting power depends on which channels are being used and the type of station.(a) 462/467 MHz main channels. The limits in this paragraph apply to stations transmitting on any of the 462 MHz main channels or any of the 467 MHz main channels. Each GMRS transmitter type must be capable of operating within the allowable power range. GMRS licensees are responsible for ensuring that their GMRS stations operate in compliance with these limits.(1) The transmitter output power of mobile, repeater and base stations must not exceed 50 Watts.(2) The transmitter output power of fixed stations must not exceed 15 Watts.( 3 ) 462 MHz interstitial channels. The effective radiated power (ERP) of mobile, hand-held portable and base stations transmitting on the 462 MHz interstitial channels must not exceed 5 Watts.© 467 MHz interstitial channels. The effective radiated power (ERP) of hand-held portable units transmitting on the 467 MHz interstitial channels must not exceed 0.5 Watt. Each GMRS transmitter type capable of transmitting on these channels must be designed such that the ERP does not exceed 0.5 Watt." revclstoner 1 Quote Link to comment Share on other sites More sharing options...

revclstoner Posted March 24, 2019 Author Report Share Posted March 24, 2019 Thank you all for clarifying this for me! I'll leave those frequencies out of my radio since the lowest it can transmit is 1 W. You all are appreciated! Logan5 1 Quote Link to comment Share on other sites More sharing options...
