They don't and primarily it has to do with specific absorption rate. https://en.wikipedia.org/wiki/Specific_absorption_rate The labs that certify this gear must ensure that your body does not get heated above a certain level when RF device is operated nearby. You might see a 6 watt VHF radio, but that is pretty much the limit. an example cert. https://fccid.io/AZ489FT7087/RF-Exposure-Info/SAR-Report-1-of-2-3054950

Well, I think you get heated more from sun exposure than by 25w VHF/UHF RF exposure... we are exposed to so much RF that a few extra watts here and there I don't think is going to make much of a difference in the long run... G.

It is agreed that the information is readily available if one has the callsign. I use the ULS directly and frequently. I must admit I have on multiple occasions just wanted to know what city a particular poster was on in by looking up their profile via the post. At least in TapaTalk, the app I use for MyGRMS, the city and state does not appear there. I wish it did. Michael Sent from my iPad using Tapatalk

The ULS system the FCC uses for LMR license data can do searches in geographical areas. All you need to do is enter the parameters you want; ZA for the license type and state to return a list of all license holders within the state. You can drill down even further getting those in a county or even city if desired. Yes, the feature of searching the FCC database could be programmed into MyGMRs if Rich wanted to take the effort but its also just as easy to go directly to the FCC and pull the data yourself.

That is an excellent point regarding potential saturation of some components. It is a certainty that there will be some specific conditions where the presence of a static magnetic field in the presence of some equipment and components will have negative consequences and many where it will not. It comes down to the circuit, the components used, intensity of the field and degree of shielding among other factors. Sounds like a great research project for one of our readers aspiring to get their PhD. Best regards, Michael WRHS965 KE8PLM Sent from my iPad using Tapatalk

BINGO!!!!! BINGO!!!!! BINGO!!!!! It is not the FCC GMRS specifications (at least as currently written) that explicitly limits the output power of a hand-held transceiver across the board. Max overall power for the handheld is ultimately limited by the ability of the transceiver-antenna system to achieve SAR compliance on the frequencies of operation. For those reading this post that do not already know this, amateur radio operators are required to know how to calculate or have the ability to measure this for equipment they own and operate. They are legally required to make sure that safe SAR levels are maintained, which applies to family and the public. Kudos WPXM352! Michael WRHS965 KE8PLM Sent from my iPad using Tapatalk

Logbooks on GMRS? Nonsense, my friend. Logbooks on Ham band? Whatever blows your skirt, it's a free country.
