You may have noted from the list of frequencies above, that GMRS and FRS share seven simplex channels. A simplex channel is one where the transmit and receiver frequencies are the same. For those of us who are not ham radio operators, this is pretty much what we are used to, and how ...
Most 22 channel radios of this type which were formerly marketed as GMRS/FRS combination radios (radios that are not capable of repeater operation, do not include the repeater input frequencies, have a maximum power of 2 watts and have a non-detachable antenna) have been reclassified as FRS ...
it’s illegal to use GMRS channels 19 and 21 north of the 49th parallel from Washington to Minnesota, and other points sufficiently near the Canadian border (apparently they conflict with some Canadian military frequencies.) The thing that always puzzled me was why Garmin didn’t encode ...
No the LXT600BB is not compatible as it works off of FRS frequencies and the MB400 is a Business Band radio. Do I need a license to operate these? No! Under FCC regulations, FRS radios (transmitting power limited to 2 Watts and lower) do not need a license to operate, even if used...
decoder computes the power at each CTCSS tone frequency using the Goertzel algorithm and outputs the code with the largest power. The Goertzel algorithm provides an efficient method to compute the frequency components at predetermined frequencies, that is, the tone code frequencies used by FRS/GMRS....
Continuous one-way transmissions on FRS frequencies are prohibited by 95.193 (FRS Rule 3, "Types of Communications"). He's also in violation of 95.194 (FRS rule 4, "FRS Units") if he has attached any type of external power supply or any kind of external antenna to an FRS walkie talkie...
