There seems to be a lot of speculating from HAM and new users! If you do the leg work. You will find in the OLD PT (95) rules ware the FCC states they will NO LONGER issue pairs of frequencies for linking! For those that claim that the FCC never meant for GMRS to be linked that is bs. The FCC has always said no autopatches, and no ptsn. Wonder why the phone company lobbied so hard to keep telephone off GMRS? Maybe they didn't want competition for cell phones in areas the cell company's are lacking. For the HAM that says you have to have a license to use radios? I believe anything 500mw and less the FCC don't regulate! IE: FRS and some other bands. And for those that don't live along the Mexico border! GMRS is illegal in MEXICO but the Mexicans are running 467.550-467.725 as DMR out puts for Motorola DMR trunking systems jamming Sothern California through Los Angeles and even into AZ. The FCC admitted years ago stating that in the advent of FRS that type acceptance never talked to enforcement and there were issues caused to frs and GMRS from the start but to change things at that point would cause them to be sued by manufacturers that built to specs. Also if you do some research in FCC part (90) you will find out the the FCC and the frequency coordinators to date all VIOLATE FCC rules daily when issuing licenses and this is a fact. Do a bit of leg work and you will find that the FCC and agents for promote jamming of LMR repeater systems!!! Yes no BS. Frequency coordinators constantly assign users to areas they are not to be assigned to! ANY GOV entity has protected spectrum and the FCC and its agents are illegally putting people in part 90 that do not belong! Any school district, fire department, Indian reservation, and others ALL have protected spectrum that is not being used by whom belongs in it! Oh and I forgot to mention in part 90 the FCC daily approves JAMMERS AKA users a license to talk on LMR repeater inputs not the outputs the FCC allows new licensees to talk simplex on the inputs of commercial frequencies and these people have no clue they are interfering with the repeaters. This is my two cents. Yes its all verifiable if you do some leg work or ask AI to do it for you! I personally think the HAMS should loose a bunch of unused spectrum they all will cry about it but if you look in the two meter / four forty spectrum they link way too much in some towns trying to protect spectrum. Given the opportunity I would link all 8 channels of GMRS as needed to keep the Mexico traffic out of the us! The FCC don't seem to care if your NOT CAUSING HARMFUL INTERFERENCE! What is the true definition of HARMFUL INTERFERENCE! Under the FCC subject to change with out notice! Again just what I have researched over 50 years. There will be a bunch of but sore hams because of my comments but they won't do any research first!
