Guest Buck Posted April 28, 2016 Report Share Posted April 28, 2016 I am considering getting into GMRS. Does the FCC allocate the frequency a repeater may use so that there are not several repeaters on the same frequency in the same general area? Also, if a GMRS license holder wants to operate simplex on a repeater output frequency is that legal and if so does that not create a lot of interference problems and negate the repeaters usefulness? Can the repeater owner claim rights to that frequency? Quote Link to comment Share on other sites More sharing options...
Guest Harry Henderson Posted April 28, 2016 Report Share Posted April 28, 2016 Buck I would check around your area for a local coordinator, And no a frequency can not be claimed from what i read.If I am wrong someone please step in, as for a simplex repeater it would be the older members of the group that mightbe able to answer that as I am still to new to GMRS radio to answer.

coryb27 Posted April 28, 2016 Report Share Posted April 28, 2016 You could go out and invest $4k bucks on a repeater and put it on a well placed site with a 200' high antenna and the guy down the block could grab 2 mobiles and stick a repeater in his back yard on the same channel and there is nothing you can do. You can try to work it out but if you cant nobody can help you. Operating simplex on a repeater output would be the proper way to use simplex on GMRS, this results to what is known as talk around. Several repeaters can co exist on the same channel as long as everybody is using a different pl/dpl the only time its going to be an issue is when both are transmitting at the same time, the better repeater most always wins. GMRS Operators tend to work together and solve most interference issues unless one is a total jerk. Corey Hans 1 Quote Link to comment Share on other sites More sharing options...
SteveC7010 Posted April 28, 2016 Report Share Posted April 28, 2016 I am considering getting into GMRS.

Can the repeater owner claim rights to that frequency? There are no "allocations" by the FCC to prevent multiple repeaters in the same area on the same repeater pair. Part 95 simply defines 8 repeater pairs for GMRS. Two of them have geographical restrictions regarding proximity to Canada. As far as I know, there is no formal coordinator system in GMRS, at least certainly not authorized or required by the FCC who has the only legit jurisdiction in these matters. As Corey pointed out, GMRS repeater operators geographically close to each other tend to work these things out between themselves. Part 95 never grants exclusive rights to a frequency, in fact it's quite the opposite. GMRS users are required to share the channels. There is no exclusivity in most LMR services. Here's a link to an easy to read online version of Part 95. It should answer most of your questions. https://www.law.cornell.edu/cfr/text/47/part-95 There are many other resources for Part 95; do a google search using fcc part 95 and you'll get plenty of useful hits. Also, using the search function here on mygmrs.com will locate many previous discussions on the same topics. Hans and coryb27 2 Quote Link to comment Share on other sites More sharing options...

Guest ALBERTO MADEIRA JR Posted January 2, 2017 Report Share Posted January 2, 2017 Whats the difference if any between Part 95 and 95a? Quote Link to comment Share on other sites More sharing options...

SteveC7010 Posted January 3, 2017 Report Share Posted January 3, 2017 Whats the difference if any between Part 95 and 95a?95a is the portion of Part 95 which deals with GMRS. If you had taken the time to actually read 95, you would already know this. That is why the link to Part 95 was posted earlier in the thread.
