WSAE510 Posted February 25 Report Share Posted February 25 I'm wondering how could GMRS cause interference with Ham radio? I've been hearing a lot about this and it seems like ARRL has been barking about this. Has anyone heard about that? Quote Link to comment Share on other sites More sharing options...

WRYZ926 Posted February 25 Report Share Posted February 25 GMRS should not interfere with the 2m or 70cm bands. Yes GMRS is close to 70cm but they should still not interfere. The local amateur radio club I belong to has their 2m, 70cm and GMRS repeaters and antennas all on the same tower and we don't have any issues. Plus many of us have 2m/70cm and GMRS radios in our home and vehicles without any issues. WRXB215 1 Quote Link to comment Share on other sites More sharing options...

One “statement from 2017” hardly counts as “ARRL has been barking about it.” 2017 was when the FCC overhauled the regulations for GMRS. Whenever a large rule change like that is made comments are requested as part of the proposed rule making. It may be that the “statement from 2017” was in response to that.

I've been hearing a lot about this and it seems like ARRL has been barking about this. Has anyone heard about that? This is one of the reasons that GMRS and Business/Public Safety radios are required to meet technical specifications for spurious emissions (Part 90 & 95). GMRS is pretty far away from the 70cm ham band. In fact, 70cm ham is co-located with plenty of other users (US military, radar, unlicensed transmitters like weather stations), that ham just has to deal with. There are plenty of public safety/business users between the top of the ham band (450) and GMRS, that GMRS is one the least likely to cause issues.
