The Radio Amateur Satellite Corporation (AMSAT) has made a request of amateurs world wide.

Recently there has been a DMR signal QRM’ing the AO-92 uplink on 435.350 or close by. Hotspots, repeaters, terrestrial simplex (anything not satellite related) should not be in 145.800 – 146.00 or 435.000 – 438.000. These frequencies are dedicated to satellite communications by international bandplan.

Please QSY these radios ASAP. Please share this notice to DMR, D-STAR, Fusion, and P25 users as well as others that might be operating in these areas.
