Who controls the freq use on simplex 2 meters with these relay links kz4usa 2 weeks, 3 days ago
You may be experiencing the effects of Third Order Intermodulation Distortion. That happens when two strong, evenly spaced signals are picked up on your antenna system and mix in the front end of your receiver. It can appear out of no where and sound like data, beeping, or as a voice transmission. Example, you are tuned to 146.520. Two strong signals are present at 151.520 and 156.520 MHz, which create a phantom signal at 146.520 MHz.

You can get rid of 3 IMD by using a transceiver that has a higher 3 IMD DR than the one you are currently using, or use an antenna with less gain.

As far as who controls the frequencies; they are usually coordinated by a volunteer frequency coordinator, but each licensed Radio Amateur has the right to transmit on frequencies for which he or she is licensed to, with the hope that they will use good judgement.

Band plan KM4OPN on 16/12/16
Broadcasting, No.

Broadcasting (one way transmissions, excluding remote control) is not permitted on any Amateur band. Two way Amateur transmissions are permitted on the entire 6 meter band for all Radio Amateurs, including techs. Keep in mind that 50 to 50.1 MHz is CW only.

Have Fun!

Max RF power for Yaesu 857 with digimodes? KJ6BQM on 4/10/16
If you keep the RF output to 30 Watts maximum, you will be just fine using digital modes. For your own comfort, reach around the back. If you cannot touch the radio because it's too hot, then take a break.from transmitting.
