I was just playing around with my 6700 and 0.13.10 and listening to 6 meter beacons. When I heard one, I would tune another transceiver to the same frequency to see if I could hear it. Each transceiver was using its own separate antennas. By accident, I tapped the CW key and I noticed that after the short tone was sent and while the 6700 was still hanging in semi-breakin, the noise floor of my other transceiver jumped up about 10 dB. Being curious, I enabled the MOX to see what would happen. Every time I would enable the MOX, the noise floor on the other transceiver would raise up about 10 dB. When I stopped MOX, it would drop back down. Understand, I was not transmitting, I was just enabling the MOX. I was running both transceivers off the same linear power supply. I changed that and ran each transceiver off its own supply and nothing changed with the noise. I tuned around and the noise was evident from about 38 MHz up to about 65 MHz. It was greatest between 50 and 52 MHz, then it dropped significantly. Any ideas?
