Hearing beeps on 6927.9 and 6929.1 every few seconds. Close to noise level so not sure if I'm missing some of the beeps but the timing doesn't seem to be the same all the time. When tuned in USB mode (right now tuner is set on 6927.0 kHz USB) sounds like two different tones going at the same time. The frequencies 6927.9 and 6929.1 are where the dots are showing up on the SDR waterfall.
