The Vienna VA beacon is evident at 1 kHz. The Front Royal VA beacon is barely visible 5 Hz lower. This display is horizontal. We searched for the British signals by setting the RX320 on 137.750 kHz. The output of 137.750 then occurs at 1 kHz.
Higher signals occur higher and so forth.
Here the display is vertical and many weak signals can be seen but we were never able to identify Morse code related to anything that made sense. Even though the CW characters may not be read, the periodic gap helps to discern the difference between our signal and various spurious carriers. We took less stuff because we now know more about what works. It made the trip easier. We tried a kerosene heater in the garage.
