I agree with Mal. QRSS3 has shown to be about the slowest speed that is useful on 500 kc. Even at that speed only a few letters can be copied with weak signals on propagation peaks. Tonight WD2XSH/10 will beacon on 508.003 kHz starting on or before 2300Z. A combination of QRSS3 and CW at 10 wpm with a 10 second key down will be sent.
