2 Royalty-Free Audio Tracks for "Cw Tone"

Very interesting tones, maybe solo oscillators or something similar :-). It was a terrible tones meeting. . .

Dl0ksc in cw qso of mar 10th, 2012, at 11. 50 utc on 10116 khz. Stable high frequency but multiple tone - spectrum. Audio frequency changes are due to my tuning of trx to hear multiple tone.
