Hi ... The same FSK, 100Hz shift, was received at 23°S/46°W at 4:30 UTC aprox, centered at 73.25KHz. Sometimes audible, but most of the time only detected on Spectran. Other signals: DCF77 (77.5K) de
John, That is it! Your picture shows exactly what I see on 73.3kHz. It is not RTTY but 100Hz wide FSK centred on 73.25. You evidently have a very good antenna for this direction. I would very much ap
Can't remember what the ERP for the 73.25k Rugby transmission was when I measured it last, but I think it was in the 10s of kW. With amateur signals of the order of 100mW or so, the difference in ERP

I need to do some more detective work, but I have a strong signal here in Massachusetts, from 73.2 to 73.3 kHz. There have been listings of CFH on 73.6, but perhaps they have moved down to 73.25. In
Hi Dexter & Bob I lost all signal from the 73.3 kHz RTTY station by 0100 UT last evening. QRN was very high so the signal could have been just below my noise level. Relative signal strength logged ar

Just for grins, I recorded a 15 sec .wav file of the 73.3 kHz RTTY signal and uploaded it at: www.qsl.net/w4dex/73khzRTTY.wav It sounds strong enough I almost believe it would print here if the stat
