Hi John, I can not answer you question about the propagation mode.As mentioned the WSPR software, in WSPR-2 mode, receives an audio signal between 1400 Hz (RF 137400 Hz) and 1600Hz (RF 137600 Hz). With the IDC-136II receiver the WSPR-2 signal is from 137400 - 130000 = 7400 Hz and 137600 - 130000 = 7600 Hz. By using HDSDR software the frequency offset, 6000 Hz, can be removed.The sound output can be sent from HDSDR to the WSPR software using a virtual audio cable. I hope this helps. Regards, Edgar Moonah, Tasmania. |
