Test conditions:
Transmit end: single transmitter, single antenna - signals combined in common TX setup
Receive end: single receive antenna, single receiver, single computer/sound card - WSPR and OP running simultaneously
Power at TX end adjusted to provide weak signal at receive end. Standard weak signal receive setup was used ... complete with QRN, QRM, other signals etc. Test began during daylight, proceded through the night and ended in daylight.

Subject: LF: QRSS OP WSPR
Bob,
For QRSS reception on 4000m, better ask G4WGT or F5WK or F6CNI for a preferred frequency. Ort maybe TF3HZ? He is reading the reflector as well. At least i saw the flag from Iceland on the flagcounter of SC8CS's new grabber which was announced here :-))
BTW, regarding OP65, Jay/W1VD recently did some tests comparing OP4 and WSPR-2. The summary was something like "WSPR-2 is as "sensitive" as OP8" !!. Correct me Jay. That means, instead transmitting OP65, you could use WSPR-15 instead and may have 4 times higher
probabbility to get a decode, e.g. if there is just a short propagation window like on 137 kHz.

Stefan;
It is same here. But you can't do everything-transmit and receive at same time no go.
I have a similar PC got from neighbor last season a Samsung less than two years old. Big difference from little ACER PC!
I think I am going to stick with QRSS 60 for anymore 73 kHz work. What freq might be best for UK/Euro work? I understand that 72.4 is not good in UK/Europe. Seems that 74.5-74.6 seems best from comments I am getting?
Any suggestions appreciated-Bob
