May be  down to  time  Hugh ,

Opera is free running, so absolute time reference has no effect on the system performance ..

Stephan   should have the  solution, his night  garden uses similar things .

The other is  cpu loading ?

Subject: LF: Simultaneous decoding of WSPR on LF

So far I've been decoding Opera32, WSPR2 and WSPR15 simultaneously on an old IBM "Thinkpad" in the shack. This weekend I've managed a wireless connection to a desktop PC in the house so only a receiver is running in the shack leaving nice, clean signals.

Decoding Opera 32 is going well (3000km best so far this evening) but the PC, with the same operating system and radio software, will not decode any WSPR at the same time. I haven't yet tried running just WSPR-X (for WSPR2) on it's own but it does show a good signal on the waterfall if I arrange a 1.5kHz heterodyne in the shack. Why would a supposedly superior computer refuse to cooperate, I suspect the Realtek on-board sound card and software is not actually up to the job?
