I have been logged onto mowcop sdr the last three nights Fri Sat Sunday and it hasnt lost OSW beacon, LEX image came up after midnight on Sat and Sun. but is down in the noise now.
OSW is S7 on the SDR meter.
One tip, you may already know this but, on the Waterfall settings
Under view select weak sigs it helps show up weaker signals.
If you already knew this then carry on, as you were hee hee
