Returning to amateur radio after a break of about 30 years, I'm having a blast with WSPR, initially with an Ensemble RXTX and, in the last week, with my newly built U2 QRSS. It's been running fine on 40m with a GPS unit attached but I may have spiked it with a dodgy power unit for the PA vdd when switching from 9v to 12v. Ever since then I've only had a couple of spots so I'm thinking something got damaged and I probably should at least replace the two BC107s.
I'm sure I'll get it working normally again soon but my question here is about the LCD display in idle mode, and in particular the three characters that follow the mode indicator "WSPR". When I first built it and it was running just fine, the code was always 100. Ever since the dodgy PSU incident it has been showing 000.
Forgive me if this newbie is the only one who doesn't know what that three digit number means, but I've had a bit of a look round here and haven't been able to find any reference to it. Could someone please enlighten me? I'm hoping it might help me get back on the air again soon!
Many thanks
