JD, thanks for the reports. The frequency sources for QRSS30/60 and 
WSPR-15 aren't the same. The former uses an N3ZI DDS while the latter 
simply divides 10 MHz down to 185.185 kHz. So frequency jumps of the 
latter would definitely be a surprise, but not for the former where you 
noticed them. It's certainly possible that the tuning pot for the DDS is 
acting up. As far as I know it's never been touched since day 1 when it 
was set and that was quite a few years ago. I'll take a longer, closer 
look at it when that mode becomes active again.

73, Garry, K3SIW
