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
