Sorry to hear there problems Kent. There haven’t been any changes I can think off to the cluster that could affect things. The only one has been hardening the cluster against doofus script kiddies.
Apart from things you may have done, have there been any HRD updates?
Kent, is this the latest (paid) V6.9 Ham Radio Deluxe, or the old V5 from 2012, free version?
If it’s the paid version, you should contact HRD support. If you can see the spots in one part of the software but not another, it sounds like an internal HRD issue (perhaps from their latest (auto?) update).
