Thanks for the reply and the suggestion, Mike.
I found the culprit, and it was me. All is working fine now.
In checking all my filters for the fifth time, to make positively sure they were all OFF, I stumbled across one that didn't come to my attention previously, and that was a callsign filter I had set for a particular DX station.
But thank you for your suggestion, because, had I not read it, and tried again, I might not have found the culprit !!
73 to you.
