Thanks Joe.

About 80 dB give or take a bit.

Uh-oh. This could turn out to be very embarrassing. I am
aware of receiver images and have run into issues with that
in the past... however, somehow managed to develop
selective amnesia while working on the current problem!
I just checked all the radios I've been using to monitor
this spur in-house and all *do* have a 455 kHz IF. I will
have to check the others which may take a day or two. Let
me also see if I can find a receiver which does *not* use a
455 kHz IF to check it with.
I will let you all know if I have made a really big
blunder...
