Hi Ron,

The filter was a 200kc wide bandpass filter so you would see all the signals of interest. So may have helped with the input to the LP Pan which was the hot setup back then.

I am using it and it works PERFECTLY  on both sides of the signal.
If you want more explanation than I am prepared to provide,
Cliffs site info is still there, just not the products.

If you want to see spectrum on either side of the signal, you do not want a filter in the loop. Ideally, you would see the entire spectrum *before* any I.F. filtering on the panadapter.

The Cliffton Webb unit was specifically made for K2 exact signal/clean easy physical fit internally, and a external IF pass band filter for a clean signal no matter what kind of signals are present in your shack.
Not a area of your receiver where you want to be hacking about. Just saying.

That would be an option:

IF Adapter full kit (SMD components):

Who makes a Clifton Labs Z1000B replacement for the K2?

Ken,

Sorry, but I do not.
There is a ham in England who produces a buffer amplifier that can be
used, but I cannot recall who.
If you ask on the reflector for a Clifton Labs Z10000B replacement,
you may get some hits.
