I previously listed this for sale and (erroneously as it turns out) indicated it might be the one used in the HR-1680.  Wrong-o. It is positively the filter set used in the HW-2036(A).  

Thanks to Terry Perdue for first raising the red flag and then to Bob, G3OOU, who provided a schematic and partial manual which positively shows that the IF filter set is the one I have.

So I still have a filter set (HPN 404-573) for the HW-2036 (and probably the HW-2036A) which I don't need.  If you need one or would like one, just drop me a line at <rgroh at swbell.net> and I'll give you a nice low price.

73 and thanks to Terry and Bob.
