I did align it using the 2022 to get a fairly flat +/-99KHz using 1kHz modulation so I am not convinced it is IF bandwidth that is the issue. What I would like to do now is test how the FM detector and audio behave with high modulation frequencies.

I could do a better check of the IF bandwidth as I have a sort of working polyskop in the garage but it is kind of heavy!
