Re: Which SDR for pan adaptor on a 9MHz IF output?

As far as I can see there are only bandpass filters in front of the
IF tap, most users of FTdx-5000 sets seem to use it for their
external panadaptor, but thanks for the heads up. I have decided to
keep it cheap and simple and use a (admittedly USB...) Softrock Lite
II on 9MHz for now to see how I get on with this thing. Thank you to
all who have replied, appreciated.
