Hi Geoff. K8ZOA has designed a nice panadapter that I showed at my booth
at Dayton, connected to my K2. It looks very nice, and connects to a
computer for a nice display. There is also an optional GLCD display for
standalone use.

It uses a DDS chip to determine IF center frequency, so it works with
any IF up to 50 MHz. He is writing it up for QEX, and you can find out
more about it at http://www.cliftonlaboratories.com/
