Terry:
I have seen much the same thing with a DEM transverter and my K2, and I agree
with your assessment. The IF circuitry in the DEM transverters does not seem
to be designed to give anything close to a 50 ohm input impedance, especially
when set for for very low input powers. It is quite reactive, at least for my
transverter. I ended up adding a component or two inside the DEM transverter
to improve the matching, so the K2 could drive it properly.
