Just going to mess with the RX filtering on the QDX-M for 630M.
?
Does anyone know the measured input impedance there?? It has lots of variables if you calculate and I don't want to re-invent the wheel.

I have an assortment of MCL RF Transformers and will probably use something like the 8:1 ADT8-1T+ or lesser step-up.

Thanks,? N0UU
