[Elecraft] Characteristic Impedances

Which filters are you referring to?  If it is the K2, clearly the BPF's are 
50 ohms in and out.  It is not so clear about the LPF.  It could be doing 
some impedance transformation to match the output impedance of the amplifier 
on different bands.

Gang-

Can anyone tell me the design values for the termination impedances for both 
the bandpass and lowpass circuits.  I'd be ever so happy if it is 50 Ohms.

Thanks,
