Has anyone used a VNA to set up taps on an amplifier tank circuit or
used one to set up taps on a coil in a transmatch? Maybe a small
capacitor on the anode lead instead of the finals to match capacitance
and then measure from the output of the amplifier with antenna relays in
"on" position. (no other power to the amp
I am thinking that the caps can be set to expected mid band capacitance
for each band. Then work on the inductor taps to get the plate impedance.
Or should I just measure the inductor and make the taps based on the
inductance measurement? It seems that if the tank circuit parts were in
place the taps would be more accurate.
I am looking for a tutorial for non engineer types. (tards )
or a simple explanation. Step by step would be nice.
This is the hard part about making an amp? right? I mean besides the
drilling and metal cutting, and locating parts. Maybe others might be
helped as well by a good explanation.
