Martin asked:
I finished the first step of the 80m installation - rewinding L3 on the KX1
board to have more windings.
Rather than press on and install the 80m board I'm taking the rig out to
play for field day.
Should I perform the alignment steps again?
Will the KXAT1 need re-aligned?
I'm not really sure what role L3 plays and what the effect of the different
inductance will be...
----------------------
Realignment should not be needed. L3 is a radio-frequency choke. It allows
d-c from the battery to pass to the collector of the final amplifier, but
prevents RF in the collector from flowing back through it.
At lower frequencies more inductance is needed for effective choke action.
The original L3 was designed for use on 40/30 and 20 meters. More turns for
more inductance are needed for proper operation on 80 meters, but that
doesn't affect the operation on the higher bands.
