If one of the outputs is tuned into a 50 ohm resistive load, it is
effectively bypassed. I just don't understand the real need for a
bypass and consider it a 'nicety'. Like if ANT2 has a resonant
multiband antenna connected, just tune it once on each band and you are
ready to go.
Perhaps someone can enlighten me about the utility of a true bypass
function.
Setting the tuner to a 50 ohm load is a better way of 'bypassing' it
than removing all the autotuner's capacitors and coils from the circuit
(which is what 'bypass' does).
Because there is some stray capacity/inductance in the board and
connections, tuning it into a dummy load cancels this out.
There was a lot of discussion on the beta test reflector about this.
It's possible that Wayne will either make bypass work per-band, or (as I
prefer) make it set the tuner (per band) to match a 50 ohm load.
Meanwhile, I just connect my dummy load and tune it (and of course the
tuner remembers the settings per band) if I want to 'bypass' the tuner
on a particular band or bands.
