Why do you say that. On my K2, the amplitude depends, in the expected
way, on the settings of those two relays, indicating an earlier injection

It's very unlikely that a post mixer birdy would move in the same way with
tuning setting.
Unfortunately
Kevin,
When I first aligned my K2 I followed the instructions written in the manual
for tuning L34 using the quote 'weak' 7 MHz birdie - more like a angry
elephant. After doing some work to reduce the number of K2 receiver
birdies, it struck me that the 7 MHz birdie signal is entering the
Kevingreat advice! Don't know why I didn't use the Spectrogram software
in the first place instead of my ears! just checked and I was a ways
off the peak, but using the PC and Spectrogram I've gained some sensitivity
without raising any noise.
Good call Kevin!

Eddy,
I cannot answer about the comparison with the Argonaut, but I can say
that the setting of L34 is very broad. If you cannot discern a peak,
then set the slug 1 1/2 turns from the top of the can.
One can usually set L34 for the best signal to noise ratio when using
Spectrogram. Listen
