Using the extra reciver is a good way to check your offset. Once you hear
what it is supposed to be then you must remember that pitch from now on
and tune the other station in to that pitch. I adjusted my bfo and
sidetone pitch to match each other using a frequency counter then I tune
other stations for that pitch. It gets you in the ballpark at least.
As for the power reduction. Replace R44 with 10k ohms on 2nd mixer board.
Reselt ALC for 100 watts. This mod gives a range of 100w down to approx. 2
watts.
