Forgot, both Preselector and RF TUNE should be at about 6.5 on their respective
logging scales.
With two different color crystals you'll find that the adjustment drifts apart with temperature
changes, but shouldn't be more than 10-20 Hz over time. If the room temp changes considerably, OR
if you don't let them both reach 'operating temperature' during the adjustment and when in use you
can see more disparity.

I was calling and calling and calling...
As soon as light dawned on Marblehead, I realized that the transceive alignment between my
recently-acquired T-4XB and R-4B #1 (The Problem Child) was off.
I assumed (wrongly) that you aligned like with the T-4X - that didn't really
work out.
In reading the procedure in the T-4XB manual, where they're telling you to adjust C61 until the
tweets zero out, I finally figured that you're listening to the carrier oscillator by putting the
RF tuning onto that other peak you hear on the 80m band. I also figured out that you had to
adjust the GAIN control while in SPOT until you could hear it.
And yet, it seems I'm still calling and nobody's answering. Is it just weird band conditions
tonight or is there another way that I could have misaligned the receiver? I am assuming the
transmitter is okay because the PO was using it with no trouble. It could be a bad assumption,
but it also seems more "right" that C61 is now more midrange than it was before (MUCH more
midrange)...
