Great photos Brian,
Looks like its coming along nicely. Patience is a good thing to have at this 
and don't stop showing those pictures, I am sure others will get the "bug" 
save a big rig for themselves.

When I got my RCA BTA1-M, I took a week off from work and spent the
time putting the rig back together and cleaning it up. Managed to get the 
on 160, 80, 40, without to much trouble. My only gotcha was the oscillators
of which I have several. I remedied that by driving it with a PTS-40 RF
generator. Also installed PTT, with a "Foot Switch" and heavy relays for the

Keep up the good work, greeat job so far.
