BJ and I are having the devil of a time with line noise. As soon as one
thing in the neighborhood is fixed, a week later another is trouble. We
won't let up on the calling about the trouble but in between the fixes, it
would be nice to be able to operate. We would really like to experiment
with
Last week I drove 1600 miles round trip to pick up a 1934 Gross
CP-100 transmitter in stunning condition. Alas there was no
documentation with it. Does any one here have any CP-100 info
or leads on info? A couple of my Gross Friends, hee hee hee, are
looking for Gross info as well, specifically

John,
I'd like to know how your progress goes on the issue. I had a similar
problem at my former QTH, and HF communication was all but shut down. 80M
was the best band with a line noise of about S9+20, and 10M w

This is the transmitter that I bought from Universal.

I took time-out from the R-3** and BTA-1R2 and BC-610 and so on to get
the G-50 I bought a while back in operation. After stuffing the filter
capacitors and replacing a couple of capacitors in the cathode circuit
of the speech amp/preamp combo the G-50 came to life. However, I find
now that
It's very unlikely that the Gross CP-100 ever used a
TZ20. The Taylor TZ-series tubes were designed for
grounded grid operation and usually used in pairs or
quads.
Also, Gross seems to have labeled it's transmitters
with a model number that was intended to indicate the
watts input of the rig. and
Rick,
Yes, that is probably just polymerized grease.
Take either a hot air gun or even a propane torch and gently hear up the
shaft to melt the old grease.
Quickly displace the old molten grease out with WD40.
Then cool, wipe the area down and repack with fresh grease.

Thanks Mark. I'll give your idea a shot. I'll do almost anything to
prevent having to take it off the chassis. I need to do an alignment on
it and I want to get this resolved first. I am hearing a few stations
on and would like to get in the mix. It's been many moons since I
worked 6 meter
On Behalf Of Rick Brashear
owever, I find
now that the variable capacitor on the receive VFO is having turning
problems. It's one of those geared internally capacitors with one shaft
inside another one. I guess the friction clutch or whatever makes those
things tick is worn out or maybe oily. D
