Don,
That is a totally great looking meter!!
I will have to put that on my to do some day list.

Recently completed installation of
the Cumbria Designs X-Lock in my TR7.? I'm extremely
happy with the final results.? Just thought I'd post a
link to my webpage relating to a small twist I made relating
to the tri-color status LED placement.
I hope you guys find it a good alternative to using the
FIXED lamp on the TR7.

BTW, has anyone installed the X-Lock in any of the 4-Line
equipment?

Jim,
My observations on the TR7's PTO is that if the ambient room temperature
is around 70 F, the PTO is quite stable after initial warm up. If on the
other hand the house temperature is something other than 70 F the thing
wants to go all over the place and never really settles down. Oh, I do
have the FA-7, and it was used during the above observations.
The X-lock was the absolute best time and $$ investment that I put into my
TR7.

I think the TR-7 is more prone to thermal drift from
temperature variations
over transmit-receive cycles. My tests have shown that
adding an FA-7 (or
equivalent) fan, properly oriented to pull air out of the
radio, helps with
this. Running on an RV-7 also helps. My TR-7 drifted more
than it should have
before I opened up the PTO and checked things over in
there. It's been long
enough ago that I don't remember, but I imagine I probably
touched up some
solder joints. I'm really picky that way... :)

That is indeed very interesting. I shouldn't think that it would do that.
Makes
me wonder if there isn't something else going on somewhere.

I've never noticed my TR7 wandering around in frequency after about 30 sec
of warm up. I grew up on tube gear so I'm not real fussy about such
stuff,
but I don't think it drifts any more than my Omni VI+ for example.
Just another data point

Ref: Drake TR-7, I need Help!! I fired my 1KW moblie rig up about 10 feet
from my vertical antenna, which was connected to my Drake TR-7. The TR-7
transmit and receive is gone. Is there some type of protection circuit
that I might have knocked out or did I just kill my TR-7 for good. Thanks
in advance..

You may have killed the mixer brick on the Upconverter board. That would
take
out both TX and RX. It's a diode ring mixer module, with modern
replacements.
Info can be found in the list archive.

I just picked up a TR 3 and have enjoyed learning about tube ham radios. I
did get a copy of a manual which has been very helpful.
I read all the TR 3 posts in the archives and figured out it needed the
jumper resoldered on the VFO plug and now it works and it
gets better every day. I am going to send it to Jeff in Ohio for new caps
and a tune up and have the power supply rebuilt.
I do find it is the loudest on 20 meters 40 is good 80 meters is nice and
quiet and clear. 10 and 15 meters I have heard people out
there but the volume is very low. Is this just the way they work or could
it be bad paper caps? Anyway thanks for having this group,
I will go back and read anything for the 3 and 4 series to see what else I
can learn.
