Well, it's taken a whole lot longer than it should have, but the day
has finally arrived. Thanks to Gary at AMfone, the updated list of 30K

Hi Don, if you don't find one here, try the Johnson
Reflector.

Just wonder if someone has a parts Johnson Viking Valiant

I am restoring a Viking Valiant I and found out today that
my meter is

I have a Morrow Falcon receiver and need a schematic
or manual for it. Will pay for a copy and shipping and
handling. Please email me direct. Thanks and 73, John,

I need to make a couple of RF connections using 1/4 O.D. tubing. The stuff
that is already in the transmitter appears to be soft steel of some kind.
It's not aluminum and could possibly be coated copper. Any ideas of what
this is? I checked McMaster-Carr and they have some annealed steel
Automobile air conditioning line? Or perhaps tubing from a refrigerator?

Rick what are these connections in, type of radio, etc?
That might help identify what the composition of the tubing
is.

Thanks Bill, good idea.
Jim... I need to make connections to and from the antenna and capacitor in a
GE BT-20-A broadcast transmitter. I could use heavy wire since it is only
250 watts and not in continuous service as it was when used commercially,
but I'd like to keep it as original looking as
Are the connections soldered? Is there any tubing in it
presently, and if so, is it soft enough to bend by hand?

Jim,
Yes, the connections are soldered to eye terminals. The tubing can be bent
and shaped by hand. It seems to be about like soft drawn copper tubing of
that size.
Joe... Brake line my do the trick.
Thanks,

Good guess, use copper tubing from your favorite home center store!
What you see in the transmitter is more likely than not silver plated
copper tubing.

I would stay with copper, plated with tin or silver (you can get silver-dip
to plate copper, though it is expensive).
Steel, particularly stainless steel is a poor RF conductor. You'd be better
off with aluminum.
Are you trying to make coaxial cable or just use large conductors between
A magnet should tell you if it is steel.
