[Milsurplus] [Boatanchors] RAL, RBA, RBC Manuals and info needed

[Jim Hill]

If I remember correctly, I have manuals for all three.  I could have 
Kinco's repro them, but there are plenty of pages ($$).

I think a UHF "barrel", or female to female connector will plug into 
the antenna connector, and a banana plug will go into the other end 
of the barrel so you can use a random length wire for an antenna.

There are some "gotcha" when servicing the RF coil boxes

Electrical connections are made with metal strips, connected with 
machine screws to threaded openings on short ceramic standoffs. After 
removing and opening things, you will end up with machine screws of 
slightly different lengths.  Be sure to use the shorter screws for 
the ceramic standoffs.  The longer ones will bottom, and when you 
tighten further to secure a strip, the ceramic breaks.

The coils have adjustable slugs with slots machined in threaded brass 
rods.  Be very careful to not bottom them.  The slugs will jam, and 
one side of the slot will break off when you attempt to move them in 
the other direction.  It's easier than you might think to end up with 
a parts radio.

There's also a tongue in cheek gotcha   Work on them while you are 
young.  As you get older, you will have issues when moving them.

I could never adjust the antenna box to remain in resonance across an 
entire band when using a random wire.  As you tune, you keep moving 
the antenna tuner in one direction until you are at the end of 
travel.  However, the radio still worked pretty well.
