[ARC5] History of Ham Mods: Opinions?

[Jim Hill]

Thanks for the excellent tips on connecting to the power connectors.

Here's another useful topic - how do you connect to the splined shaft 
to tune a Command receiver?  I've tried using a pencil eraser (push 
and twist) and forcing a short length of copper tubing over the 
shaft.  The second choice would have worked better if I had drilled 
out the tubing so less force was needed. Years ago, a spinner knob 
and female spline to shaft adapters were available, and I purchased each type.

My personal feeling that totally unmodified sets in good condition 
should be unchanged. Those with some modifications and/or damage can 
be used, with defective parts replaced.   Most reasonably priced 
available transmitters have been modified, usually the under-chassis 
relay has been removed and lost or discarded.  Info about using the 
set without this relay would be helpful.  Years ago,  I ran the 
oscillator plate and amplifier screen at the same voltage from a 
regulated source using VR tubes and keyed this voltage.  The key was 
hot, but after being zapped a few times I was careful - but wouldn't do it now.
