[ARC5] 10 meter BC-454 - instability possibly found.

[Kenneth G. Gordon]

First of all, I must commend Mike's coil dope formula: it is very excellent stuff. I painted a 
layer of it on the HFO coil and it hardened to a very clear, thik coating that looks and feels 
very solid.

However, that wasn't the most important discovery I made today: the slug in the oscillator coil 
is loose as a goose. It literally wobbles around on its threaded shaft. Clearly, the least 
movement of the receiver would cause the slug to move, thereby changing the frequency to 
which it is tuned.

I haven't yet decided how I am going to tighten it without simply gluing it in place.

It took 14 complete turns to remove it, BTW.

I am thinking about attempting to embed a bit of rubber-band in the threads, or 
beeswax...maybe I can let a drop of Super Glue, or a very thin layer of it, harden on the 
threads, after which I can re-install the slug by putting a drop of Acetone inside the slug and 
screwing it on quickly.

Suggestions cheerfully accepted.
