Steve -
It takes very little movement of the shield can to shift the frequency. Properly fitted, you should
be able to push gently on the can without disturbing the frequency

Glued in the end piece flush with the end of the coil form, oriented in a diamond. Fired up the
R-4 and after warm-up, the problem came back as bad as ever.
How tight does that cover have to be? The clips are a little deformed and they're fairly easy to
disengage. If I touch the enclosure it is extremely sensitive. It sounds chirpy and the
frequency goes up and down all the time - without touching anything. I'm about ready to up on
that offer to send this out for a second set of eyes (and a second brain) to check it out.
It's obvious why the asking price of this set was as low as it was when I bought it - not that I'm
complaining as cosmetically these are about a 7 on the chassis and an 8 on the outside. I just
want the chirping to be confined to the goldfinches outside my window :)
Calling it a night...

Steve ,
It needs to be oriented in a diamond shape. The brass end shaft rides in the " V
", not the flat.
