MODIFIED - 1/8" Mono Plug for a 'portable' Radio's Ground Connection :
1. Remove the Tip Section of the 1/8" Mono Plug leaving
just the Rear Barrel Section and Solder Terminal.
2. Solder a Wire (Ground Wire) to the Solder Terminal.
3. Connect the Wire to Ground or the Shack's Ground.
4. Plug the 1/8" Mono Plug into the Radio's Earphone Jack.
Your Radio is now Grounded.


I might be missing something here, but ....

If I plug the modufied plug into the earphone jack, the radio's speaker
would still be taken out of the circuit. Now that the earphone jack is no
longer usable, and the speaker is no longer inline, there would be no audio.
In a strange way it makes sense, no audio, much less noise.

The cutout switch is driven off the contact for tip of the plug (which
is removed). But that also provides the spring detent force to keep
the plug from falling out.

Which is why the battery eliminator jack (coaxial power socket) may be
a better bet. If it's hooked up so that the center pin is ground,
you may be able to get a crimp on terminal (as used in a Molex connector
or RS-232 plug) that fits on the center pin without activating the
disconnect switch (that's pushed by the outer barrel). A bit of shrink
tubing is recommended to keep from shorting the two contacts. (There's
no disconnect switch on an FR-200, so I just use a (size N?) plug from
Radio Shack).
