[GreenKeys] need ideas for jack field

[Ralph Irish]

Joe

I have a flock of the type of jacks Roy is talking about.  They have been around here for decades
and I'm never going to use them, it appears.  They are designed to mount to a piece of insulating
material, about 7/16" thick.  They come in a large variety of styles.  All are for 1/4" phone plugs,
and some have aux. switching and others not.  I would be happy to get two bits each plus postage.
Some are 'new', that is to say unused, and others may take a bit of soldering iron time to clean
them off.  

After you do some research as indicated below, let me know if there is any interest.

73,

Ralph - W8ROI

(Another way of saying I gotta start getting rid of 'stuff' around here!)

For each there are three jacks.  In addition there are four jacks for miscellaneous devices that can be patched into any of the four loops.  (the military panel has six loops, I think.)

These jacks enable "normalling", that is connections through for the loop with no plug inserted, and connecting the plugged-in device into the loop when plug is inserted.
