You are right, I have tried a 90 deg plug and it helps. SO does lefthanded swinging, but this is awkward to me, a rightie.
The intital problem I had with the jack position was with the non-coiled phone cord that came the unit. Here in S Carolina, it can be uncomfortable to hunt with anything but open digiphones in the warmer months - but such phones dont come with coiled cords.
Even if they did, the coiled cords still just generally are in the way crossing right in front from that jack point in the rear. After trying several of such solutions I went ahead wth the changes seen in the following pics.

This is the phone jack as constructed from Radio Shack parts, prior to finishing and buttoning everything up. That's heat shrink tubing around the shielded cable.

Here is the jack connection when complete. Note the grommet where the cable enters the stem and the shortened jack, making it less "in the way." Also, the jack plug wasn't of the sealed type, so I back filled the plug with sealant and then screwed it together, making a water tight plug.
Okay, so once the cable is fed down through the stem and out the bottom of the arm cup, what to do with it? Here's my answer:

The little "box" that I mounted the stereo jack plug in is a miniature relay with the guts removed. It just so happens to be what I had on hand, but anything would do that fits below the arm cup.
I tried mounting it inside the stem itself, but the 1/4" jack plug was too large to comfortably fit inside the tube. I could've used a 1/8" jackplug, but I wanted to preserve the 1/4" plug feature. That way I can use a simple adapter for the 1/8" plugs common on digiphones, but still have the 1/4" connection for the full-ear type I use in the cooler months.
P.S. I have since repositioned the plug box further beneath the arm cuff, so it doesnt protrude from the rear.
