frs -> wiring headset & ptt

[JIM JAMES]

mark- The helicopter plugs might be a tad hard to come by unless you are a pilot or have friends around airports. You can order these things from any avionics shop like Marv Golden, Chief aircraft supply, Univair, etc.off the internet. Mine came from surplus military headsets I found at an army navy store. The female plug is a little harder to come by, but most aircraft supply places can fix you up. They are like 1/4" stereo plugs only they have 3 contact bands plus the tip that allows you to use separate grounds for audio and mic. Try to get the military cord if you can because it has a shield/drain and some nylon cord down it's length. here's what i did, if you can follow me... I took the plastic cover off of a 90 degree 1/4" male phone plug and mounted it on the side of my helmet, drilling through the helmet for the three little holes in the plastic cover. They are only about 1/16", but they need to be in a place where you can put the screws through the helmet and put the little bitty nuts on the inside of the helmet. Then I drilled a 1/4" hole in the middle of the triangle formed by these 3 holes and ran the mic and audio wires through this using the military cord. I used the nylon cord and the shield inside the cord crimped into a "banjo" type end and secured it to one of the tiny bolts under the plastic cover. This acts as a strain relief and keeps the cord from pulling out of the helmet. I can swing my helmet by the cord with it anchored in place like this. The Bass Blasters are the only way to go! Hope that helps.

I agree, DIM plugs are a PITA! I don't have the schematic, and haven't heard from Peter (he just changed jobs, so is a bit busy), but I'm sure there's no relay involved (unless internal w/in the Talkabout 250). ttyl, Mark
