    Thanks all for your help. It turns out that the unit was not sufficiently sc rewed in. The unit appeared to work but did not work completely. The insta llation manual says it needs a minimum of three turns of the Allen key and m ine only had two turns. I wiggled the unit and managed to squeeze an extra t urn into it and bingo! It works perfectly! Thanks all for your help, I can't tell you how relieved I feel... I had been trying to fix this for months. My next project is to wire in the handheld (its an Icom A3E)...

    Subject: Re: Radio not working (GNS430 and GMA240 setup)
    Sacha, I am glad my suggestion worked out to fix the 430 problem . . . Here is another tip about installing the 430 back into the receiver chassis whenever you have removed it. I don't recommend that you draw the 430 back into it chassis by only using the Allen drive screw-jack. This is hard on the small screw assembly and could cause it to fail later on. I always insert the 430 using my thumbs on the panel ends until I feel engagement resistance. Then, I take up 1 turn on the screw jack, then using my thumbs again, I press and rock the 430 further back into the chassis and then use the screw-jack to take up the slack until it is fully seated. Two reasons for doing this..... using your fingers can detect if the 430 is hanging up going into the chassis and you can stop and investigate. #2.. is to take the torqueing wear and tear off the screw- jack mechanism. It is small and uses nylon parts. It is not very durable if you are the ham fisted slam it in type.....

You can overcome the lack of adhesion to plastic by drilling some counter sunk holes on the outside of the box. Force epoxy through them to the inside and clamp your electronic guts to the inside over the epoxy. When the epoxy sets, your electronic gizmo is held by epoxy 'rivets'. If your epoxy runs, turn the project so the counter sunk holes are facing up or use a thixotrope like cabosil (fumed silica) to make it into more of a paste.

    David, Absolutely. In fact I did exactly as you said. I still can't believe it's al l working, it feels like a luxury not to have to grab the handheld everytime I need to make a radio call! I've been wondering.... Is there a way that one can wire in the handheld (Ic om A3E) to the audio panel as a standby com2? I already have an adaptor to use the headset with the handheld, but it would require me to unplug the headset from the aircraft and plug it into the ha ndheld. Is there a way that I wire things so I just have to select com2 on t he audio panel?
