Continued radio problems

[rwanttaja]

Do you get the feedback when you don't plug the microphone into the headset adaptor?

I have an older Vertex Standard, now about 9 years old. Its transmission capabilities were severely limited in my P172D, so I had my IA install a connection to the aircraft's external antennas. After doing that, the transmissions were heard loud and clear at Cheyenne's tower from about 30 miles south, apparently little different from the panel mounted radios. I used my DC 13.4 headset and a Telex PTT for the test, plugged directly into the hand-held's ports with the adapters provided by Vertex. I did not use the aircraft's intercom or aircraft power.

My guess is that if you keep the hand-held's system entirely separate from your aircraft's systems, your problem will be solved.

I have a battery powered intercom in my 8A Luscombe and I have an older KX99 portable hooked up to it with a PTT switch on the stick. I also have an external antennae mounted on top of the plane. This works very well and is as clear as the panel mounts in my Bonanza. Just for kicks, I tried an ICOM (A24 I think?) hooked up to the system and it also worked very well. This is a stand-alone system (meaning not powered by the plane as the Luscombe does not have an electrical system ). I'm very happy with it.

To the OP, are you using the aircraft to power any of the units? If so, can you try it without that using only the batteries and the external antennae?
