FL760 , transmissions are 1/5

[echostar7]

I flew today and I was told that I was broken and barely readable on the radio but I could receive very clearly. I tried two different headsets and there was no change in my transmissions clarity. What can be the cause? Only new thing I can think of is I added the GDL-82, can that interfere somehow with the com, or just a coincidence?

The fact that you can receive just fine. But, transmit is "1/5", makes me think its more than likely VSWR problem. When was the last time that radio transmitted good? And, did it ever work ok after you installed the GDL 82?

The GDL 82 has nothing to do with your com radio. But, is it possible you disconnected the coax from the com antenna and forgot to hook it up? Or, maybe the coax connecter was damaged while installing the GDL 82?

I asked for a radio check today and it was loud and clear to whoever responded at the field. It may be a different story though for artcc miles away, I'll inspect the coax connections for damage, thanks.

Another thing too: on some radios its easy to get the box a little off when reinstalling it in the rack. Especially if you're not very familiar with how the latching mechanism works.

If you had your com radio out during the GDL-82 install, you might just try re-racking it to make sure it is properly seated.

Agree with Ken. On receive, nearly anything (coat hangar) works for an antenna. Transmit is a lot fussier. Specifically, look for good connections where the coax shield is attached to the connector, and where the connector attaches to ground. Both at the transmitter but especially at the antenna end. May be something as simple as corrosion between the connector and ground.

What was the weather like that day. We lost all our coms after flying around/through a storm cell. Once the weather got better and everything dried out the comms have worked great. Several people mentions it was likely static build up. When I returned home we checked/rebedded all the antennas.
