Folks, I'm having a problem with my SL40.
As this is my only on board radio I need to solve this rather quickly and don't really know where to start, looking for suggestions.
I have an SL40 transceiver wired to a GMA 240 audio panel. This is a new installation as we just started flying.
The problem is that the unit is transmitting fine it seems, but the reception is very weak and crackly to nothing at all.
On the ramp, and standing 20' away with a handheld, everything seems fine. In fact, often, inside the hanger I can receive other aircraft outside.
Once the engine is fired up and taxiing to the runway and all during flight, the reception gets horrible or worse.
Right now, I know the wiring from the audio panel is fine as audio from the EFIS to the head set is fine. I'm not sure at the moment if anything gets from the radio to the headsets or not. Waiting on an answer from Jeff Point (my test pilot) as to whether or not he was able to un-squelch the radio in flight and at least get static in his ears.
Do I look to the antenna? I'm not a radio guy, but it seems that must work fine if the transmit function works ok, but I've been wrong now and again.
The radio tray came with a 90 degree antenna attachment on the back of it. Are these things ever a problem?
Do new radios ever ship defective?
Just looking for some direction here. No experience what so ever in this kind of stuff. Thanks for your help.
