Bryan1016 Posted July 17, 2016 Report Posted July 17, 2016 Both my com radios and my headset are set on max volume. Transmissions are clear, but just barely loud enough to hear. The intercom does give plenty of volume. Not being an avionics guy, my best solution so far is to use both hands to mash the muffs tighter against my head. Attached is a pic of my simple radio stack. Any ideas are appreciated! Quote
Hank Posted July 17, 2016 Report Posted July 17, 2016 (edited) Turn up the volume on the intercom. Try someone else's headset, yours may need work. Make sure your headset volume is turned UP and not DOWN. Clean wax out if your ears. Im all out of possibilities . . . Edited July 17, 2016 by Hank 1 Quote
rbridges Posted July 17, 2016 Report Posted July 17, 2016 I had a kma24 and I couldn't hear incoming transmissions very well. intercom was fine, though. Turned out my audio panel had a bad capacitor. Replaced it for a few hundred bucks (5 years ago) and it was fine up until the day I sold it. Quote
Yetti Posted July 17, 2016 Report Posted July 17, 2016 Try reseating all the radios. Allen wrench to turn the screw in the front panel. Pull out and push in several times. Same thing with the audio panel. Quote
Bryan1016 Posted July 17, 2016 Author Report Posted July 17, 2016 Thanks folks. I'll do all and report back! Sent from my iPhone using Tapatalk Quote
takair Posted July 17, 2016 Report Posted July 17, 2016 A few questions. Was it always like this? Have you tried radios with the intercom off? Do the results change with multiple headsets? Does side tone work (not to be confused with intercom)? Do you have music or handheld audio inputs tied in? Try pulling the audio panel breakers and listening to comm 1, does it improve? As I recall, this by-passes the processed audio and reverts to a pass through mode. Quote
Sqrtree Posted July 17, 2016 Report Posted July 17, 2016 Did you try not using the auto button and just manually select com 1/2 phone? Sent from my iPhone using Tapatalk Quote
rbridges Posted July 17, 2016 Report Posted July 17, 2016 The kma24 is pretty common. If you have a buddy with the same panel, you might try swapping them just to isolate the problem. 1 Quote
Bryan1016 Posted July 18, 2016 Author Report Posted July 18, 2016 Co-pilot jacks blew my ear drums out. Thought I'd already tried this, so I get the bone head award. Ill start with the jack. Thanks folks! Sent from my iPhone using Tapatalk 1 Quote
Bryan1016 Posted July 18, 2016 Author Report Posted July 18, 2016 Like Hank, my poor wife has probably also been wondering how much wax is in my ears. Sent from my iPhone using Tapatalk Quote
Hank Posted July 18, 2016 Report Posted July 18, 2016 My jacks are at the bottom of the panel. Standing on my head, I can adjust the tabs that contact both portions of each plug. Had tondo that once when the copilot jack appeared to have died; it was bumped as someone exited the plane, pushing the plug sideways at about 20° angle. Just a few minutes twiddling and testing fixed it. This will be much more difficult on the left side, it's not right by the door . . . Quote
Yetti Posted July 18, 2016 Report Posted July 18, 2016 Giving a ride to 18 year old and his dad. trying to get the fan going before we all cook in the aluminum oven. Throw on headset as we are moving. "Can you hear me?" "Hello" Do the cord chase. Hold up two plugs to him to show that you must connect the plugs to the plane to work. 2 Quote
