Intermittent Radio Issues

[Obaid Vanjara]

Hi All,

We seem to be having intermittent radio issues.
 

Use Case:

• We do a radio check on the ground (be it with folks in the pattern or even with a hand-held) the reply is 5/5 - Clear
• We fly in the pattern and do a radio check, the feedback we get is little scratchy but readable
• We fly out (2500 feet) and it's almost unreadable by NorCal and a tower we were flying to would not even respond back to us (maybe they could not even hear us).
• We have two radios in the stack (older) and It’s the same (switching to either).
   

I can remove and re-do the intercom/headset wiring but I am wondering if it’s a radio issue or potentially an antenna issue or something else? Trying to figure out what I can do before we take it to an avionics shop to troubleshoot.
 

Anyone who may have had similar issues in the past?
