 |
|
Those that I flew with to and from OSH last year know that my radio transmissions during flight were almost if not completely impossible to understand. I could back off the throttle for a slight improvement and transmissions from the ground with engine idling were ok. I use a Yaesu VXA-100 handheld radio with a headset adapter. Earlier in the summer my remote PTT switch failed and I just started using the PTT on the radio since it is mounted in front of the control stick. I had called Yaesu (now Vertex) earlier to ask if the built-in microphone was activated when using a remote PTT switch was used and their answer was yes, so there should have been no difference in using the remote or the built-in PTT. I am just now finding out that is not correct. When using a remote PTT the built-in mic is NOT activated. While troubleshooting the system tonight I discovered that you could hear a gnat landing on the radio case while using the radio's PTT switch which activates the built-in mic. My radio is somewhat hard mounted to the airframe so I was getting a lot of noise transmitted through the radio case to the built-in mic.
I have a connector ordered to repair my remote PTT switch.
