TK-880 in Crop dusting aircraft audio help needed
Does anyone have any good experience with quality helmet TX audio utilizing a aircraft helmet with noise canceling mic for a UHF LTR 12.5kc sys?
Utilizing a home grown mic bias interface the TX audio quality is very poor when the aircraft is in the air.
When on the ground or not running at all the TX quality is quite good.
any help would be appriciated.
Thanks!

I'm always willing to learn.
I guess maybe I'm to much of a city slicker. I thought all aircraft had to have aircraft radios to talk to there local controllers for any clearence into airspace.n5tbu wrote:I have never seen a duster with an aircraft radio in it!
I know that some of the Traffic Planes in the Boston area use the accessory port on the back of there radios.

The helmets are connected to the rear accessory port of the radios with some quick disconnect avaiation audio jacks. NO switching.
n5tbu,
Yes it is getting engine/wind noise, and they do kiss the mic.
It is extreemly bad IMO while the aircraft is in the air. ON the ground everything is fine.
