I found the fix on RadioReference. The workaround is to turn off the screen LED on trx.
That got rid of the whine.

I bought several new GT-3TP and so far those tested have a whine on trx when running Low power. Audio quality is also inferior to numerous older GT-3TPs we run on the ranch. In the past I'd noticed this whine on a batch of new UV-5Rs I programmed for a friend. The advice back then was that the newer HTs had some differences, and to turn off Battery Saver in CHIRP Setting/Basic Settings to reduce that whine. I never tested that theory.
But setting Battery Saver to Off doesn't remove my Low Power whine (recall that the GT-3TP is FCC type UV-5R, CHIRP Model BF-F8HP). So I have a couple of questions for the group:
- Any other ideas on how to remove that whine on trx?
- Is Battery Saver worth using at all? Some on RadioReference say
it's of no use.
For now my workaround is to run M Power (4w) if the whine is too annoying. But I prefer to run Low unless more is needed.
