Whine on trx Low Power in new batch of GT-3TP Baofengs
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:
1) Any other ideas on how to remove that whine on trx? 2) 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.

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