I bought several new GT-3TP for ranch use and all have varying degrees of hum/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 because he hasn't brought them back to me.
But on my new HTs, setting Battery Saver to Off doesn't remove the Low Power hum/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? Again, it's only the new HTs that do it. Older ones don't.
2) Is Battery Saver worth using at all? I got hits saying it's of no use on /r and here.
For now my workaround is to run Med power (4w) if the whine is too annoying. But I prefer to always run Low unless more is needed.
