Thankyou.
I can see a problem
If the radio plays the low power beep when its in power saving, something strange is happening
I don't know if the low battery beeps are playing for you, but this definitively causes problems.
I didn't hear any beeps, but perhaps I was on the verge of getting to that point at 38%.
Needless to say, I was listening on this radio for many hours today, I left the room for an hour, came back to the radio and noticed it was receiving, but there was no audio. I used another radio to confirm my suspicions. I immediately put the radio on charge for 3 hours. I have the radio on right now and have not experienced loss of audio. Tomorrow I will try to see if I experience the same thing when the battery drains to around the same percentage.
I don't know if this could be related, but at the time I was lacking audio on the GD-77, I was watching my dashboard and there were two parallel conversations being received by the gd-77 on two different time slots (which is normal for me) but they were lengthy conversations. Perhaps something was being pushed too hard signal-wise or something of the sort. Just a random bit of information.
