What i don't like is so far it is eating through enelope batteries at the rate of 3 fresh ones every 8 hours. Any one know if this is an ok rate?
From my experience with the battery charge, yes ~8 hours.
I don't like the fact that i can't plug the scanner in and scan while it charges the batts or with batts in the unit or out of the unit like past models can.
Actually you can power the radio from the USB. When you plug in the supply it will ask you "USB Cable Detected Select USB mode. Mass Storage = "E", Serial Port = ".". Just select serial port, then it will scan while on external power. Without batteries in the radio, select the Serial Port "."
It should ask you if you want to charge the batteries when you plug in the USB, or tell you that there are no batteries.
