When I worked for a small company repairing test equipment for the telephone industry we got into the habit of automatically replacing batteries because we found out the hard way that the batteries may have plenty of voltage but not the current capacity. That sounds like your problem.

Your batteries might have the voltage on powerup, but not the amperage. If you can plug in your radio thru a cigarette lighter plug, you can test this. The light plug will put out more amperage.?

The one with the UHF problem may be drawing excessive current at high power.
Does the LCD display blink out when you key up? Many newer radios monitor for
low battery voltage and shut down until the voltage comes back up.

I have 2 FT-60's. One works fine, one shuts down and restarts when I transmit on UHF at high power. Only on high power; does not do this on Low or ExLow power. Switched out identical antennas between the radios. Same issue. Switched out batteries. Same issue on the "restart" radio. Fully capable batteries on each, showing 8.0 and 8.1 V on startup. (I know a weak battery show the same result.) Can anyone think of a reason for failure on high power on UHF (same all across the band)? VHF works fine across the band on all power settings. Suspecting something inside and not the hand holding the radio....Thx, 73, Bob
