Channel1 is set to 400Mhz at 1 watt.
Channel2 is set to 475Mhz at 1 watt.
These frequencies are at the bottom and top of the range used for calibrating the UHF band as I'm sure you know.
When I key up on channel1 it measures 1 watt as expected.
When I key up on channel2 it measures 0.5 watts.
If I power cycle the radio while still on channel2 and then key up, it now measures 1 watt as it should.
If I key up on channel1 again it now measures 1.5 watts.
I'm convinced that my GD-77 hates me, and I'm beginning to think you might too!
I assume you calibrated the radio and looked at the calibration table values and they all looked OK, i.e the calibration value should not change a lot between each 5Mhz segment.
I'll try power cycling the radio, because it sounds like something is not being initialised correctly
Also, so it have this problem on frequencies well within the ham bands e.g 430Mhz and 440Mhz, or is it only on the limits of the calibration range where this is occurring ?
