Re: MTR3000 On 900MHZ ham band-Need Help?

Just curious, do both rx and tx error when trying out of band? I know the mtr2000 uses a resistor array in the pa to determine band, it may be the same with the 3000.

Try Kurt Graber from KG electronics. He fixes these older boxes. Could be anything from a power supply going south to a failure in one of the modules.

I believe you would have to use lab to reflash the model number of one of the radios to match the other one, before a clone could take place. Otherwise you are stuck cutting/pasting. Pretty sure. I know, pain in the butt.
