Purchased a used Dual Band Setup on Ebay, was just short power cords, anyway when i powered it up some channels alpha display would just flash, I read the radio and found the channels that were flashing were uhf, finally found the connector on the uhf side of the KRK7db was not plugged in all the way with the short jumper cable, can now hear both units power up at the same time but can not get the radio to read or write with kpg44d v 2.02 first off when trying to write it says model type mismatch, if i tell it that it is a dual band radio tk790 deck 1 tk 890 deck 2 it still says model type mismatch if i override it makes it to about 87 percent and then shows a connection error.. Does anyone have any ideas? your help is greatly appreciated
