I have a Icom 7300 purchased from Gigiparts with the Mars mod. I can’t get the 7300 to go to 6 meters. Neither receive or transmit. I can’t enter it through the keypad as it reverts back to 20m. Nor can I use the vfo to scroll up to 6 meters. It gets to 29.999 and rolls back to 0.300. I need help to resolve this problem.
