Hi,
after trying to upgrade ATU with VE7VXO code, using mikroBootloader with PIC16 setting and the linear USB connection to PC, I have now the ATU that is no more recognized by firmware of linear amplifier.

Is there any way to program again the ATU?

Best 73s,

You need a Microchip programmer - PICkit3 or 4 or 5. Do you have one or can you loan one? The header to connect the PICkit programmer is on the ATU so it is a matter of "plugging it" but you do need one
