Hi Jim & group,

I'm running an early HR50 serial #1119 with a rev E RF board and have just tried to update the rear panel with a new revision H board.

After installing the new rear panel board, auto-band changing with my KX3 no longer works, whereas it worked perfectly with the old rear panel board.

In addition, although the new board enumerates a COM port when the USB is connected, I can't connect to the amp via Mikrobootloader. Again, I can connect
perfectly via the old rear panel board (as long as I turn off the KX3 Serial menu function on the HR50).

Any ideas why the new, rear panel revision H board might not be compatible with my older amp?

Thanks and 73,

Hi John,

The new rear panel should be compatible with the older amps for USB but we might need to make a mod to use it with TTL serial or the FT-817 mode. The only reason to upgrade to it is to use it with USB serial band control for the Flex-1500 and other SDRs where it's getting CAT via USD to serial conversion.

If the bootloader doesn't connect, looking at what's coming out with a terminal emulator. You should see a solid string of 'E" (or maybe 'F' I can't remember) but if you start to see other characters like adjacent characters/lower case letters, we may need to replace the board. We've seen this in a few boards I even have one that does it but I can't figure out why.
