[Elecraft] k2 firmware update problems with ATU

[Giuliano Carmignani]

I have a K2 SN 670, so I bought the upgrade firmware (2.04r and Main, i 
/ o 1:09).
All work well but the ATU is not working.
The first test that fails is CALn, no data is displayed, only ATU is 
displayed.
AGAIN IF I INSERT THE OLD MAIN FIRMWARE ATU WORK WELL AGAIN.
Firmware of KAT2 is 1.03

Thanks for any help.
