[Elecraft] R: R: K2 menu issue

[IZ0DIO]

Hello Don,
thank you for your suggestion, but before desoldering U7 (not easy) and changing it I'd like to be sure that the problem is the EEPROM. It seem a little odd to me that this problem come only with the ATU setting and it's not so usual that a single EEPROM address is damaged. Another strange behavior is that pressing MENU after switching on the radio I have on the display always the first menu element  (ST L) and not the last one I accessed before to switch off the radio.
Thank you for your help.
Ciao
Giorgio - IZ0DIO (also KW4NE)

If you are exiting the menu correctly, then the problem is likely with a memory location in the EEPROM IC U7 on the control board.
If you replace U7, you will have to do a Master Reset followed by CAL PLL and CAL FIL as well as re-entering all the other menu items.
Download the K2 A to B instructions because that contains a chart to guide you in recording the menu entries.
