Yes, Don. Consider also that this behavior is only for the ATU menu as all
the others menu setting are correctly stored. Ciao Giorgio Da: IZ0DIO [mailto:[hidden email]] Inviato: domenica 17 settembre 2017 07:43 A: '[hidden email]' <[hidden email]> Oggetto: K2 menu issue I've a problem using my K2/100 with KAT100: every time I switch off K2 the ATU menu selection is not stored and switching on again the ATU selection is always on CAL, so I've to change it to AUTO in order to use KAT100. This is a very annoying situation: any suggestion?

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. 73, Don W3FPR On 9/17/2017 6:42 AM, IZ0DIO via Elecraft wrote: > Yes, Don.

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.

Georgio,
The last menu selection does not survive a power cycle. It is "sticky" until power off/on. ST L is the default selection upon initially entering the menu. Yes, you might have a bad address in the EEPROM. Since you have to copy the menu settings anyway, try doing a Master Reset (hold the 3, 4, and 5 buttons while powering on. If that does not fix it, replace CB U7. Once you have a replacement IC, cut the leads close to the IC body and remove the pins one at a time. Clean up with solder wick and if solder remains in the holes, heat the solder pad and push it out with a wooden toothpick or a stainless steel needle. 73, Don W3FPR On 9/17/2017 12:16 PM, IZ0DIO wrote: > 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.

Don,
again thank you for your suggestions and information. I'll look for a new EEPROM and then I'll follow your recommendations (I know the procedure to unsolder an IC, but to be honest I'm not enthusiastic to use it).
