[Elecraft] Memory mode with K2

[Don Wilhelm]

Hans,

I have never dealt with a remote K2 setup, so I have no experience with 
that - but I do know the K2 quite well when operated locally.

I suspect the No Connection problem is a problem with the remote 
operation of HRD and not the K2 - too much "computer stuff" in the 
middle to know for sure.  Have you tried just re-booting only the PC at 
the remote location?

Are you using a real serial port to connect with the K2?  If not, I 
suggest you switch to one if you can.  Many USB to serial adapters do 
not like to work well at 4800bps, so a USB to serial adapter can be a 
source of strange problems.

The next time you visit the remote site, check the TUNE function with 
the pushbutton.  Again I suspect this is a problem with the computer to 
K2 communication.  A dropped bit in the data stream can cause strange 
things to happen.

You *can* do a Master Reset on the K2, but you will lose *all* the menu 
settings, INCLUDING the CAL PLL data and the CAL FIL data - everything 
will be set back to factory defaults for the basic K2.

If you want to try doing a Master Reset, not only must you be right in 
front of the K2, but you must take the top cover (or KPA100) off. 
Before you try a Master Reset, download the K2 A to B instructions from 
the Elecraft website.  The first pages of that document lead you through 
the steps to record all your menu settings including the filter 
settings.  (You will need to internal counter probe to do that part.)

After recording the menu information, hold the 4, 5 and 6 buttons on the 
keypad while powering on.
When the initialization has completed, put the internal counter probe 
into TP1 and run CAL PLL.  The move the internal counter probe into TP2 
and re-enter the filter settings (CAL FIL).
After that, you can re-store the remainder of the menu settings and you 
should be up and running.

Yes, it is not a trivial process, and I do not recommend it except in 
extreme cases.

I do complete re-alignment and calibration of many K2s where the owner 
thought that a Master Reset would fix something.  It really is not 
normally necessary, but on rare occasions, the EEPROM that the firmware 
works from does go astray.

Maybe someone else will come up with a cure that involves HRD and not 
the K2.
