Memory mode with K2

[Hans Bonnesen]

Using Ham Radio Deluxe ( free version ) with my K2 I have noticed:
 
1) at intervals the HRD locks down saying:
No connection to your radio as it has entered a memory mode.
Sitting 200 miles away this is the sad end to remote operation.
The only way out, is to pull the big switch using my cell-phone
remote off-switch. This will “kill” the K2 and its companion PC.
The K2 manual does not mention this anywhere,
or could I have overlooked something.!!!

2) Another strange behaviour is that the “TUNE”  position  is
accidentally locking in, causing the K2 to emit constantly a tuning signal.
There is apparently no way to reset the K2, and again I have to
“kill” the whole set-up by using my cell-phone remote off-switch!

Sad show indeed. —— Any similar experiences and ways to defeat the issue ?

With thanks
 
Hans, OZ5RB

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.

73,
