Storing into K3 General Memory

[Mel Seyle]

In the logging software on which I'm currently working, I have been trying
to write from my software to the K3's general memory using commands
from the K3 programming guide.  I've had only partial success thus far.

Here's what I've found:

If general memory nnn is empty, one is able to write the frequency
information to it
by sending MCnnn;SWT15;SWT15;  This a little different from the sequence
used when pushing buttons on the K3, <V->M>< rotate main dial to the
desired
memory number><V->M>, but it works.

If, however, memory nnn is NOT empty, MCnnn will change the active memory
number to nnn, but will then immediately write the contents of the
memory to
the VFO's, defeating the whole purpose of the memory storage.

At first glance the obvious solution is to clear the memory first, but
to clear the memory one
must first issue MCnnn to set the memory, which will result in the contents
of memory channel nnn being written to the VFO's.

I'm sure there's a way to accomplish this, since the K3/KX3 Frequency
Editor Software
works.

I feel that I'm missing something, but don't know just what!

Can anyone help with this problem.

Thanks.

Mel,

If you're writing software to accomplish this, presumably you could save the current contents of the VFOs (etc.) and restore them after the memory-clear operation overwrites the VFOs (etc.).

Hi Mel,
The Elecraft Frequency Memory Editor reads/writes directly from/to the EEPROM locations where the memories are stored. The MC; command is used only to QSY to a memory. Programming the memories using MC; and emulating button taps will be tricky. Especially if you want to deal with things like split, repeater offsets, and PL tones. It gets complicated. As Wayne suggested, you could possibly save the contents of everything (VFO A, VFO B, mode, datamode, offset, pl tone, etc) and restore them after sending the MC; command. But it won't be easy.
