Split-mode problem

I have a weird one here. Intermittently, when I put my K3 into split mode, with the VFO A in SSB, the VFO B will turn up in CW or FM mode. In all cases I remember, VFO B was last in SSB mode, so the mode change happens when the Split is executed. Usually, I set the split within MacLoggerDX, my logging program. It is quite intermittent, so I have not used the front panel controls to set split.

My K3 is only in CW when I am tuning a remote tuner, and only in FM on the rare occasion there is DX in the upper 10M band. Both occasions would be using VFO A. I do NOT have a second RX installed.

I sent a console log the the logging software developer, and he was at a loss to explain the problem from an application perspective. I assume it is in the K3 somewhere, maybe an config setting that I messed up by accident. I am not a heavy K3 user, so I may have overlooked something simple. I would estimate the problem happens 20% of the time I go to Split mode.

I have decreased the Comm port speed, to no avail.

Any ideas?

Re: Split-mode problem

Randy,

I think that is normal operation if you simply turn on SPLIT without
doing anything additional.
If VFO B is not in the same mode as VFO A, you will transmit with
whatever mode VFO B had been set for. Yes, VFO A and VFO B can be in
different modes.

The normal complete procedure for entering SPLIT (unless you know you
have the VFO B mode, frequency, etc set up beforehand) is to tap A>B
twice (once only copies the frequency, twice also copies mode, etc.) and
then move VFO B to the split frequency, then finally tap SPLIT.

I don't know what the details of your MacLogger macros that you are
using actually accomplish, but they can likely be created to do all the
above actions in one macro. The information about how to set them up
should be in the MacLogger help file for its end and the K3 Programmer's
reference for the K3 part of it (which commands to enter and in what order).

Re: Split-mode problem

Correction all,

2nd paragraph, last sentence. I wrote "tap" SPLIT -- well that will not
work, one must HOLD the button to enter SPLIT.

Sorry for not proofreading before hitting Send.
