Hi Mike,
I think that actually this is a great feature. The fancy operation
brings a healthy laugh to the DXers and drives the QRMers crazy as
there is no single TX frequency :).

Hi,
Occasionally DXpeds lose their split setting which causes chaos when
running a pile. The usual comment is it's a K3 thing. The question
is why is it?
I use Logger32 and when I click on a spot whilst in split mode, the
K3 QSYs and split is cancelled.
At first I thought it was because that Config: SPLT SV was NO so I
changed it to YES but this didn't make any difference. Certainly I
could change band and return and split was indeed saved.
Next I put the K3 in split and then entered a frequency in the same
band in the L32 log entry window, the K3 QSYed and split cancelled.
Next restored split and entered a frequency from the K3 keypad,
split stayed on.
OK, looked at what was happening on the com port serving the K3.
When L32 sends the frequency to the K3 it prefixes it with FR0 which
according to the programmers reference cancels split mode. So the
response of the K3 was to be expected. A typical example is:
Set Radio Freq/Mode: FR0;00018160000;MD2;FA0018160000;
No idea what other software does in these circumstances. However,
if popular DXped software, N1MM or the like does something similar
it will be easy for a DXped operator to unknowingly and unnoticed
cancel split and go walkabout whilst tuning the pileup.
Clearly FR0 is a useful command, I use it in an RTTY macro to cancel
split. I guess that the L32 development team assume that if you
enter a QSY you intend to come out of split so include the FR0,
reasonable I guess for a home operation. Users of alternative
applications might wish to conduct the same tests.
The simple answer is better cockpit drill by the DXped operator.
But even having set up the correct band/mode/filter/antenna etc it
is still easy to accidentally cancel split under pressure, it's a K3
thing, is it?
Have I missed something?
Your thoughts please gentlemen,
Mike VP8NO
