K3 Fine/Coarse VFO settings

Eric / Wayne - This may be pilot error on my part as I have only had the
radio a few days but I noted a nuisance issue during the ARRL SSB DX
Contest. I was operating split vfo on 40M. Both VFO's were set to fine
tune. I decided to switch vfo B to coarse so I could qsy rapidly to an
announced qrg frequency above 7125. I discovered if I set vfo B to coarse
tune that vfo A also switches to coarse tune.

It would be slick if the firmware enabled independent switching of vfo A or
Vfo B to fine/coarse. That would enable fine tuning for stations on vfo A
while coarse tuning vfo B in split operation. I realize it is possible to
enter vfo B freq from keypad but that would be awkward and a hassle in an
ssb contest situation on 40M.

I also hope that as soon as the second receiver design issues settle that
Wayne will be able to produce the complete programmers reference manual. My
Microham Microkeyer has the hiccups with the K3 in some modes.

Thanks for your consideration

K3 VFO slave mode suggestion

Sorry if I missed this in the K3 manual....

I have sometimes thought it would be useful to slave the B VFO to the
A VFO. For example, changing VFO A would also change B an equal
amount; but changing B would have no effect on A.

I think it would be handy to operate split this way on the K3, with
its two VFO knobs, during contests and such. I guess that is what RIT
and XIT are for but they have always seemed a bit clumsy to me on the
K2 (don't have a K3 yet).

Anyhow, if this doesn't exist on the K3 I'd like to suggest it.

73,

This feature is in the next K3 firmware release which is in field test
right now. (Though I think they are linked both ways.)

Thanks Jim!

This split issue has been listed and Wayne is working it. It's not in the
release that is in testing now but should not be far behind.

You're right about the CAT commands. The K3 needs to send a different mode
report for FSK and PSK direct modes other than data so that devices like the
MicroKeyers and Navigators as well as digital mode programs know the
difference. You're dead on though....after the sub receiver is done.

For the record there are really two issues -

First, the user software needs to distinguish between FSK and
AFSK/FSK modes and be able to tell the sense or sideband. This
is most easily accomplished by using the existing Kenwood FSK
and FSK-R command response (MD and IF commands) for FSK-D
(it appears that FSK-R is not available in the K3) and using
the Yaesu FT-9000/FT-2000 extensions to the Kenwood command
set for AFSK_A (8h = PKT_L [Norm], Ch = PKT_U [Rev]). This
leaves Dh and Eh for DATA_A (Norm/DATA_U = Dh and Rev/Data_L
= Eh) and Fh for PSK_D. It would also be helpful if the DATA_A
display offset were made "user configurable" to allow choice of
suppressed carrier, "MARK" or "center of modulation" based on
convention for the most commonly used mode.

The second concern is the input selection for FSK_D and PSK_D.
Most software and some hardware (microHAM MK2R/MK2R+ and
microKEYER II) suppress CW output when the radio is not in
CW mode to prevent inadvertent keying if the paddles are
bumped. It will be difficult for use "straight key" or KY
command inputs with those configurations.
