K3 Tuning aid on digi mode

[K5DNL]

Hello All ,

After downloading the new FW 2.80 I attempted
to use the tuning aid (CWT) to zero beat a digi signal ( JT65A ) on 14076 + 200hz or 14076.2
The VFO tuned to 14075.8 or 200hz the wrong
Direction .
Maybe the FW needs to look at the side band that is selected for that digi mode , most digi modes
are upper side band.

Currently, the only supported CW displays in data modes are FSK (AFSK as
well as FSK D) -- usually for RTTY -- and PSK31 (only in mode PSK D).
Use of CWT in DATA A is not recommended as the K3 has no knowledge of
what type of signal you are tryign to tune (JT65, Pactor, Olivia, ...).

I'm surprised CWT is even available in sound card based data mode. In CW it works to center the signal to whatever SPOT frequency you selected. For the internally generated PSK and RTTY it works to center the signal on 1 KHz (fixed in the firmware.) It doesn't know what frequency you want to tune to when using sound card based software. When DATA A is selected it seems to me to be trying to help me tune the signal to 800Hz, my CW spot frequency.

If you use Fldigi then it has a QSY button that will shift a signal selected in the waterfall to a "sweet spot" that you specify. Fldigi doesn't support JT65A, though.

The tuning aid CWT works in CW, PSK and FSK only.  The auto spot feature works in
CW and PSK.

Not as much fun as making CONFIG:ALARM wake me up and start the coffee..
but tempting to try.. (ala Wallace and Gromit)

Anyway--

That reminds me.. not to forget...  Not sure if it got on the list since
the LyleFest in Mt. Vernon...

Really could very much use a MENU setting that quells VFO-B from reverting
to anything other than decoded message when decoding is enabled.  My short
term memory has it's own QSB and after the other station wizzes by, if I
don't copy it I lose it.  I hate losing it. Maybe I already lost it.. Who
are you again?

I fully appreciate the intent of the original design.  I don't wish to
take away the original design, just request that if so configured, the
decoded message remains un-changed by the apparent time-out to bring back
whatever the DISP writes to VFO-B.

And for release MCU 4+, maybe pause, rewind and replay in text only, not
KDVR-style.  I don't know if Elecraft realizes how bees knees the decoder
"widget we made for fun" turns out to be.  It's cool. Make it cooler!

And to nip it in the bud, I will not use a PC to 'cw-get'.  I operate the
K3 and just the K3.

Yes, since you mention it I would find that handy, too. My memory is hopeless, if I don't write something down the instant I heard it I've forgotten it.

Yes, I've been extremely impressed with how good the CW decoder is. I have run it in parallel with Fldigi and I could not say one is better than the other.

Any feature to preserve the decoded text would be useful for the RTTY and PSK decoders too. Although I guess you don't want to use a computer, I hope one day to be able to get the decoded text from the K3 and display it on the PC screen in KComm. (I know the firmware updater can do that, but it isn't possible to do that and get other info from the radio at the same time, which a logging program needs to do.)

[Greg - AB7R]

I believe one thing that is still planned is to be able to scroll back a
certain number of characters to see what was displayed.  I don't know how
large the scroll back buffer will be or when it will make its way to the top
of the list.
