Amen to that whole list. Well, HF squelch would be awesome, but that is

Longer auto-off would be lovely. My KX3 kept turning itself off while I was

Sorry, Aaron, I wasn't clear. I'm talking about the freq displays on the

I was several releases back and just installed this beta so my question
probably applies to an earlier release.
I was dismayed to see that frequency display resolution (all 3 of them) is
now down to the the single Hz! That's three decimal places. I always

I haven’t tried this yet specifically to see if it can outwit the AGC, but it
is often useful to flip to CW reverse to get the QRMer on the other side of the
skirt.
But during a contest, like this past weekend, when no-one is supposed to be
operating split, I don’t know how much an S&P station
I'm pretty much full time CW and rarely leave the 400 Hz filter.

Jorge,
JT65 is "just another data mode", and like other data modes, you must
drive the K3 audio up until you have 4 bars solid on the ALC meter with
the 5th bar flashing.
Adjust the computer soundcard output and the K3 LINE IN Gain to achieve
that condition. You do not have to transmit while

Oh yes, I had forgotten bias as well - ptt/bias/updown should definitely

Ed,
I don't know what audio card you are using, but if it has a stereo plug
on the KX3 end of the cable, it should not turn on PTT.
If it does, I suggest you make up a special cable with stereo plugs at
both ends, and connect only the tip and shell of the plugs.
That should eliminate your prob

Ramon, Thanks for the advice. That is probably what my difficulty is; I
will check when I get back to the rig tonight.
Don, I realized after I sent the message that I meant CHU, (not WWV) but
did not want to make another post just for the correction. The basic
memory question was valid tho
What "40 meter WWV frequency" - WWV transmits on 5, 10, 15 and 20MHz.
If you want to set a memory to 10MHz WWV, you should select 30 meters,
tune to 10.000.00 and set the memory from there.

Mike,
Think about it - if there are multiple signals in the passband, the AGC
will respond to the strongest, there is just no way around that fact.
If the signals can be separated by the DSP, and one is really strong,
that strong station may be activating the Hardware AGC. The only
solution f
Sounds like very strong signals with fast agc with its decay set well into
fast range. And if you have stations using spot frequency that will really
muddle them.
I have my fast agc set to its slowest possible decay and my slow agc set to
fastest possible decay. Then I only use the fast in heavy q

I do not have the internal antenna tuner but I believe that you do not
