Thanks, Don - but I just checked again this morning, and it appears

Hello everybody,
Tonight I wanted to work station on 3504kHz but was not able to tune with K3
to transmit on that frequency. Here are the facts:
- The antenna is multi-band dipole, a.k.a Van Gorden or Doublet -
137ft dipole center fed with 450 Ohm ladder line.
- I do not use KA
Ken,
I found that the AF-1 is really great for CW signals - it really lifts
them up out of the grass. I hope you find you get good value out of yours.

Don,
Please explain what you mean by "split tone". I do not understand that
term without some clarification.
For RTTY, there are two tones, usually separated by 170 Hz, and CW is a
single tone. The offset from the suppressed carrier frequency may be a
consideration in determining the actua

Happy New Year Everyone!

Dear All,
When operating CW or Rtty there is a split tone that you have to know
about. I have been reading on the HRD forums to figure this out to get
the software set up correctly. I know it has something to do with
carrier supression, but it just does not make sense to me.
So the more I re
Sort of sounds logical but it's wrong.
Let the load in the shack be 50 +j1000.
A low-pass L-net with a shunt Xc = -j501 and series Xl = j1000 will do it.

Thanks for that supporting addition, and for your work on the Smith

matter of the physics of the situation.
As you mentioned, the matching range of the KAT3 becomes greater as the
frequency is increased.

Even if you can tune a 40m wire on 160, that doesn't mean it will work
well. In my experience, short wires for the low bands are an exercise
in futility.
