Good Evening,
Sunny, chilly weather got me out working on the antenna again. I
added more guy line which let me flatten the angle of the enclosed V.
This will decrease the circularity of the radiation pattern favoring EW
over NS. It may not be noticeable. Drier ground lets me walk

Logan,
In the Flex USB cable setup just set the cables for Active TX Slice, so when
you switch slices (vfo’s) the amp and tuner will follow the proper TX freq.

I have a Flex 6600 with USB cables to both the KPA500 and KAT500 and the Flex
software allows me to log the USB traffic. I found that the KPA500
periodically polls the Flex with an IF;FA;FB command and gets an FA and FB
response from the Flex for the frequency currently designated for . The

A couple of suggestions:
1) Look for a key labelled “fn” on the keyboard. Pressing that while
simultaneously pressing a Function key should give you what you want.
2) Look for an HP application or control that will allow you to turn on and off
the functions, or even change them to do

OK, I have to admit that I just went back and tried it again and it does
work as it should. This morning I could make it stop working just by
switching the mode from DATA A to AFSK A. This afternoon it seems to make
no difference which is selected, they both work and with VOX. Nice to know

That may depend on your RTTY software. By convention, MOST RTTY AFSK

Just a little public service announcement that the Elecraft KAT500/KPA500

the PowerCombo works with VFO A, but not VFO B.
Most modern rigs come with dual VFO’s, of course. And many come with outright
dual receivers.
Like Wes, I have an original K3 which I have been using in AFSK-A for
years. I use N1MM+ with either MMTTY or 2Tone as the RTTY "engine". A few
months ago I installed the KIO3B upgrade in my K3. After I installed the
upgrade, AFSK-A RTTY worked right from the start using the USB audio codec.

Thank you very much for confirming that what I see isn't due to a broken K3.
I agree that if firmware can fix this, it would be very nice. Elecraft had
this particular feature listed in the feature set for the upgrade, IIRC,
which is a large reason I splurged on the upgrade. I didn't want

I've given up on making ASFK-A work with RTTY and am going back to FSK. It's

Wes, not sure why you are having success with this and I don't seem to. I'm

Max, all I've really used for RTTY has been FSK, using my MKII as the
interface. I'm sold on the fact that the signal is probably cleaner. With my
new KIO3B board I was hoping to get to a single-cable interface to greatly
simplify my setup. At least, I thought I remembered reading that this was
