Jim,
You need to use FSK-D, not AFSK-A, to do CW-to-RTTY. AFSK-A is an
audio-transmit mode, like DATA-A, while FSK-D is for direct input
from either a computer or the K3's keyer paddle.
This is covered pretty well in the owner's manual, around page 34
(CW-to-DATA).

Sure, Marian. Just set CONFIG:KAT3 to LCSET, then exit the menu. Next,
tap ATU TUNE. Instead of starting ATU tuning, this will display the L

In fact you can then tap ANT to change Ct/Ca, and rotate VFO A and B to

The K3 is virtually desense-proof, with a BDR of ~140 dB. But to take
advantage of this, you need a narrow crystal filter -- the closer to
the DSP bandwidth the better. This is exactly the situation that we had

Steve,
Since I wrote the firmware in question I thought I'd jump in here.
When you vary the K3's CONFIG:CW WGHT parameter, it changes the length
of both dots and dashes in relation to the spaces between them. I just
looked at the RF envelope on an oscilloscope to verify this.
I'm not saying

I'll fix this right away and release firmware on Monday (hopefully).

Already fixed and being tested. I'm hoping to do a beta release of rev
3.11 tomorrow. If anyone is inconvenienced by the sidetone pitch-change
problem and would like to try 3.11 now, please email me directly.

Hi all,
We're hoping that the latest K3 beta firmware, revision 3.11 (DSP 2.15)
will go to production firmware status next week. While 3.11 doesn't
have everything that everyone has asked for, it's a huge step forward
from the previous production revision (2.78).

You're right, Paul -- I skimmed right past the pink idea (oops) and
interpreted the poster's concern as a more common one that customers
have brought up, namely that they can hear higher-order products (above

Hi Terry,
This was a bit of an experiment when we designed our first product, the
K2, about 10 years ago. But we've used the same method on many products
since then, and it works very well, keeping things light yet rigid. Our
little 2D fasteners are an integral part of these designs, holding

Wayne, I have thought about your unique construction technique and am
impressed with the results. When the K3 box arrived a year ago I

Hi Johnny,
- turn the sub RX on
- set VFO A to the desired frequency and FM mode
- tap AB twice to copy all A settings to B, then move B to the desired
frequency
- use BSET to make sure the sub's antenna is set to MAIN, then exit BSET
- set up squelch for main and sub (see SQ MAIN and SQ SUB
