K3 RTTY

Hi all,
I'm doing RTTY with K3(FSK D) + Micro Keyer II + MixWin 2.19. Everything is working OK ...
The only problem I encountered is: the k3 and MixW's waterfall are not displaying the same frequency .... (2210 Hz difference).
How can I fix this ?
Any help please ?
Thanks you,
73, Michel -- FM5CD

Re: K3 RTTY

Michel,

See the manual section '"Mark/Shift and Pitch Selection (PITCH)".
The tone/shift combination set on the K3 must be compatible with your
software.

Perhaps someone familiar with MixW can assist you with more detail.

Hello Michel,

i had the same problem with MixW. The solution for me was using a
different radio in the CAT settings.
TS-2000 works perfectly for me. There will be no problem since the K3 is
using the Kenwood protocoll.

Hi Michel:

I can help you. I had the same problem. Rich Ferch, VE3KI helped me.

Look at your TRCVR PTT/CAT screen in MixW. If must have zero frequency in
the FSK center fq box. Even if the box is grey, it must still be zero. To
make it zero, uncheck AFSK in place of FSK and change FSK center fq to zero.
Then check AFSK in place of FSK.

If this does not help you can send me a screen shot of the TRCVR PTT/CAT
screen and I will try to help you. If I cannot help you I know that Rich
will be able to help.

Bonjour Michel,

I am travelling right now without my radio, so I am going from memory, but
here are a couple of things to try:

First, the choice of radio type in the PTT & CAT configuration: in older
versions of MixW, there is a choice between Elecraft K2 and All Kenwoods.
With these versions, I have found that the All Kenwoods setting works
better than the Elecraft K2 setting. Data modes work differently on the K3
compared to the K2, but the K3's FSK D mode is very similar to the Kenwood
FSK mode. Therefore if you choose All Kenwoods, it should work well for
FSK D on the K3. In MixW version 2.19, there is a setting for Elecraft
K2,K3, but I do not know how well it supports the K3's FSK D mode. Try
both settings to see if this makes any difference.

If your K3's pitch in FSK D is set to 2125, I would recommend setting the
FSK center fq in MixW to 2210 Hz, i.e. 85 Hz higher than the mark tone.
That should give you a tuning indicator labelled FSK with a yellow
background, with its two markers on 2125 Hz and 2295 Hz in the waterfall.
The frequency on the waterfall at the center of this tuning indicator
should be the same as the K3's dial reading, and the frequency in the log
window and in the MixW CAT bar should also be the same. If you tune in an
RTTY signal so that the two tones are aligned on the two markers on the
tuning indicator, the mark tone should be on 2125 Hz audio. You can check
this by using the K3's SPOT button to see if the spotting tone matches the
received mark tone.
