Hi Ron and the group
I hope you got your equipment to work on RTTY yesterday but if you didn't I
have been there and done that several times. I didn't see anyone else respond
so I will share some of my experiences.
The first thing on all Windows systems newer than XP, Right click SPEAKERS
What would a contest be if everything always worked like it did the last
time in the contest.
I use a minimalist RTTY setup:
2 stereo cables from LINE IN/OUT to LINE OUT/IN
AFSK-A with PTT from VOX
N1MM with one instance of MMTTY
Basically, it worked fine, made over 700 Q's. At the urging of
Here is one thing that will cause a similar problem: If you program a
memory while DATA MD is X, then every time you recall that memory you will
be put back into X, regardless of the DATA MD setting prior to the memory
recall. You might have set the memory years ago when using FSK D and now
are
In N1MM - Config - Configure Ports, Mode Control, Audi, Other -
Mode Control ... make sure you have set the RTTY mode to *AFSK*
and not *RTTY* if you are using AFSK.
For more information read the very fine N1MM Logger on-line
documentation.

Yes, what you describes sounds like what happened to me when I switched
to 80 meters. I did have to click the 'reverse' button on Fldigi to
receive properly. Then when I tried to work stations, I got a lot of
'AGN.' I noticed the bargraph displays on the W2 watt meter kept
flashing. I
I am trying to operate AFSK on 15m in the ARRL RU contest. I have 2 contacts in
the last 2 hours. I am by no means a big gun, but I am usually better than
this. Lineup is K3-KPA500-KAT-500. No problems on receive. Drive is set to
produce about 350 watts from the KPA-500. SWR is below 1.5. As
Are you in DATA A mode, or if not do you have compression turned up too far?

I'm no stranger to soundcard RTTY or to my K3, but today I decided to mix
the two and fire up MMTTY on the K3. The first thing I noticed is that
there was a very strange ticking sound in the monitor. While it was
difficult to hear on frequency on another radio, you could hear clicking

Jim,
Thanks. I've seen and read your document previously. Is there something
specific you are referring me to in your document that I already haven't
covered? Let me recap and add a couple points of clarification:
* It's not an RF problem, as it still exists in TX TEST mode.
* I do not have a
Just wondering, why not use the line in instead of the microphone input?

Because I use the same mic input during SSB operation, keeping the
configuration the same regardless of what radio is in that position. The K3
is the only radio that has a line in. And, I did try using the line in to
troubleshoot this problem. Due to the 20dB attenuator that I'm using, I had

Ah! That's a source I hadn't thought of, but it's a perfect

Okay, all good suggestions. Thanks Jim and Joe.
I didn't stop at just removing the RS-232 cable. I removed EVERY cable to
the K3 other than the single cable for audio in. (I kept the grounding
braid and antenna, but still tested using the TX TEST mode, no RF.)
Tried the FP mic connector.
One other thought. Are you using the line out to drive your soundcard?
And if so, is your monitor level turned up on the K3? And if so, is
anything in your computer, digital mode software, allowing the incoming
sound card audio to be mixed with the outbound audio? Each software

All cables were removed, other than the LINE IN into the radio, including
the line out. Headphones were worn to listen to the monitor audio. (Okay,
so I didn't mention the headphones, but they are electrically isolated from
everything else.)
