Re: [Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Gordon LaPoint

Ralph,
I normally use MMTTY, with DXLabs.   That is not the problem, the 
Mark output of the radio is at ~200hz, NOT 2Khz as normal, and can not 
tell if the space is there or not, due to the super low frequency offset 
from the dial frequency.   I'm setup for SO2V operation with Writelog, 
that also has the problem.  I did check for port conflicts and did not 
find any.

Thanks for the suggestions!

Gordon,
 How are you generating FSK and are you using MMTTY?  It sounds like 
you are getting PTT but not FSK out of the serial port. There may have 
been a conflict pop up in your PC for that serial port. I have had the 
exact problem using MMTTY through MH Digi Keyer & Digi Keyer II.

[Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Gordon LaPoint

Hi All,
This weekend my K3 stopped working with FSK.  AFSK works just 
fine.   I have ran many RTTY contests with the K3 in FSK mode, using 
various software drivers.   The problem is I get a single tone, but at 
the wrong frequency, Its about 200hz, not 2125Hz.  I checked the pitch 
setting, its still setup for High tones, the radio keys just fine, I 
have not checked the fsk input signal, but even if that was bad and not 
toggling I should still have an output at the Mark frequency, not way 
low at ~200hz.
I reloaded firmware, - no change.   The K3 is a mid 5000 serial number 
and has worked flawless for many years of RTTY contests.
This one has me baffled, any suggestions?   (I switched to AFSK 
setup for now).

Re: [Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Ed
If you are using MMTTY make sure that you have the "EXTFSK" patch set up 
in both the TX setup window and the Misc window.  I get tripped up on 
this every once in a while.  If these settings are correct you probably 
have a physical problem with the FSK keying lead between the interface 
and the K3.  You can check the radio by grounding pin 1 of the ACC 
(DB15) connector.  The tone will shift when grounded.


Good luck
Ed

Re: [Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Richard Ferch

Gordon,

It's not clear what you mean. The mark output from the radio is at RF, 
not at either 2 kHz or 200 Hz. Do you mean the audio monitor tone you 
hear from the K3, or are you monitoring in some other way?


In FSK D (and also in AFSK A), the K3's dial displays the actual Mark 
frequency as transmitted. If you are monitoring via an external 
receiver, the two RTTY frequencies should be at the K3's dial frequency 
(mark) and at a frequency 170 Hz lower (space).


The audio monitor tone from the K3 should be at the K3's Pitch setting. 
If it isn't, that would seem to point to something odd in the monitor, 
which does not necessarily mean there is anything wrong with the actual 
transmitted RF.

Re: [Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Gordon LaPoint

Rich,
 Sorry, I am going by the monitor tone.  I need to check the actual 
rf on another radio and see if the Mark is really at 200hz offset or at 
2.1Khz like it should be ( I use high tones from mmtty or 2tone)

the AFSK A is working normal.  I did not hear any shift using FSK D.
I normally use FSK D, and the "pitch" setting was still correct, is 
there another setting that affects the pitch?

Re: [Elecraft] K3 FSK RTTY Problems

2015-11-09 Thread Gordon LaPoint

Rich, and others on the list,
Thanks for all of the suggestions.   I got the system working.   
The problem was the pitch setting.  While in FSK D If you hold the Pitch 
button the K3 shows the current pitch, (2125-170) is what was showing.   
I changed it to low tones (915-170) and back to 2125.  That fixed it!  I 
now have working FSK-D mode again.  I'm not sure what was going on, but 
the pitch was at some value of ~200hz, not 2125.  Resetting the pitch 
fixed it.  So for future reference, don't believe the display, change it 
and then set it back to what you want!!  I was hearing a tone of about 
200 hz when going into tx, but was hearing the 2125 when I pressed the 
Pitch button.  Now I hear a tone of 2125 and diddles when I use the 
software to send something.


Thanks to all for the suggestions,

Gordon - N1MGO

Just a thought - is there any chance your K3 is not in FSK D, but in 
some other Data sub-mode?


When I put my K3 into FSK D and press the XMIT button, I hear a 
sidetone in my headphones that is identical to the tone I hear when I 
press the PITCH button. (That's assuming I don't have the K3's MON 
level set to zero.) The pitch of the sidetone is affected by the PITCH 
setting, but nothing else I adjust, including filter settings and 
XIT/RIT, seems to have any effect on it.


In PSK D, the sidetone is a PSK idle signal at 1000 Hz. In AFSK A and 
DATA A, there is no sidetone unless there is audio getting into the 
radio (e.g. from the Line In connector).


It has been years since I used FSK. I switched to AFSK soon after I 
got my K3, as soon as I realized that the K3's transmitted signal was 
cleaner in AFSK than in FSK. However, back when I did use FSK, when 
there was a keying input connected to the ACC connector sending 
diddles to the radio I heard diddles in the monitor, the same as I 
would in AFSK where the input to the radio actually is a diddling 
audio tone.


If you are hearing a 200 Hz tone (lower pitched than even the lowest 
possible CW sidetone) with the radio transmitting in FSK D, there is 
something very peculiar going on; that's not the way it is supposed to 
work.


If you are hearing a steady tone in the monitor at the Pitch frequency 
with no diddling, then either the software is not generating a keying 
output (MMTTY set up for AFSK instead of FSK, for example), or the 
connection to the ACC connector is broken.


You can use the K3 Utility to check some of this. Start the Utility 
up, choose the Terminal tab, select RTTY, put the K3 into FSK D, type 
something into the lower pane near the bottom of the window, press 
Ctrl+T or click on the Transmit button, and you should hear something 
that is mostly at 2295 Hz (the space tone), with diddles and text 
characters causing it to diddle back to 2125 Hz (the Pitch setting). 
If that works, then the problem is likely somewhere outside the area 
that the Utility tests.


You can test for a problem in the K3's internal wiring to the ACC 
connector by shorting pin 1 to pin 5 on the ACC connector to see if 
that causes the sidetone to shift frequency. If that works properly 
but you are not getting the same frequency shift when you try to use 
your RTTY software, then the problem is upstream - in your cable or in 
the configuration of the software you are using for FSK.

[Elecraft] [K3] FSK RTTY Problems

2014-02-10 Thread Jim Miller
Similar to others I had major problems with FSK-D RTTY with the latest beta
firmware this weekend on my K3 #1210.

I often found that my K3 didn't appear to recognize on the first attempt on
a band that the KPA500 was even present at all and instead put out the full
100W that I normally run when not using the KPA500. I hadn't seen this
reported by others. Needless to say the KPA faulted immediately on that!

I never really found a repeatable sequence that would set the power. I had
seen the note that power changes in TX or RX could be different so I
frantically tried either after reducing power into the teens after the KPA
faulted to huge overdrives.

I eventually found settings on each of 10 thru 80m that were somewhere
between 400 and 500w but never felt comfortable that something wasn't going
to go nuts.

FWIW, I normally run 500w or a bit more on RTTY with no problems at all
prior to this beta.

Eagerly awaiting a fix!!!

Of course...

Was just adding to the info. Including the bit about the K3 not honoring
the internal tables for KPA500 being attached.

Re: [Elecraft] [K3] FSK RTTY Problems

2014-02-10 Thread Wayne Burdick
Jim,

I have a newer field-test release, 4.83, that fixes the primary problem of 
power-setting in RTTY mode (FSK-D). While I still have little more work to do 
to get power to settle quickly, 9 out of 10 ops testing 4.83 said it was 
working well enough for their needs. (Definitely fixes the problem from 4.81, 
which was *also* tested by a lot of ops, but they all missed this problem 
somehow. That's why we do beta before production….)

I'll send you a copy.
