Re: [Elecraft] [K3] RTTY Questions

[Wes]

Are you using an external RTTY program, e.g. MMTTY?  If not and you're using the 
internal CW to RTTY feature, I can't help you.  Otherwise I'm assuming audio 
input via Line In.  Baud rate is set in the program.


Make sure the audio drive, set by 1) soundcard level and 2) "Mic" gain, drive 
the ALC indicator to four bars.  Less and the power control loop will try to 
adjust, but it does this slowly. Otherwise it could be a blown final, in either 
of the PAs (regrettably too common) or a mistuned BPF.  I don't know how common 
this is but it happened to mine.

You may have lost a final.  How to confirn (TNX WE6R):

1. Mode: SSB
2. Band: 160m
3. Power: 10W
4. Speak into the microphone and listen on another receiver.
5. Continue speaking while listening on the other receiver and slowly
increasing the power.
6. If the received audio becomes terribly distorted once you get above 13
or 14 watts, it usually means that you need to have the unit repaired to
replace a final.

GL.

Re: [Elecraft] [K3] RTTY Questions

[Ken K6MR]

My radios only do the power ramp up the first time you transmit after changing 
bands.  Doesn’t take that long though.  Less than one second I would guess.  As 
noted, it’s the power control loop.  Usually it’s not that noticeable.

[Elecraft] [K3] RTTY Setup: Solutions

[John Reilly]

Here are the solutions to my questions:
1. FSK/AFSK Mode - The solution was to set the RTTY mode in N1MM to AFSK

2. Intermittent failure to go to receive after transmit: There are at 
least three ways to setup the K3 and N1MM for RTTY AFSK PTT:

    a. Use Serial RTS for PTT
    b. Use "PTT via Radio Command Digital Mode"
    c. Use VOX
Note that you cannot use more than one of these at a time. FWIW, my RTTY 
N1MM macros do have {RX} at the end of each line.
The first two did not solve my problem -- I still failed to return to RX 
about a third of the time; however, VOX appears to have fixed the 
problem. I wish I knew why the first two don't work.


This is probably applicable to WSJTx PTT, too.

Thanks to those who replied,

Re: [Elecraft] [K3] RTTY Setup

[Peter Lock]

Hi John, experienced this once or twice myself.  There is a setting in N1MM+
to check.  From the N1MM+ log entry window, select Config, Mode Control and
in the combo box against "Mode RTTY" select "AFSK" for the appropriate
Radio/VFO. That may also resolve your hung PTT; VOX should then work.

Good luck

Peter

I've recently changed from FSK to AFSK, and having issues. FWIW, I am 
using N1MM with 2Tone as my RTTY interface, with the K3 internal sound card.

First, When I go to DATA MD, it is always set to FSK D. I reset it to 
AFSK A and it works; however, if I change bands, it resets itself to FSK 
D. The AFSK A setting does not "stick" - is there a way to make the K3 
remember this setting?

Second, the K3 is staying in Transmit after the RTTY message is 
finished. I usually have to press the XMIT button to return to receive. 
I do not have anything setup in the 2Tone PTT box, which I suspect is 
the problem. I tried to use the serial DTR, but 2Tone was unable to use 
the serial port that N1MM was using. I also tried VOX, but did not see a 
difference. Any suggestions for setting up AFSK PTT?

Thanks,
   - 73, John, N0TA

[Elecraft] [K3] RTTY setup

[Paul Antos]

These are N1MM + questions. The mode selection is in the N1MM / MMTTY  
configuration.

The hanging PTT is from multiple instances of PTT asserted. I had this problem 
with my IC-7610, but I had too many PTTs in the configuration.

N1MM documentation should contain specific documentation for setup with any 
popular rig. That's the place to go.

Re: [Elecraft] [K3] RTTY Setup

[Joe Subich, W4TV]

1) Are you changing bands on the rig or by using N1MM+?

  a) If "rig" - Data Mode is stored by band.  Change it on each band.
  b) If "N1MM+" - be sure to set "Digital Modes" to AFSK

Second, the K3 is staying in Transmit after the RTTY message is 
finished. I usually have to press the XMIT button to return to

receive.

Assuming this is with N1MM+ - set the rig port to allow Command PTT for
digital and make sure all your messages end with the command to return
to receive (%E or %R - I'm not sure and not in front of N1MM).

[Elecraft] K3 Rtty

[Larry Boekeloo]

I've been running my K3 and my RIg Expert TI-5 for several years with no

PTT ERR after unkeying in RTTY mode.
Any ideas?

[Elecraft] K3 RTTY Decode

[Hank Garretson]

Good friend K1GQ wondered out loud about real data comparing K3 RTTY decode
to software decoders. Here is fifteen minutes of real data.

Attachment 1. K3 decode captured by K3 Utility program. K3 width 400 Hz.
Didn't fiddle with K3 decode parameters--used factory defaults.

Attachment 2. MMTTY decode. AA6YQ FIR512 profile for first five minutes,
them Fluttered Signals (FIR) profile for last ten minutes.

If attachments didn't make it to list, email me and I will send them to
you.

Data captured during first fifteen minutes of 18 March zulu NCCC RTTY
Sprint.

Used MMTTY cross bars to tune.

The sometimes frantic NS is a good test with lots of frequency changes,
great signal-strength variability, and QRM.

My take is that MMTTY is superior to K3 decode, but I was pleasantly
surprised by how well K3 decode performed.

My work is done. I'll leave it to others to draw more rigorous conclusions.

Regardless of relatively decode performance of K3 versus MMTTY, I believe
the most important plus of MMTTY and similar programs is call and exchange
parsing, highlighting, and clicking into log window.

When contesting, I have one MMTTY window and two 2Tone windows open and I
constantly scan all three. My experience is that sometimes MMTTY is better,
sometimes 2Tone Flutter is better, and sometimes 2Tone Selective is better.
I often end up integrating bits and pieces from all three windows to
complete a contact. That's part of what makes RTTY contesting fun. Your
print may vary.

Re: [Elecraft] K3 RTTY Decode

[Kevin Stover]

I don't know where the idea started that the decode algorithm in the 
K3(s) would be a good as a stand alone dedicated program like MMTTY. It 
won't ever be simply from a processor and memory point of view. I'm sure 
the Elecraft principals have made no such claim so why do people still 
expect it?


It's a "gee whiz would you look at that" kinda thing more than anything 
else. Use it in a serious contest or DX pileup? Nonsense. Let the 
computer/software do what it does best and let the radio do what it does 
best.

I virtually always do RTTY with MMTTY and 2Tone, but I also watch the K3 
decoder, and find it to quite good.

Re: [Elecraft] K3 RTTY Decode

[Wayne Burdick]

We included RTTY/PSK decode/encode in the K3/K3S/KX3 to expand the range of 
conversational, no-PC-required digital modes available to the operator. I'm 
glad that our high-efficiency, convenient implementation suffices for many QSOs 
and casual contest operation.

If the communication requirements are more demanding and a PC is 
available...well, there's always LINE IN/OUT :)

[Elecraft] K3 RTTY NO DVR message on memory

[Joe Moffatt]

When using RTTY, usually I can hit M1 to give my callsign like in CW mode

But today that quit working, but it still works in CW mode Anyone have any

It displays NO DVR when I do that.

Re: [Elecraft] K3 RTTY NO DVR message on memory

I'll answer this myself... I just found via google another had the same problem.

In my case, the mode on that band was set for AFSK A , not FSK mode.  The M 
keys only work on FSK as far as I can tell.

[Elecraft] K3 - RTTY Mark frequency not at 2125, as set (FSK)

Disregard my earlier post - was a case of being upside down.

(Now I know where to find it: CONFIG: FSK 0=inverted; 1=correct.)

[Elecraft] K3 - RTTY Mark frequency not at 2125, as set (FSK)

[conwell]

I tried setting up FSK rtty today for first time in a long while, and 
found I had a problem.


I have a pair of K3 rigs on the desk.  No trouble with one.  On the 
other, Mark tone is sent higher than 2125.  (It's high enough up that my 
2d rig can't decode the TX signal.  Maybe around 2600 Hz)


The Space tone may be high too - my ear can't discriminate.  (But in the 
X-Y scope pattern of the TX signal, as received on the 2d rig, the tones 
are at right angles - if that means anything...)


Thinking it might be a TX AFC problem, I disconnected the computer.  
Same result.


When I long-push PITCH, the rig speaker gives the 2125 HZ tone.  But 
when I touch XMIT, the rig gives a different - higher - tone.  (In 
contrast, with the other K3, both buttons yield the same tone - a tone 
which matches the 2125 Hz output by the problem rig when I press its 
PITCH button).


I tried updating all firmware (e.g., from 5.10 to 5.35).  But issue 
persists.


Ideas?

Thanks,

/Bill, K2PO

Re: [Elecraft] K3 RTTY Message Button Diddles

[Jim N7US]

Unlike Yaesu radios I've had, I've never had to change the polarity of my K3
or any program, including MMTTY, to reverse for FSK (FSK D in the K3).

73, Jim N7US



-Original Message-

Robert,

that's wrong. Using push buttons/memories from the K3 frontpanel all the
time on FSK-D if I just need to send my call and a report to work some DX.
No need to start RTTY on the PC then. ;-)

If I use the PC for RTTY (MMTTY in my case) there's no need to change
something. Either configure your RTTY software for reverse polarity if you
want to leave the K3 default or simply change the K3's POL in the menu (I'm
on the road right now but sure there is a menu option). K3 memories or doing
RTTY with paddle will still work fine!

Record an IM (no letter space) character at the end of the message.
If using the K3Utility to enter the message text, end it with | and 
that message will work fine for CW, RTTY, and PSK.

Re: [Elecraft] K3-RTTY-No Diddles

[Don Wilhelm]

Paul,

Make a test connector from a DB15 connector - so you can manually short 
between pin 1 and pin 5 - do not connect the Microham supplied cable.
Start the 'send' process, listen for the single tone, then short between 
pin 1 and pin 5 - the tone should change.  If it does, than the K3 is 
OK, look for the problem in the Microham box or the cable.

If the tone does not change with that test, contact Elecraft support.

--Paul,

Details on how you are connecting the DKII FSK output to the K3 please.

A quick perusal of the DKII information indicates to me that the FSK
output is from a computer COM port - which to me indicates that it is
RS-232 levels.
Those RS-232 levels must be converted to TTL levels by a one transistor
keying circuit and the output of that circuit applied to the K3 ACC
connector pin 1.

The fact that you have a single tone indicates to me that you do not
have anything connected to the K3 ACC connector that will pull pin 1 to
ground.  That means that the K3 will generate the space tone, but there
is nothing to tell the K3 to change the tone to a mark tone.

Re: [Elecraft] K3-RTTY-No Diddles

[Mike Harris]

Paul,

I have used the microHAM digi keyer II with the K3 and MMTTY within 
Logger32 and using the K3 cable BD15-EL-K3.  There are detailed 
configuration documents on the microHAM web site for a variety of 
applications.


You do not need any level changers.  It is all done in the DK II.

When I bought a new PC the on board sound was perfectly good and I 
removed the DK.  For me AFSK works fine with just a couple of audio 
leads and with PTT over the RS232 interface.


Regards,

Mike VP8NO

You are stating that you are trying to use FSK.  MMTTY requires EXTFSK 
to be added to the MMTTY folder for it to be functional for FSK.  Also 
EXTFSK needs to be configured.  A small window will appear showing the 
lead assignments.  These must agree with the com port assignments 
associated with the USB Router.  EXTFSK is available on the MMTTY Web 
Site, just scroll down the MMTTY page and you will find where to 
download it.  The page also has an excellent explanation on how to use 
EXTFSK.  In addition make sure you have the K3's data mode set to FSK 
D.  Should work, works for me.

Re: [Elecraft] K3-RTTY-No Diddles

[Ed Muns]

EXTFSK is only required if a USB-Serial interface is used which doesn't have
an adequate UART implementation to support 45 baud and the 5-bit code.  The
Digi International Edgeport/4 and /8 interfaces work fine without EXTFSK.
The microHam interfaces also work fine without the EXTFSK module.

Absolutely incorrect with microHAM microKEYER II and Digikeyer II.  Both
interfaces provide a UART interface that works like a COM Port capable
of handling 45.45 baud.

Please see the example configurations for MMTTY with MK II and DK II in
the MK II and DK II sections at www.microHAM-USA.com/support.html.

[Elecraft] K3-RTTY-No Diddles

[paul ecker via Elecraft]

Ihave a K3 (entire K-Line). Win 7 PC 3.5ghz processor 16gb ram; MicroHam DKII 
Interface. Withthis setup I am able to successfully do PSK31 using HRD-DM780, 
WSJT-X andJT65HF, WSPR and run N1MM+ successfully in SSB and CW - both RX  TX. 
Myproblem is with MMTTY both running byitself or as the engine in N1MM+. I can 
receive just fine but when it comes to transmitting,all seems to work well- but 
I  get no diddles. The mode is FSK. Better said,when MMTTY goes to Tx, I get 
a red Tx  light on the K3, a solid green PTT and aflashing  green FSK light on 
the DK II  but I hear a Solid Tone fromK3 audio and No Diddles. I have also 
tried RTTY using DM-780 and get same result, no diddles. I have contacted other 
K3/MicroHam/DK II users who aresuccessfully using MMTTY and compared 
configurations, but found no differences.I have contacted MicroHam tech support 
and ran some tests suggested by them but found no problems with the interface. 
So I am wondering if there may some item in theK3 configuration that I have 
missed that is leading to No Diddles.If needed I can get into further detail 
on MMTTY  DK II settings, orcurrent K3 configuration. I did not include in 
this posting for brevity sake.  Hope someone can help me solve my Diddleissue.

[Elecraft] K3-RTTY-No Diddles

[paul ecker via Elecraft]

Don - The Output of DK II is connected to the K3 ACC port using a DB15-EL-K3 
cable supplied by microHam with the DK II.
73 Paulkc2nyu
--Paul,

Details on how you are connecting the DKII FSK output to the K3 please.

A quick perusal of the DKII information indicates to me that the FSK 
output is from a computer COM port - which to me indicates that it is 
RS-232 levels.
Those RS-232 levels must be converted to TTL levels by a one transistor 
keying circuit and the output of that circuit applied to the K3 ACC 
connector pin 1.

The fact that you have a single tone indicates to me that you do not 
have anything connected to the K3 ACC connector that will pull pin 1 to 
ground.  That means that the K3 will generate the space tone, but there 
is nothing to tell the K3 to change the tone to a mark tone.

73,
Don W3FPR

Peter

I have it working now, thanks

But I connected LINE IN and OUT from K3, directly to my computer, and is 
transmitting

So the problem I have with the TASCAM US-144 MKII is that I don´t know where to 
connect this cables on it :-)

I have them connected to LINE IN and PHONES (that use 3.5mm connectors) but 
didn´t TX

So now if someone that use TASCAM that can help me to know where to connect the 
cables

Line out from K3 to Tascam line in.  Line in from K3 to Tascam line out or 
headphones.  Only connection from Tascam to computer is USB.

My experience with Tascam was you MUST update both Tascam driver and Tascam 
firmware from Tascam web site before it will work properly.

Hello Jorge,

How do you put the K3 in TX mode?  There are two ways -- VOX or via an 
additional serial port?  I use VOX. To use VOX is pretty easy. Set 
levels according to my applications note.


http://k9yc.com/USB_Interfaces.pdf

Set the K3 for AFSK-A. Set the RTTY tones in MMTTY and the K3 to the 
same frequency, and make sure both are set to 45 baud.


In MMTTY, select your Tascam sound card for both TX and RX. Also, in the 
MMTTY Options Tab, select left or right channel for RX, depending on 
which channel the radio feeds.


Feed audio from the Tascam to the Line Input. Follow instructions in the 
K3 manual to set the Line Input control. The Mic Gain becomes the Line 
Input control in digital modes.


To set the VOX, put MMTTY in TX mode (send anything) and adjust the VOX 
gain until the K3 goes into TX.


This is not exactly step by step, but it covers most the things that can 
prevent you from transmitting. :)


73, Jim K9YC

Re: [Elecraft] K3 RTTY-CW Help

[Phil Anderson]

Steve:

I too am a new owner of a k3 kit and just got it going couple of weeks 
ago. You will enjoy this radio. I too will be looking at N1MM, etc

so can operate via keyboard part of the time during contests.

In the meantime, regarding RTTY, why don't you try using your CW paddle 
to send and the readout on your K3 panel (VFO B area) to receive the 
RTTY first. You will not need any added equipment. Here's how to do it 
roughly:


1. Read pages 31 and 32 on your owner's manual. Here's a bit of the text:
You don't need a computer to get started with data modes on the K3: it 
can receive and display RTTY and PSK31 on its LCD screen. You can 
transmit in data modes using your keyer paddle (see page 34).


2. I made my first contact with a W1AW/x station last weekend - and it 
was a split connection at that - way cool, that is, I transmitted UP 1 
kHz per his CQ call.


3. Doing this experiment will really enhance/check your code sending 
too. Use the TEST mode and practice sending code in the above mode and 
check in the LCD (vfo b area) that your ending is accurate enough for 
the K3 to decode what you send in RTTY. The K3 converts that CW 
internally and transmits the RTTY for you. You'll improve your code and 
make your first RTTY contact in the same experiment!


Happy New Year,

Uncle Phil, W0XI, DCARC, 4SQRP, Lawrence, KS

Here is another link with step by step instructions for N1MM and MMTTY.

Also, AA5AU's is still there, he has done a major rebuild and if you just
snoop around, you'll find what you need.

[Elecraft] K3 RTTY PROBLEM

[Bert via Elecraft]

I tried to get on the OK DX RTTY contest this weekend using my K3. I used  
N1MM+ with MMTTY and configured MMTTY as usual. Hit the TX button in MMTTY, 
the  K3 went into transmit mode with no output!
I'm using FW version 5.01 on the K3. 
I eventually resolved the problem, but don't know the reason for it! What  
happened is this: in MMTTY Config, I set the Mark (and HAM Default) 
frequency at  2125 Hz, as I've always done. No r.f. output from the K3 with the 
PC 
(and  interface) putting out the RTTY signal...
The solution was to set the Mark (and HAM default) frequency to 915 Hz (170 
 Hz shift, of course!). That worked! 
I swear I NEVER touched the PITCH button, never mind that I had never  
changed the Mark frequency there...BUT, there it was, big as life, 915-170! Did 
 
this parameter change on its own from 2125 to 915, or did this change take 
place  with FW updating? 
Curioser and curiouser... as Alice would say!

Re: [Elecraft] K3 RTTY PROBLEM

[Don Wilhelm]

Bert,

I suspect that you did not have the K3 mark frequency set to match that 
which was set in MMTTY.  The PITCH button will allow you to change the 
K3 mark frequency to match that used in MMTTY.

[Elecraft] K3 RTTY

[Terry Burkholder]

Is there any way to use tones other than 2125 to receive RTTY signals? I 
can no longer hear frequencies that high. I know the FT-1000 MP has  a 
menu option to select lower tones for RTTY RX. I can't find any menu 
option in the K3 that allows you to change the RX tones.

Sure.  Use the Pitch control.

Be sure to make a commensurate change in the RTTY program; both TX and RX.

[Elecraft] K3 RTTY Help

[Steve Lett]

I was trying to set my K3 for RTTY. By changing the menu settings, somehow
I have put my K3 in transmit mode and now cannot change the VFO B or A Menu
or Config settings to get it to stop transmitting. I turned the K3 off but
when I turn it on, it goes into transmit mode. What can I do to get my K3
out of the locked transmit mode? Thank you.

Re: [Elecraft] K3 RTTY Help

[Bill Frantz]

It sounds like what ever system you are using to key the 
transmitter isn't letting go. Please provide more details about 
your setup. Are you doing RTTY with the K3 alone, using CW 
paddles to send? Are you using a sound card to process the audio out?

Re: [Elecraft] K3 RTTY Help

[Don Wilhelm]

Steve,

The problem source may be in something related to your external setup.
Remove all connections from the K3 - does it behave normally?
Then add back the external connections one at a time to see which one 
creates the problem.

[Elecraft] K3 RTTY 4 Second Delay

[Brian F. Wruble]

I am sure this has been asked and answered, so sorry...

Is there any way to truncate the 4 second delay when operating the K3 in
 RTTY in FSK-D mode.  The carrier stays on 4 seconds after the last
character has been sent.  Is there a setting to reduce that?  Is there a
keystroke or character to send that will signify end of transmission and
cause TX  RX?

I believe there is a CW character that will do it, but I don't always have
a paddle with me when operating the K3 remotely using the K3/0 mini.

Thanks.  73 de Brian W3BW

Send ..-- (IM pro sign, with the I and M concatenated). You can think of it 
as IMmediately terminate transmission.

If you have trouble sending this character, trying thinking of it as sending 
the number 2, but leaving off the last dash.

Re: [Elecraft] K3 RTTY 4 Second Delay

[Wayne Burdick]

The IM prosign can also be inserted at the end of CW/DATA messages using the 
message editor in K3 and KX3 Utility. I believe it's the | (pipe) character. 
This character is not sent on the air when it appears in a message memory, and 
in DATA mode it is not sent at all, even when inserted live by the keyer 
paddle.

[Elecraft] K3 RTTY spectrum

[Kjeld Holm]

For the RTTY people,
You may all know already but I did not - therefore this info.
In ARRL National Contest Journal September/October 2013 issue on page 3 to 7
the article RTTY Spectrum Measurement is discussing bandwidth issues and
other issues regarding transmission of RTTY. For the ones of you who have
access to this publication: Read it. For others the conclusion is as I read
it: Switch on the AFSK TX filter in the Config menu (page 53 in the K3
manual).

Not true!  If one is running AFSK *always use AFSK A* and set
CONFIG:AFSK TX = FIL On.

The AFSK TX Filter cleans up any hum on your sound card from bad
connections, grounding issues, or distortion from over drive.  However,
with the K3 one can get the same narrow transmit spectrum by using FSK
without the issues of AFSK.

Re: [Elecraft] K3 RTTY spectrum

[Joe Subich, W4TV]

 Essentially AFSK will need to be used the same as FSK, tuning not
 mousing.

As it should be ...


With AFSK TX = FIL OFF you can wander around the waterfall if you
wish. Not necessarily the best idea for the reasons given by Joe.


Among other reasons for *not* using wideband transmit and mousing
around the waterfall, take a listen to some of the signals on JT65
or JT9 ... many of them have high levels of broadband noise from
their sound cards that may be only 15 or 20 dB below the tone.
That noise is also attenuated significantly by the AFSK TX filter
resulting is a much cleaner signal (and significantly less QRM).

On 2014-06-09 10:52 AM, Mike Harris wrote:

Not a universal truth.

The AFSK TX filter is centred around your selected tone (pitch)
frequency pair.  You will have to tune each RTTY signal you wish to call
with the VFO.  Meaning you cannot leave to K3 tuned to one frequency and
wander around the waterfall picking off stations by using for example
the MMTTY NET function.  It only takes around +/- 300Hz offset from the
normal tone pair and your TX output has gone, evidenced by loss of RF
output and a vanished ALC reading.  The K3 knows nothing about the
actual tone pair being passed to it other than what we tell it.

If I remember correctly the NCJ article showed that at the the time of
writing the K3 AFSK TX spectrum was cleaner than that of FSK.  I believe
it also mentioned that Elecraft was tweaking the waveform to improve the
FSK spectrum.  I no longer have the article so cannot confirm this and
apologise if this statement is incorrect.

Re: [Elecraft] K3 RTTY spectrum

[Kjeld Holm]

The AFSK TX Filter cleans up any hum on your sound card from bad
connections, grounding issues, or distortion from over drive.  However, with
the K3 one can get the same narrow transmit spectrum by using FSK without
the issues of AFSK. Written by Joe Subich, W4TV

Not as I read the article - but I may be wrong. 
 Effect of the K3 AFSK Transmit Filter
Rather than hacking the K3 to transmit
through a narrow roofing filter, an equal or
better result can be had by simply enabling
the AFSK transmit filter in the configuration
menu. This places a 400 Hz filter before
transmit audio arrives at the RF modulator
(this only applies to AFSK-A mode,
not DATA-A mode). This filter is centered
around the tones configured under the
radio's PITCH menu. The effect is similar
to what MMTTY and other programs do in
their software, but this is done in the radio's
DSP firmware.
The radio's manual says this filter can
serve to filter any noise that might be on
the audio input, and it certainly will do that,
but it has the additional benefit of filtering
keying sideband energy. Figure 9 shows
the result of MMTTY's unfiltered phasecontinuous
AFSK audio into the K3 with
the K3's AFSK filter enabled. Comparing
Figure 9 with Figure 3 demonstrates the
effect of the K3's AFSK filter, as both have
exactly the same audio input to the K3.
Attempts to overdrive the radio resulted
in no significant change in signal bandwidth.
Even when transmitting wideband
noise into the K3, the AFSK filter limits the
bandwidth. While it is possible to transmit
trash that is difficult or impossible to copy,
the K3's AFSK filter makes it unlikely that
it would generate much interference on
adjacent channels.

An important point: Even given the K3's
transmit IMD, the occupied spectrum using
shaped FSK is much narrower than
that when using the internally generated
FSK synthesizer. FSK keying sidebands
are not unique to the K3; every radio that
uses phase-coherent for its internal FSK
generator will generate a wider spectrum
at essentially any power level. The only
differences will be in cases where the IF
filter cuts off the sidebands.
As an experiment, I decided to see
just how wide I could make my signal by
overdriving the K3's line input. I cranked
the PC's headphone output to 100 percent
and drove the ALC as hard as I could by
setting the line input gain to maximum (see
Figure 7). Some strange spurs show up in
the spectrum, but even those are below the
keying sidebands of the FSK transmitter
(see Figure 2). Even trying to transmit absolute
trash I wasn't able to make the AFSK
Figure 4 - AFSK with MMTTY using a 512 tap TX BPF with a
passband of from 2000 to 2400 Hz, 0 dBm
Figure 5 - AFSK with MMTTY with 512 tap TX BPF, 100 W
signal as wide as that of the internal FSK
generator. The rise in the noise floor over
the 2.8 kHz bandwidth occurs, because the
K3 amplifies noise from somewhere; at this
gain setting it is present whether or not anything
is plugged into the K3's line in jack.
This behavior is almost certainly specific
to the K3, because the K3 scales audio in
DSP before it ever enters the RF stages.
Other radios are not going to protect you
from yourself nearly as well, so you might
expect harmonic distortion and other bad
things with no limiting prior to the point of
RF modulation.

Re: [Elecraft] K3 RTTY spectrum

[Joe Subich, W4TV]

 Not as I read the article -

The article was written before the latest update to the K3 FSK
generating DSP code in MCU 4.66 released 2013-03-22.  The article
is simply out of date.

The release notes for 4.66 say:

FSK-D KEYING BANDWIDTH GREATLY REDUCED:  This change reduces the
amplitude of the FSK-D keying sidebands by 25-30 dB at 500 Hz
offset, giving teh K3 one of the cleanest FSK signals available.


The author of the NCJ article reviewed the K3 firmware while it
was still in beta here: http://www.frontiernet.net/~aflowers/k3beta/
The author's own web page contains the information in the NCJ
article here: http://www.frontiernet.net/~aflowers/k3rtty/k3rtty.html
By comparing the before and after spectrogram in the K3beta article
with the before, 2-Tone, and filtered MMTTY spectrograms on the
AFSK Bandwidth with waveshaping page in the original article, you
will see that the new K3 FSK code is every bit as clean as the wave-
shaped AFSK *without* the problems associated with AFSK.

Note that the author's article on the web page shows the benefits of
the K3 AFSK TX filter in terms of being able to clean up all manner
of *intentional* abuse to the AFSK audio - abuse that would render
the AFSK signals from other transceivers an absolute festival of QRM.

Here is what the author wrote of the new FSK code:

Notice that the unshaped [original - W4TV] keying has clicks that
will result in an S7 noise floor at 500 Hz spacing that very
gradually flattens out to an S4 noise floor 1 KHz each side of
transmitter, which is eventually limited (we hope!) by the IF filter
in the transmitter. This makes it easy to see how loud signals
placed every few kilohertz raises the noise floor of the entire band
for everyone.  The BW-reduced [new code - W4TV] signal is under S2 at
500Hz and drops off very rapidly into the noise as one tunes away. It
is below the S1 noise floor of the receiver when tuned more than 700
Hz away.

Fred,
If set correctly, there's no difference.  However, FSK is foolproof.  It
can't be overdriven with excessive audio input resulting in excess bandwidth
and spurs.  Some of it is historical, as in some older radios, narrow
filters cannot be used in AFSK mode.

Re: [Elecraft] K3 rtty decode vs: computer decode

[Fred Jensen]

Well ... I'm not sure FSK is actually foolproof, based on the number 
of posts to this list about problems getting FSK running using various 
external interfaces.  It is true that AFSK is Audio in/out and can 
overdrive things, not easy in a K3 but certainly possible.  Even cheap 
sound cards deliver essentially pure sine wave audio, the better ones do 
even better.


One should never underestimate the populations' ability to screw up any 
technology, but beyond that, and assuming that two hams are equally 
smart and equally adept at setting their gear up, is there really any 
discernable difference between the two methods with a K3?  I think 
that's my root question -- What is it about direct FSK that makes folks 
want to go to lengths to get it working?  And, I'm not so sure that 
direct FSK in a K3 is what it was in a T-368 45 years ago.


I grant that with older rigs, carrier and opposite sideband suppression 
could, being generous here, be questionable, and the AFSK result would 
not be pretty.  But that was a long time ago and we're talking about 
K3's now.

Not quite.  I've measured audio distortion at -30dB re: carrier for a 
reasonably OK laptop sound card just below clip. That means you have 
spurs only 30 dB below your signal. Not very good. Distortion (and thus 
those sidebands) drops by 10 dB re: carrier if you reduce the output 
level by 6 dB (half the voltage). My measurements are of the audio 
coming out of the sound card.


But I do agree that carefully generated AFSK is just fine, and that's 
what I've always done.

I have to agree with Barry.  For a modest amount of code space (Flash  
RAM), they added a very useful capability for the casual or field  
operator.  I once worked a DX RTTY station via FSK-D mode with paddle  
keyboard.   I could not have done that QSO any other way at that  
time.  The QSO was made more exciting by being on 40 meters, running 3  
watts into an indoor mag loop antenna.  :)

Re: [Elecraft] K3 rtty decode vs: computer decode

[Fred Jensen]

Yes, the K3 certainly allows a multitude of modes, and within each mode, 
several ways of doing it.


I'd really like to know ... no hidden aspersions here ... what the 
difference is between direct FSK and AFSK.  I use AFSK with two 
RadioShack stereo cables between the laptop and the radio.  N1MM with 
MMTTY for contests, or one of several other sound card-friendly programs 
for PSK and JT65 which I almost never use.


I'd really like to know, I'm not kidding and I'm not casting any 
aspersions on any technique.  My K3 provides for both, my AFSK seems to 
work great and when I look at my transmitted spectrum, it looks like FSK 
should look like.


And this has nothing to do with the number of cables behind the rig, the 
back of my rack is visible as you come into the shack and my wife has 
asked, Why do you call it wireless?

My observations have been exactly thee opposite. I find that when I have

MMTTY is needed to accomplish that. :)


Although I am the new owner of a KX3, I haven't had time to use it much. 
But my neighbor, W6GJB tells me that it's even better than the K3 at 
RTTY decoding.


Lately I've adopted WinWarbler for non-contest RTTY operation, which is

Re: [Elecraft] K3 rtty decode vs: computer decode

[Brian Hunt]

I've found the K3 decode is adequate for casual contacts like W1AW/x when I 
find them. Tuning is a bit touchy and the incoming signal needs to be strong. 
Good for a quickie, though. I use the paddle for xmit. 

73, 
Brian, K0DTJ

 I have played just a bit with the rtty via cw function of the K3 and am 
 curious if my casual observations match those of others. It appears that the 
 K3 onboard decoder takes a back seat in rtty decode ability to a 
 radio/computer/mtty combination. Agree/disagree/thoughts?

Re: [Elecraft] K3 rtty decode vs: computer decode

[Bill Breeden]

Jim,

My observations from a side by side comparison between my K3's internal 
decode and MMTTY are similar to yours.  That being said, the ability to 
decode and then quickly call in RTTY or PSK31 mode when an opportunity 
presents itself using the K3 by itself has been very useful to me.  My 
best confirmed contact in RTTY mode is 9N1AA in Nepal and I would have 
missed him if I had waited to bring up my computer with RTTY software.  
Looking at my log from the point when I started using my K3, I see that 
I have worked and confirmed 75 additional digital mode entities, 
bringing my DXCC digital mode total to 185.  Nearly all of those new 
ones were worked from the front panel of my K3.  I usually don't bother 
to bring up my RTTY software unless I intend to participate in a digital 
mode contest or QSO party.  I wish the K3 had PSK63 mode built in as well.


I don't know if I would feel the same way if I didn't have a P3.  I find 
the P3 an almost indispensable tuning indicator for the digital modes.

Bill - NA5DX

[Elecraft] K3 - RTTY keying quit - FSK D

[Pfizenmayer]

Worked RTTY fime Thursday night - started to work a W1AW on RTTY last night and 
PTT was working but  only carrier no FSK. Using direct FSK not AFSK.

 FSK D confirmed on menu. Shorting FSK pin 4  to ground - no freq change -  
open circuit voltage on pin 4 about 3.6 volts but source impedance VERY high - 
I can pull it way down with just leakage of my fingers on the connector .Pulled 
connector and checked DCR from the RCA jack dongle I made  for PTT, KEY OUT , 
AUX , and FSK and shows solid connection to pin 4. 

Did an EEINT and put in previous config setup - no change - did another EEINT 
and put in current setup - no change. 

Am still crosseyed from  trying to trace where the FSKD (think its called 
DIGI1) goes to - was hoping  maybe a little SMD xsistor but looks like its into 
an IC .

Any idees of what to look for next ?? I can replace a little 3 or 4 termninal 
SMD device but not an IC - hope its not a trip to the Mother Ship. 

Guess maybe I wil try AFSK today .

Re: [Elecraft] [K3] RTTY baud rate reverts to 75

[Mike K2MK]

Hi Randy,

Same problem here. I thought I had figured out how to keep it at 45 baud but
I was mistaken. It always reverts back to 75. I'm using AFSK so it isn't
really a problem but I have the P3 with SVGA option and I normally have the
data display turned on. I'd rather see a correct decode instead of gibberish
on the external monitor used with the P3.

Re: [Elecraft] K3 - RTTY FSK-D power

[iw1ayd - Salvatore Irato]

Hi Hank and all.
It's almost the same as I see it here on the KPA500 PWR diplay. Diddling 
RTTY FSK signal make the K3 Pout bubbling a bit. When at a steady 80W 
Pout without of FSK without diddle I add the diddle the KPA500 move very 
fast around 80W. I couldn't appreciate the real numbers as they move too 
fast and the KPA500 is also fast changing. The same at 40W at at the 
100W Pout level. The same effect is well seen also on some PS 
instruments. When the K3 is diddling in RTTY the current shows some 
diddling also.


That's almost empirically, but it is.

The same effect was seen on the last FW release and also on the one before.

Re: [Elecraft] K3 - RTTY FSK-D power

[Joe Subich, W4TV]

The K3 power calibration is done at CW (key down) but FSK includes a
bit of shaping to reduce key clicks.  That adds just a bit of peak
to average power difference and would account for a small difference 
between CW and FSK.  I measure just under 1 watt difference at 80 W 
between CW and FSK conditions - about 0.6 dB.

[Elecraft] K3 - RTTY FSK-D power

[Pfizenmayer]

If I set power to 100 watts  on CW the K3 setting  and my Array Solutions 
Powermaster power meter read the same within a watt or two. Leaving the K3 
power set at 100 watts on CW and switch  to DATA and run MMTTY diddles  , the 
Powermaster is reading 116 watts. Sending RTTY text it bounces between 115 and 
105 watts or so. 

K3 SN 7536 latest non beta firmware.

Powermaster  or something in K3 ??? This is not Powermaster II and I have two 
couplers , both do the same.  SN2441 box.

Re: [Elecraft] K3 - RTTY FSK-D power

[Don Wilhelm]

Hank,

My initial guess is that it is your Powermaster.
I have recently built a 4 State QRP QRPometer to use when testing QRP 
transmitters.  It is an accurate meter as long as the waveform is a good 
sine wave (Good CW signal), but I have also discovered that it does not 
read correctly if the waveform is other than a clean CW signal (like 
PSK31 or RTTY).  The cause is the detection methods used in the meter.


I cannot say that your Powermaster is doing the same thing, but I will 
venture a guess that it is related.


The K3 does a very good job of controlling power at the requested level, 
no matter what the mode.
But then your question is valid - I don't know your particular answer, 
and I do not have a Powermaster meter to test with.  I am only offering 
my suspicion.

Re: [Elecraft] K3 RTTY

[Mike Reublin]

Thanks to some excellent suggestions, I was able to get receive working, but 
transmit is still a no-go.

I cannot get an ALC indication. I've run the sound card volume up and down it's 
range. I can hear the tones thru the K3 speaker, so they're getting in.

It's got to be something so simple I'll feel compelled to double dope-slap 
myself.

Re: [Elecraft] K3 RTTY

[Don Wilhelm]

Mike,

Was that a plain USB soundcard, or is it a digital interface box (like 
SignaLink, RigBlaster, etc.)?
If it is a digital interface box, most of those are set for microphone 
level output, so dig into the documentation and find out how to set it 
for Line Level output.  Line level is 50 to 100 times the amplitude of 
mic level.

Re: [Elecraft] K3 RTTY

[Mike K2MK]

Hi Mike,

If you hear the tones in the K3 speaker then I assume you mean that you are
hearing them through the monitor. This tells me that the tones are getting
through to the K3 and that you are in transmit (red light). If you are in
DATA Mode AFSK A you should be able to adjust the MIC knob on the front of
the K3 for proper ALC indication. You should then be able to crank up RF
output with the PWR knob (unless you are in TEST mode).

Mike K2MK

ok here are a few things to follow for rtty/digital with the kx3

1) buy the cable kit from Elecraft

2) use a app like fldigi and use hamlib under rig control to do the keying

3) follow this link http://k4mtx.wordpress.com/2013/04/11/kx3-fldigi-setup/

there is no need for a signal link or other digital interface card .

Re: [Elecraft] K3 RTTY

[Wes Stewart]

In MMTTY make sure that the correct sound card is selected for both TX and RX.  
Only a problem of course, if you have more than one card.  (Don't ask me how I 
know this:-)

Also make sure that the Mark and Shift that you select in MMTTY match the Mark 
and Shift (pitch) in the K3.

Is the K3 actually going into transmit (red light on)?
