I'm new at RTTY myself, but I have it working with MMTTY, N1MM+, and the 
K3s built-in sound card.


With MMTTY, all I need to do is hold the VOX button to turn on VOX. I 
set MMTTY's oundcard output level to maximum, the K3s MIC to 2, and the 
VOX GAIN to 10. When I click the TX button in MMTTY, my K3s keys and 
sends RTTY (hold TEST to put the K3 in test mode with no RF output).


For N1MM+, all I need to do is hold the VOX button to switch back to 
PTT, and I'm good to go. No DTR-RTS is needed.


Do not try to run stand-along MMTTY with N1MM+. Exit MMTTY. N1MM+ 
launches the MMTTY engine when you open a digital window. You _must_ 
read the N1MM+ docs to figure out how to set up N1MM+ with MMTTY.


I have attached a screen shot showing the deeply hidden check box to use 
PTT with N1MM+. If the attachment doesn't come through, email me 
off-list, and I'll send it to you directly.


Bottom line for me is: Select DATA -> AFSK-A, turn on VOX, launch MMTTY, 
and I'm on the air with RTTY. For contests, launch N1MM+, turn off VOX, 
and I'm on the air with RTTY. No sweat.


But I did have to read the N1MM+ docs to set it up to use the MMTTY engine.

Re: [Elecraft] AFSK-A with K3s

[Gary Smith]

Yes, my problem was not when sending RTTY 
with a paddle, it was when using MMTTY and 
I was trying to send FSK. All I could hear 
was one tone, not the two tones of mark 
space. I thought it was nice not to hear 
the two tones when listening. I did not 
realize I could not properly key the K3s 
without an additional hardware. 

Now I have the K3s set to use AFSK A so 
that I don't need to have additional 
hardware/connections and no longer use the 
paddles to send, only MMTTY. 

When I use MMTTY I have to have  the 
PTT-KEY set to OFF-OFF. When I switch to 
N1MM I have to have it set to DTR-RTS. I 
have problems of locked down transmission 
if I don't and switch to CW from the RTTY 
setting. As a result, I can't have both 
MMTTY and N1MM running at the same time.

I'm guessing this may have to do with a 
RTS setting in the software but haven't 
had time to work it out.

Gary

Re: [Elecraft] AFSK-A with K3s

[Triconet_2]

You and at least two dozen guys I logged doing something similar  And I would 
venture to guess that most of them were running K3s. 

I emailed one of these guys and got back the confession that 1) yes he was 
using a K3 and 2) he was sending radioteletype with the paddle. 

The inadvertent writing of A to B while attempting to engage Split accounts for 
the QRM on the DX freq, the 15 WPM RTTY with the long unmodulated tail results 
from the other. (This assumes that the operator actually knows that he is 
supposed to be operating split... too many don't)

Re: [Elecraft] AFSK-A with K3s

[Gary Smith]

Mike,

This was a very timely thread for me in 
that I have been trying to get MMTTY 
working with the K3s and missed any 
contacts with the FT4 on RTTY and only 
made a RTTY Q with the VK0 because I used 
the memories in the K3s to send RTTY via 
FSK, not MMTTY. In fact, what I was 
transmitting was just a key down and not 
the RTTY I thought I was putting out and I 
was inadvertently QRMing every time I 
transmitted.

I asked on the MMTTY yahoo group about how 
to sync the K3s properly and a very 
helpful ham from VK finally helped me 
figure out what I was doing wrong.

The info in this thread is also very 
helpful. I did find that for some reason 
when I would select AFSK A, it was still 
set at FSK D and I must not have properly 
saved the AFSK setting. Now I have it 
correctly set and its working beautifully.

I am so satisfied with the K3s, it is just 
a magnificent piece of electronics and 
makes my day better.

73,

Gary

Re: [Elecraft] AFSK-A with K3s

[Mike Dodd]

OK, I think I have it straight now. Thanks to all, and especially to 
Gene, N9TF who emailed me off-list.


For the benefit of all, here is what I learned today:

I _do_ need to turn on VOX if I want to use a logging program that grabs 
the USB control port (COM5 in my case). I had MMTTY set up to key the 
rig on COM5, but it occurred to me that I didn't have my logging 
software open at that time. So PTT via COM5 is out, VOX is in.


I don't normally use VOX, so my MENU: VOX gain was set to 0. Once I 
turned it up to 8 or higher, the MMTTY tones keyed the rig just fine.


MENU: MIC SEL is automatically set to LINE IN when data mode AFSK-A is 
selected. This automatically reverts to my normal FP mic selection when 
I switch back to a voice mode.


The mic gain must be set for 5 bars on the ALC meter. On my K3s, this is 
a MIC setting of only 2, and the fifth bar doesn't flicker as it does 
with voice, because a steady tone is being transmitted.


The MIC gain control sets the LINE IN gain. This automatically reverts 
to my normal mic gain when I switch back to a voice mode.


How convenient is that! THANK YOU, Elecraft.

Bottom line (on my K3s, at least):

* DATA MD = AFSK-A
* VOX on
* MENU: VOX GN = 8 - 10
* MENU: MIC SEL = LINE IN (automatic with AFSK-A)
* MIC gain = 2
* PITCH = Mark frequency and shift to match those set in MMTTY

MMTTY:
* Setup, Sound card = USB audio CODEC
* Setup, Misc device identifiers = RX 0, TX 1 (TX 0 is the PC's speakers)
* Setup, TX, radio command, port = NONE if using logging software that 
needs the COM port


I think that about covers it. Thanks again to all who offered suggestions.

You need some way for MMTTY to switch the K3S between receive and transmit.


Sigh Please excuse my frustration.

My original posting was clear: MMTTY _is_ putting the K3s into transmit 
and _is_ sending tones to the built-in sound card. I can hear the tones 
when the K3s is in XMIT, but no RF comes out the antenna connector.


The red TX LED on the K3s turns on, and the RF bar graph displays one 
bar, or zero watts. I can hear the tones in the K3s speaker and phones 
plugged into the rear panel.


There is no need for VOX -- MMTTY puts the K3s into XMIT if PTT is 
turned on _and/or_ if VOX is turned on.


Everything is fine except the K3s is not transmitting the audio from the 
built-in sound card.


I'll keep trying.

Make sure the TX mark frequency in MMTTY is the same as what you've chosen in 
the K3.

Last night I was receiving RTTY using MMTTY and the AFSK-A mode on the K3s.

I'm using the internal USB sound card in the K3s. I have successfully

1. Receive and decode tones from the sound card.
2. Key the K3s when I click the TX button in MMTTY.
3. Send tones to the K3s when the TX button is clicked. I can hear the tones 
in the K3s speaker and headphones. If I choose a different Mark frequency in 
MMTTY, I hear the expected tones on the K3s.


Clearly audio tones are being sent to the K3s. But no RF comes out. I have PWR 
set to 50W (into a dummy load), and when I hold TUNE, the RF bar graph shows 
that power level (half scale, 5 bars).


But when I click TX in MMTTY, and hear the tones on the K3s, the RF bar graph 
shows 0 (one bar).


What must I do to make the K3s transmit the audio it's receiving from MMTTY?

Thanks in advance.
