[K3] RTTY Setup

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

Re: [K3] RTTY Setup

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

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).

[K3] RTTY setup

In reply to this post by W0JFR

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.

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

[K3] RTTY Setup: Solutions

In reply to this post by W0JFR

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: [K3] RTTY Setup: Solutions

John,

Have you submitted these items as a bug report to the N1MM Logger+
developer team? I bet they would appreciate hearing about your issue.
