RTTY Problems on K3

I am fairly new to the K3 but have no problems setting up N1MM and
other software, getting things to work properly. My problem is I
cannot get RTTY to send/TX. I have made a homebrew interface with
optoisolators for both the FSK line and the PTT line. I'm going from a
separate serial port, pins 3 and 7, for FSK and PTT, to the Assy(15
pin) connector. To pins 1 for FSK, 4 for PTT and 5 for ground.

When I run MMTTY I cannot get the rig to key. If I switch to SSB or CW
and use the CAT line to work the PTT, no problem. If I switch to RTTY
and try to use the CAT line it will not key the TX. I've tried a
variety of setting in MMTTY and get no TX. I have a 1000MP set up with
a similar homebrew interface and have no issues.

Can anyone shed some help on me?

Re: RTTY Problems on K3

I think you need another program to make this work. It intercepts the serial port for the FSK/PTT and makes it all work together.

I use 2-Tone instead of myth and seem to get by with just it and n1mm.

For interface I use my WINKEYER-USB with the latest firmware. I use a “Y” adapter in the KEY line. The second line goes to K3/Acc2 FSK pin. “Diddles” go to FSK and “Dit-Dahs” go to CW. works well.

Bill,

You could begin by breaking the problem in half - test at the output of
the optoisolators.

Front Half - Test what's coming from N1MM and MMTTY:
Put a scope or meter on the PTT line and click [TX] in MMTTY. Does the
line go low and stay low for the duration of TX?Put a scope or meter on
the FSK line and click [TX] in MMTTY. Does the line toggle at 15ms RTTY
intervals? With a meter the voltage would drop, indicating lower average
voltage - but something would be different between RX and TX.
>If this doesn't work, first place to check is the MMTTY >Options >Setup
>TX, "PTT and FSK" and >MISC, "Tx Port"

Back Half - Test whether the K3 is sending RTTY:
Use a clip lead to short the optoisolator PTT output to ground. Does the
K3 go to TX?While the K3 is still in TX, use a second clip lead to short
the optoisolator FSK output to ground. Does the TX monitor tone shift?

Thanks for the help on this. Found the problem. All working now. My eyes don’t work like they used to. The PTT side of my home brew switching box was not working. Re-solder and all good.

Re: RTTY Problems on K3

Over the years I have built all of my interfaces. Started with
optoisolators but when trying to go SO2V I couldn't make them work with the
outputs paralleled. Now I have 2 db9 serial plug with a single 2n2222 & 1k
resistor in each, outputs paralleled into a db15hd for the acc on the K3.
PTT is via CAT. This is the simplest solution that I have found. I use I/O
usb to serial converters with 4 or 8 ports. Enough to run everything on
rs232. Only use usb for CAT and sound. This is the least number of cables
and connections I have used, and I like how it works. Am really starting to
regret selling the house and moving into an apartment building though.
