Digirig with Winlink and UZ7HO soundmodem

The radio keys up when using the PTT A and B test in the software. I also have it PTT ing now, but it won’t release until I hit cancel on the session window.
I’m also getting a ‘unable to open com xx when initiating a session until I unplug the USB cable and plug it back in.

Thanks

Sounds like a case of RFI. Please check “sticky PTT” section in the troubleshooting guide.

I did take that into consideration.

I’ll try again.

Thank you

You can confirm this by trying the same with the minimum TX power and into the dummy load.

I’ve given up for now.

I have done everything I can think of to make this work. I’ve changed every setting in the soundmodem, tried several different baud rates, gon back to default settings, added ferrite beads to all cables, changed output power to 1 watt, used a dummy load, changed settings in Winlink, and no joy.

Back to the Mobilinkd for now.

Here is an “Almost Everything in One Place” checklist for setting up Digirig with Winlink, Soundmodem and a Baofeng UV5r-style HT. This setup works for me.

Thanks, I’ll take a look.

I just had the same problem, and I solved it by selecting TCP in the Serial Port drop down box in the Winlink Express Packet Settings window. Apparently I had selected COM10 as that is what my Digirig is set to, but of course UZ7HO could not open the com port because Winlink Express had it opened already.

I followed these great instructions, but the UV5 isn’t transmitting. I tried adjusting the volume on the radio without success. I assume one of the sound card settings needs to be adjusted. Which setting should I adjust to get the radio to transmit?
Thanks,

I don’t know. I gave up using the Digirig with UZ7HO. I couldn’t get it to work.

Radio not transmitting and audio settings are separate concerns.
Please post the screenshots of your settings and we can go over that.

The first time I tried Digirig with my Baofeng HT, I had trouble because I was not pushing the Kenwood connector firmly into the HT. It took more force than I expected to seat it properly.

“Failure to Start: Sound Modem” is the message that I receive with Winlink and Digirig (145.010). On the other hand, APRS and Digirig work together (146.52). Why?

That’s frustrating. Do you have the path to soundmodem set in Packet Winlink Session → Settings:

Only change: I had 500 and you have 300 – so I changed that. Perhaps I am not selecting the correct iGate.

@Carol_Flaherty based on the error message, winlink packet session manager is not able to find or not able to execute the soundmodem application. Is the path to soundmodem correct?

On the other hand, APRS is still working, right? In North America the APRS frequency is 144.390 MHz.

I use 144.390 for APRS (successfully) and 145.010 for Winlink (unsuccessfully).

Thanks for posting those screenshots. From the error message, it looks like C:\Users\Demo\Desktop\soundmodem.exe is not the path to the soundmodem application. You can take a look at the path setting in the APRS application, or use the search feature in the file manager or perhaps the Start program to find where soundmodem.exe is located in the file system.

Does that make sense? You are very close to success!

Ah, hah! I’ll bet that is not the path! Let me work on that!
