TH-D74


 

Hi all,

Any ideas on how to get the Kenwood TH-D74 sending and receiving email messages with Pat? It has a KISS TNC built-in...

I played around with this exact thing on Friday. I was able to get my radio connected to the Pi via Bluetooth, and I got it to send enough data to connect to the RMS Gateway. Once connected though, it would get hung up and sit there indefinitely.?

I followed this guide ?starting with the section axports file. You may choose to follow the full guide, but this is what I did to get the radio paired to the Raspberry Pi. I installed Blueman and connected via the icon from the menu bar rather than the command line. To install, run the following commands:

sudo apt-get install bluetooth bluez blueman
sudo reboot
After that installed and rebooted, there was a new Bluetooth icon on the menu bar. I connected the radio to the serial port, which I believe pops up as rfcomm0 once connected.

From there, just follow the guide. From the Pat interface, you'll want to connect using AX25. Like I said though, I wasn't able to get any further than Pat confirming it had connected to the RMS Gateway. I don't know if it was something on my end or the other end. I'll have to play around with it some more. And you'll have to let us know if you have any success as well!

Could this also be used for the Pi-APRS app?

Not without modifying the Pi-APRS source code. Pi-APRS uses direwolf as the TNC. Since the radio has a hardware TNC, you wouldn't be able to use it along with direwolf.

Thank you sir. That's what I needed to know.

Mitch:

Thanks for the information. I had read that blog post over the weekend, but although the autor provides crucial information, I was unable to tie his ideas together enough to make the project work.

On the other hand, today I put some time into this and after consulting several sources, including a couple of videos from Mr. Oleham (KM4ACK), I successfully put the pieces together (i.e. connected a Pi 3B+ via Bluetooth to a TH-D74 and reliably and consistently sent and received emails through Pat). Tomorrow I will go through the process again from the ground-up. If I can validate the procedure, I'll come back to this forum and share the steps (if it is OK with all).

Hi, Jason. Best regards.
