I was waiting for AOS on 145.825MHz to receive APRS from the ISS.
Then I heard the familiar AX25 packet signal twice.
I was happy that I was finally able to receive the ISS signal, but even after the ISS was lost, I could still hear it.
It was actually a signal from ground station AX25.
I thought I would need a TNC for the AX25, but when I searched on Yahoo Auctions, it wasn't listed.
I used to have a lot of TNCs when I was using them for transfer BBSs and Terakoyas, but now I don't have any.
But when you hear a signal, it's the nature of amateur radio operators to want to see it.
So I looked into it.direwolf.It turns out that this software can replace TNC.
In fact, it seems that software is now the mainstream, not TNC.
Test environment.
Transmitter: FTDX3000, Audio USB connection, PTT: VOX 51.50MHz dummy load
Receiver: FT-891 Audio SCU-17 USB connection
To start it, change the directory at the command prompt.
C:\direwolf>direwolf -c direwolf.conf

However, direwolf does not have CAT control.

The nostalgic sound of the AX25.
The problem is that Direwolf does not support CAT control.
To control PTT, you need to create an interface with RS232C DTR and RTS.
Or you may need to rebuild it with Hamlib support.
Official Windows "finished binaries" that include Hamlib support are generally not distributed.
Therefore, if you want to use PTT via CAT (hamlib/rigctld) on Windows, you need to build it yourself with Hamlib included, or
A more realistic option is to use Dire Wolf (with Hamlib) for Linux/Raspberry Pi. FlexRadio Community +1.
If you really want to just download and use
For Linux/Raspberry Pi, Hamlib is generally included in distribution packages and builds.
At startup it will say Includes optional support for: hamlib. groups.google.com
There is no official "complete Dire Wolf with Hamlib" for Windows.
Therefore, building it yourself is the norm (there is also an explanation that summarizes the steps). Streaming Matters
Build your own or alternatives
Building with Hamlib on Windows (Cygwin/MSYS2 etc.)
Example procedure: Install Hamlib first → Build Dire Wolf with cmake → When you start it, "hamlib" will be displayed. Streaming Matters
After that, start rigctld and write PTT RIG 2 localhost:4532 in direwolf.conf to use CAT-PTT. GitHub
Hamlib + Dire Wolf on the Raspberry Pi (Windows is the client)
Another common scenario is when Dire Wolf on the Pi uses Hamlib for PTT, and the Windows app connects via KISS/AGW. groups.google.com.
PTT without Hamlib.
- PTT on RTS/DTR (via USB-Serial): PTT COMx RTS, etc. GitHub.
- PTT via GPIO on CM108/CM119: PTT CM108 (supports USB sound only). GitHub.
*CI-V (CT-17) is a "control line" and not a PTT pin, so if you want to use PTT with CAT,
the Hamlib/rigctld route is ultimately the safest option. Hamlib
If necessary, please provide an example of the rigctld command for the IC-820H (CI-V) and a completed example of direwolf.conf.
I will transcribe it based on the current connection (audio via accessory terminal, control via CI-V).
