Recently I was looking for alternatives to allow me to send Winlink messages

over the 2m band via packet. One of the problems that I can’t seem to solve on

Linux is making AX.25 and Direwolf work properly. I’ve read through (and

followed) a dozen tutorials, but no matter how hard I try, I just can’t seem to

make that work.

One alternative is using Windows and the RMS express program coupled with

Soundmodem. However, as you all know, I am not too fond of Windows, and I

principally use Linux and other open source operating systems. It also is not

very handy to have to dual boot my laptop into Windows which means suspending

the usual JS8 and other HF operations to do Winlink. So I needed another

option.

Of course, there is Wine or virtual box as well, allowing me to run Windows, or

windows programs within Linux. But, for one thing, it really just goes back to

using Windows in a different format. Also, for some reason, having multiple

signalink USB devices seems to be giving me a lot of trouble. On one boot, the

HF signalink will be device 2, and the vhf one will be device 3, but on the

next boot, it gets reversed.

Doing a little digging, I came across WoAD, Winlink on Android. At first glance

I thought it just allowed you to do telnet winlink connections, but after

playing with the program, I found you could actually use it to do ardop and

packet as well! I thought there was no way it could detect and use the

signalink, but after connecting it to the OTG cable, it fired right up.

I will mention, that at first it didn’t transmit out, because the default

setting was for the output to be on the right channel, and I had to change the

settings to the left channel to get the output to work. However, other than

that, it worked right out of the box!

I plan to play with it a bit more, but so far, I’m pretty impressed with the

app! I can see this being very useful with a handheld or vehicle mounted radio,

too, which makes for a very small package to carry in emcomm situations.

Linux – keep it simple.
