New Digital Application - EXChat

There is a new FREE digital application out and hams will find it to be useful and fun. It’s called EXChat and uses DominoEX and the digital method of transmission.

What makes this different from other digital mode applications is that it mimics how many of us use texting and chat programs over the Internet and on our cell phones. So this application will be particularly interesting to kids as we try to attract new blood into amateur radio.

If you want to get to it and give it a try now, go to:

There is no install, just unzip the files into a directory (C:\EXChat for example) on your C: drive and start it up. All you then need to do is enter your call, select the sound card for outgoing and incoming audio and the comm port to use for PTT. Takes a few minutes to set up. You can very the baud rate to match conditions, but the application defaults to 11baud.

Rod, WI0T, and I have been using it to chat away on 40 meters each using 25 watts and vertical antennas. Rod is in St. Louis area and I am in the Cincinnati area. We have used 22 baud with great success which equals about 140 words per minute.

How EXChat differs is that it creates a chat environment by sending sentences and acts just like a chat or texting program. You type out a sentence, hit return and away the message goes. You can chat with a group on just one-to-one.

Give it a try with a friend or group of friends. I think you like it.


Airlink Express - A Hidden Gem for Digital Modes

The other day I was having a QSO with a guy who said he was using Airlink Express for his digital mode work.

Airlink Express? Never heard of it, but I love trying out new software. So I did a search and found the site for the software. How did this little gem remain so elusive for so long?

The software can be found at and is freeware, but contributions are solicited and appreciated.

The software is very easy to set-up and use. It supports PSK, MFSK and RTTY. It also has a built-in logbook and has some basic radio interface to grab frequency. Like most digital mode applications, you can create all sorts of macros to make it more efficient to use.

Airlink Express seems to be a very capable program and so far I have used it to make several contacts on PSK. I have to still try using it with the other modes but I am it will work equally well.

Give Airlink Express a try as I think many of you will like it.
