Magic?

Cannot believe how well this app works!
No cell coverage.
8-10 skimmers pick up my FT8 signal.
By the time I’ve tuned back to my POTA frequency and called CQ, I’m already spotted!
Recommend without reservation!

No USB access

I’m rather disappointed this app does not access usb audio for sending messages. iFTx does it well.

I was looking forward to plugging the usb cable into my pone and QMX as I do with said app above. I hope you will remedy this shortcoming in the near future.

This blow my mind

I cannot believe that someone sat down and completely solved one of the most frustrating problems for sota and pota such a comprehensive way. It's absolutely brilliant. Like someone else mentioned, the set up is a little convoluted. But if you're capable of doing pota and sota, you should be capable of doing this.

I'm continually amazed at how some people in amateur radio are doing such cool things. This is the coolest hobby. Because stuff like this exists and people just did it on their own and they make it available for others to benefit.

All-in-one field spotting solution for SOTA and POTA

Awesome app for offline (and online) spotting and sending canned messages.

Once configured it’s easy to use and works amazingly well. It seems like magic - playing FT8 sounds on the phone’s speaker near the radio’s mic manages to get the message out with just a couple of watts.

The internet and SMS spotting features make this an all-in-one solution for times when you have cellular or satellite coverage.

Astounding Perfection

This app is everything that ham radio software should be. If you’re not using SOTAMĀT for SOTA & POTA, you’re wrong. AB6D has leveraged FT8 skimmers, Garmin satcom, an elegant web server, and a concise and clean client. Between this and APRS, why activate any other way? Bravo. Please keep this going.
