So far so good!

So far, this app is doing what I need it to do: get me on the air with PSK31. I use a small speaker next to my iPad to receive the signals, and use a hand mic and VOX for transmitting. Only issue I have isn’t really with the app itself: I also log on my iPad, so I can’t have my log open AND use the app. I guess I need to hand log during PSK31 and then transfer into my logging program later.

Not worth the buy

The app is promising a lot. But in reality it does not clearly decode, the waterfall is almost complete black, even ongoing qso‘s are almost not appearing. There is no good squelch and so the app keeps decoding thousands...

Nice try, but not working.

Works wonderfully. I made myself a small tnc with two transistors that uses the mic dc bias as power supply. Note that the audio comes out on one channel only.

Wasted $2.99

This app does not work since it does not show up on privacy or in the app list you will not be able to have it listen to any radio signal. Total waste of money.

Doesn’t receive

This app doesn’t work. Will send PSK but doesn’t receive. Waste of $3
