Want to monitor PSK31 transmissions, without using a bulky computer? PSK31 lets you view ham radio PSK31 transmissions on your iPad. Just set your iPad next to your radio, tune in a PSK31 frequency, and watch the decoded text.

There's a waterfall display of the audio spectrum, showing all of the PSK31 transmission. Tap on a signal, and PSK31 tunes into that transmission.

Get your copy of PSK31 right now, and start decoding and displaying PSK31 transmissions in minutes.

It works, but....

It does work with my Easy Digi by KF5INZ interface. Main problem I have is that you can not change the rotation of the app. I use it with an iPad Pro connected to a keyboard case. The will not display in landscape orientation (sideways), only in portrait mode.

This makes the waterfall display small and I have to use the iPad outside of keyboard case.

If it would display in landscape orientation with a larger waterfall, then I would use it more.

Eh.....well if nothing else

Okay. So I tried this with PSK31 and it works 'okay' but not the greatest. It will not copy PSK63.

It would be great to have something like fldigi for iOS.

Needs major update

Please add support for Apple Watch.

Doesn't do a good job decoding.

Needs ability to transmit as well.
