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.

Psker

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

Doesn’t work anymore

Looks like this app hasn’t been updated in awhile and that’s a real shame. It WAS the best PSK app for iPhone/iPad. Now, it just flat out doesn’t work on recent versions of iOS. I’ve had the app for years, but haven’t used it in awhile. Much to my disappointment, I opened it up today and it just doesn’t work. Just compared to the other PSK app, it appears this one needs to be updated to allow it to ask for permission to use the microphone (for audio input). This app doesn’t have a setting for it, the competing app (which frankly isn’t as good - but it works), does have that setting. Let’s hope the developer updates this app and I’ll be happy to give it a high rating. 73, KI4ASK
