I’m new to amateur radio. Just got my license in February when I passed my Tech and General tests. So a lot of this stuff is still new to me and I still find it a bit amazing, like this set-up. This is an ordinary iPad running a program called PSKer, available on the App Store. Using no additional hardware at all, just the iPad, with it’s internal microphone and speakers, it will decode and send text in PSK31. Now I’ve been working with computers, radios and electronics for ages, but sometimes modern technology still surprises me. I haven’t tried transmitting with it yet. That’s a bit awkward, but decoding works pretty well, although you do need a very clear signal with little or no interference, which is sometimes hard to do.
And look at that nifty waterfall display! Heck, it was worth the $3 just for that!
