User Reviews and Ratings
★★★★☆SDR is NOT shortwave streaming
SDR is Software Defined Radio and needs an external receiver ("radio") plugged into your audio/microphone jack of your iPhone. The app is the controlling software for the external radio. There are also Windows and OS X applications that will let you do the same thing. The sample files in this app are just to give a taste of how the app works. This app does not stream shortwave radio nor is it supposed to.
Please read the description of this app and google SDR or Software Defined Radio before do
★★★★★Great SDR file analyzer
If you don't understand what this is, don't download it and then make useless remarks in a review. It's not a receiver, not by itself anyway. While you could use it real time by routing the iq stream from an external receiver to the mic input I "feed it" prerecorded IQ files I generate from a digital receiver connected to a PC. This software provides portable, offline analysis and demodulation of signals within the recorded spectrum of the file. Pretty amazing feat give the limited horsepower
★★★★★Works.
Tried application with IQ samples dumped from others receivers and works great. however I am wondering and requesting support for the USB RTL-SDR dongles. Preferable via a direct usb connection through the camera connection kit. Or via RTL_TCP (samples over the Internet live)/ IQ sample dumps. It would be awesome, because then I could avoid buying a nexus for mobile SDR usage.
★★★★☆Panadapter for KX3
I bought this app to use as a Panadapter with my Elecraft KX3. For only 99 cents it's a real bargain. I connect the iPad to my radio through a Griffin iMic and the Apple camera connection kit. I use the tuning knob on the radio and watch the peaks on the spectrum display move left or right, depending on which direction I'm tuning. When a peak is at the center of the display, I hear that station coming out of my radio. The waterfall display is a lot harder to use this way, so I only use the sp
★★★★☆ISDR
For 99 cents it's hard to complain about this app.
Struggled with a few poor connections but once the iMic was properly connected to the KX3 everything worked as advertised.
Panadapter bandwidth is limited to a max of 44 kHz as near as I can tell, but the resolution on the iPad was great, and it was easy to locate strong signals and relatively open spots in the cw bands to facilitate working expeditions.
No point and click to tune the radio obviously, but a great addition to the KX3 if you're
