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

Outdated

I wish the developer would release an update with iPhone X display support. Goes to show how long it’s been since this app was updated. It’s nice to see my Xiegu G90’s waterfall on a larger screen (the radio only has a 1.8” display), but frustrating knowing it could be larger still.

Very useful!

Exactly what I was looking for. I plan to use this app with KX2, QCX, and QSX in the future. Although I currently have none of these radios, the demo file gives me a very good understanding of what this app can do. Mind blown with the sdr/dsp stuff.

iSDR 3.0

Great app, used with recordings and was amazed! Waiting on a SoftRock Lite to test it live, but I am sure it will perform great! Thanks for making SDR portable. K7SWF

Great- but

Worked great, and then it just quit working when I installed e new version. Hope it gets fixed, as there's nothing at all like it.

What a great App !!!

This is an amazing app that does everything I would expect from an expensive paid app. Certainly the center piece for a great QRP or Field Day go kit.

iSDR

This is an outstanding application. I use it extensively to practice CW copy. Support is quick and personal.

Not multi-tasking compatible

You STILL can't put the app into the background and it keep working. Major drawback.

Awesome app

I just got this app and now I can listen to any shortwave radio station whenever I want, wherever I want!

Not bad

Pretty neat little app.good audio.

Needs FT-8 mode

Any chance you would consider making an FT-8 encoding / decoding iPhone app? I think this would be very popular. 73! Jim - KH2SR Needs support for Apple Watch
