Whats new in rtl_tcp SDR v1.5.2

6 things about rtl_tcp SDR

1. Thus, the use of this app requires network access to a server, such as a Raspberry Pi (or Mac), with an RTL-SDR unit plugged into its USB port, and running the rtl_tcp protocol at an TCP/IP network address accessible from your iOS device.
2. Please do not download this app unless you are already familiar with Software Defined Radio, have an RTL-SDR or equivalent USB SDR peripheral, and have already installed and tested rtl_tcp on your Raspberry Pi, Mac, or other server.
3. The rtl_tcp SDR app can also connect to hfp_tcp for the Airspy HF+, rsp_tcp for SDRPlay devices, and lmm_tcp for the LimeSDR Mini; see GitHub for server source code.
4. Connect, via the rtl_tcp network protocol, to networked RTL-SDR USB peripherals.
5. Note that this app requires a very high bandwidth network connection in order to receive streams of real-time RF samples from an RTL-SDR.
6. No support is provided for installing any of the rtl_tcp or other tcp software needed to use this app (with a Raspberry Pi, or otherwise).

Does not work

I understand how to set up and operate these programs. Though, this one fails. Back to my android app.

Save your money and dont buy

Bought the app and never can get it to work with my SDR server. Contacted dev for support. Tried another server software he recommended. Still wouldnt work. Tried connecting to several other online SDR servers, and none will connect with the app. Google wont refund purchase. Save yourself the pain and dont buy.

Does not work for IOS

This app does not work on IOS without a secondary device (computer) plugged into it. Not boldly stated and doesn’t look like a refund will be issued.

Great

I combined $25 sdr, Ham It Up, Youloop antenna with a raspberry pi and how I have a internet accessible shortwave radio.

As a last resort, it works.

I was very apprehensive about buying this, based off the screenshots and the fact that it’s one of the only rtlsdr apps available. $10 is way too much for this. Maybe $2 would be ok but this is sub par. Sometimes it doesn’t connect, or will just decide to drop off and stop all audio and demodulation randomly. The waterfall is glitchy and doesn’t scroll. The interface is very bad. You can’t change modes without stopping the connection and changing it, then starting again, hoping that it will reconnect. You also cannot change the bandwidth of the current frequency. The ui is also glitched on the Android 8, the orange text that shows the status is down in the corner and only shows the first letter. As an only option I guess it works, but it really needs big improvements to be worth the $10.
