Android App RFAnalyzer Now on Google Play with Support for the RTL-SDR

Previously we posted about the new RFAnalyzer Android app for the HackRF which has a RF spectrum and waterfall display. Now RFAnalyzer is available on the Google Play store with experimental support for the RTL-SDR dongle. The app also now supports AM and FM audio demodulation.

The app is fully open source and the code and APK can be downloaded for free from its Git repository. Alternatively, the app can be downloaded from the Google Play store at a small cost of $0.99 USD.

To use the app you’ll need a USB OTG cable to connect your HackRF or RTL-SDR to your Android phone. More information on the app can be found on the authors blog.

An alternative Android app to RFAnalyzer is SDR Touch.

    I’ve been trying to buy RF Analyzer… via Paypal from my phone using GooglePlay. I enter the paypal info and always says there’s a problem. ??
    Mr. Mantz, if you would, please send request via Paypal and I’ll gladly pay you from the posted email on this comment. This looks like a great application.
    Thanks

      I’ve tried adding a second Email account to my phone. that didn’t’ work. I may try to add a second email to my Paypal Account. Anyone else having a problem buying Apps via Google Play?

    Hello and thank you for your application to me is very useful to the study of radio frequencies. Regarding the Hackrf I also found many defects aliasing, frequency image and the peak shape (inverted boat or ax) on strong signals. These very troublesome phenomena in the analysis of the spectrum are less visible with RF-analysis with respect to SDR RTlSharp. I think it is a problem of design of the CSD board and firmware. For aliasing, I observed, for example in a window analysis 140 150 mhz has 10 MHz sampling, we also have other signals of two other beaches that come to mix the real spectrum: it s ‘is the 130 to 140 MHz and 150 to 160 Mhz. The problem is the same on UHF. The only way to know if the signals are those of the scanning frequencies Results Showing is to move in frequency as unwanted signals a +/- value of frequency echantillage are strongly attenuated in the central third of the spectrum window . The aliasing is very visible especially in the tier 1/3 left and right of the window of the spectrum analyzer. I also noted that the center frequency is not very visible on the screen of my 7-inch tablet Archos TiTAN70 even with the option of the characters in general. A visible indication of the frequency of selection (to listen) or central frequency would be a real plus for me. It would also be really great to integrate the Hacktransfer (= HackTest) has RF-Explorer .Thanks again for your work. It’s fabulous tool for Hamradio. Cordially Pascal F1MIJ

    you can get it from github for free or buy it from google store to donate the project…
    isn’t it better to make donation directly to the author instead to donate google and the author receive only a part of it?

      I agree, Google grabs 30% of all sells -.- But it was definitely the easiest way to enable supportive donations.

      I might just provide a BitCoin wallet address on my blog though…
