by wodowiesel
Experimental !
based on Google Radio Receiver 1.1.5_0 (for Chrome =< 70)
Chrome Extension Scripts by Jacobo Tarrio from 30. Juni 2016
Chrome Store Radio-Receiver
Git-Link user: jtarrio under Apache License v2.0
Tested with Chrome v73.0.3683.86 official x64-bit (Browserversion >= 71)
Receive and listen to FM, AM, SSB radio broadcasts on your browser using an RTL-SDR (RTL2832U-demodulator-chip) USB digital (TV) tuner.
This application does FM, AM, SSB demodulation in the browser and can capture the radio signals as .wav
-
This version was improved with adjustable styles, window-sizes and better permission controls
-
Supports most compatible R820T & T2 tuner IC chips now (maybe some E4000 !?)
See PIDs & VIDs & Names in the Compatibility-List (43 Devices incl. Generic now)
Features:
-
Scanner-Function
-
Recorder (.wav)
-
Free-Tuning mode with Steps
-
Supported modes: W-FM, N-FM, AM, SSB
-
Shift-Correction - Up/Down-Converter needed!
get this program via:
git clone https://github.com/wodowiesel/SDRFunk
or download the ZIP-File from the Release-Site (all included)
For generating package just use the builder/packer in the extension manager of the browser.
a) Use the extention_1.1.6_0.crx (.pem for key) installer from the package
b) Unzip the extension and load it via Extension-Manager 'chrome://extensions' (in Experimental-Mode)
Path: C:\Users\YOURUSERNAME\AppData\Local\Google\Chrome\User Data\Default\Extensions\APP-ID\1.1.6_0\
('unsecure' warning because it's not directly from Google Store)
Permissions: Can be managed in the App-Details or in manifest
You can use _ locals if you want to, just remove the x in folder name (english/german).
JavaScript must be activated in your browser!
Run with admin/root permissions:
You can open the App via 'chrome://apps' and create a desktop short link via mouse right-click"
Use '. dot' as decimal-comma separator!
Radio works with .wav-file with 16-bit PCM @ 48000 [Hz] mono & stereo / 1 [kHz] - 12.000 [MHz] range.
- Tip: You could use just a copper wire for 2 m/70 cm-band or other lambda(1/4)-antennas (17.5 cm/6.9" in on PMR)
or any other antenna-configuration you like to use if you're an advanced amateur-radio-operator.
-
You can use an LNA (USB 5 V or external) for improving signal-strength
-
Bias-T (12 V vertical or 18 V horizontal on LNB as PLL-type) for satellites @ 10-12 [GHz] like Es-Hail.
-
I use the NooElec NESDR SMART with an LNA
0.5 ppm, ultra-low Phase-noice TCXO / @ 1kHz Offset: -138 dBc/Hz / @ 10kHz: -150 dBc/Hz / @ 100kHz: -152 dBc/Hz
- You can use for HF/MF/LF/VLF/ULF also an Upconverter
for Input-frequencies 100 kHz - 50 MHz to shift to Output 125.100 MHz - 175 MHz & intern TCXO works @125 MHz.
It's not specified for 10 kHz - 99.9 kHz but works ok.
-
Use only (original/tested) power supplies and cables
(I use 2x ~5 V/500 mA via USB 2.0 for the LNA & SDR & USB-Wattmeter for monitoring)
-
Antenna should be grounded if possible to avoid damage
-
You can try a 1:X Balun like 1:9 (to reduce internal resistance) if using long HF antenna for Short Wave
-
Dummy-load: 0.1-100 W @ 50 Ohm "cement" or similar with cooling-ribs with fan for testing
-
Private Project! Work in Progress (WIP)
-
I'm not a professional so NO guarantees or warranty for any damage or similar!!
-
Usage at your own risk !!
-
Check laws of your country first! Some Frequencies are prohibited/illegal or need a HAM-Licenses!
-
Listening / Spying & Decoding on encrypted frequencies/channels without permission is illegal!
- Help / Testers / Push-Pull-Requests / Issue- & Bug-Reports and Feedback always appreciated!
You can use it for your projects too, if you want to!
Thank you and have fun! 73 :)
