An amateur (HAM) radio using an RTL-SDR dongle or a remote instance of rtl_tcp.

This application is about having a bit of fun with those amazing little RTL-SDR dongles, whilst listening to HAM radio conversations. It's nice and easy to use so why not give it a try?

Bands:

144 - 148 MHz (2m)

150 - 174 MHz

420 - 450 MHz (70cm)

421 - 470 MHz

Please feel free to request other NFM bands.

There are two ways to use the application. The first is to use an RTL-SDR dongle and an SDR driver, available from Google Play. Selecting the Driver option in the application menu will open the driver page on Google Play. The second way is to connect to an instance of rtl_tcp running on a remote computer, most likely over WiFi. You will need a good network connection for this to work reliably so use of the driver is probably the preferred way to use the application in most cases.

We hope you enjoy using this application.

Using HAM FM Radio

Once HAM FM Radio is installed, you can launch the program and begin listening to radio signals. The program's main window displays a waterfall plot of the received signal strength. You can use the mouse to click on a frequency in the waterfall plot to tune the receiver to that frequency.

HAM FM Radio also includes a number of features that make it easy to listen to and transmit audio signals. These features include:

* Audio squelch: This feature can be used to reduce the amount of background noise that is heard when listening to a signal.

* Noise blanker: This feature can be used to remove unwanted noise from a signal.

* AGC: This feature can be used to automatically adjust the gain of the receiver.

* Transmit mode: This feature allows you to transmit audio signals using your RTL-SDR dongle.

Applications

HAM FM Radio can be used for a variety of applications, including:

* Listening to amateur radio broadcasts

* Listening to shortwave broadcasts

* Listening to aircraft communications

* Listening to marine communications

* Transmitting audio signals

Conclusion
