In a world flooded with streaming apps and online radios, sometimes you just want the real thing — good old FM radio that doesn’t drain your data or rely on Wi-Fi. That’s where RFM Radio comes in! This awesome app taps directly into your phone’s hardware FM chip , letting you listen to local stations anytime, anywhere — even without an internet connection.

What is RFM Radio?

Developed by Vladislav Veluga, RFM Radio is an open-source (GPL-3.0 licensed) app designed for Android phones with Qualcomm Snapdragon processors. It’s not your typical internet streaming app — it actually uses your phone’s built-in FM tuner to pick up real radio waves. That means crystal-clear local radio right on your device, no buffering, no data fees!

Key Features That Rock:

• Real FM Tuning: Uses your phone’s Qualcomm Snapdragon FM chip to listen to real broadcast radio.
• RDS Support: Displays station info like Program Service (PS) names and Radio Text (RT) so you always know what’s playing.
• Signal Strength Meter: Shows signal strength in decibels (dB) — find the best spots for clear reception.
• Record Your Shows: Save your favorite broadcasts as .wav or .mp3 files to replay later.
• Favorites Lists: Organize your top stations into multiple lists for easy access.
• Auto Station Search: Scan the airwaves to discover all available stations nearby.
• Root Access Required: To work its magic, the app needs root access on your phone.

Which Phones Work?

Only smartphones with Qualcomm Snapdragon processors are supported — but not all models. Snapdragon 632 and 820+ are excluded due to hardware driver issues. Check the official repo for the latest supported devices!

Why Use RFM Radio?

• No Internet Required: Perfect for travel, remote areas, or if you just want to save data.

HamClock is a powerful tool designed for amateur radio operators, providing real-time propagation data, satellite tracking, and more. This guide will walk you through installing HamClock on various UNIX-like systems, including Raspberry Pi, macOS, Debian, Ubuntu, FreeBSD, and others. Whether you’re using HamClock for monitoring solar conditions, DX cluster spots, or tracking satellites, this step-by-step tutorial will help you get started.

Step 1: Install Required Dependencies

Before installing HamClock, ensure your system has the necessary dependencies installed. These dependencies vary by operating system:

For Raspberry Pi and Debian-based Systems:

sudo apt-get update
sudo apt-get -y install curl make g++ libx11-dev libgpiod-dev xdg-utils

For Ubuntu:

sudo apt install curl make g++ xorg-dev xdg-utils

For macOS:

First, install XQuartz and Xcode. Then, open “More developer tools” and install the command line tools. On macOS Sequoia, you may need to run:

xcode-select --install

For FreeBSD:

sudo pkg install gcc xorg gmake curl

Then, use gmake instead of make.

For NetBSD:

First, install pkgin, then run:

sudo pkgin install gmake curl

Use gmake instead of make.

For RedHat or Fedora:

sudo yum install gcc-c++ libX11-devel xdg-utils

For Alpine Linux:

setup-desktop
apk add g++ libx11-dev curl linux-headers

Step 2: Install HamClock

Once the dependencies are installed, proceed with downloading and installing HamClock. There are two methods depending on your operating system.

For Raspberry Pi (Automated Install):

cd
curl -O https://www.clearskyinstitute.com/ham/HamClock/install-hc-rpi
chmod u+x install-hc-rpi
./install-hc-rpi

Follow the prompts and answer y or n as needed. This script will automate the installation for you.

For Other UNIX-like Systems (Manual Install):

cd
rm -fr ESPHamClock
curl -O https://www.clearskyinstitute.com/ham/HamClock/ESPHamClock.zip
unzip ESPHamClock.zip
cd ESPHamClock
make -j 4 hamclock-800x480
sudo make install

This will install HamClock with a resolution of 800×480 pixels. If you need a different resolution, refer to Step 4.

Step 3: Run HamClock

After installation, you can start HamClock with the following command:

hamclock &

If everything is installed correctly, HamClock should open in a window displaying solar data, propagation info, and maps.

If you did not install a desktop icon, you can always launch HamClock from the terminal using the command above.

Step 4: Customize HamClock

HamClock supports different screen sizes. If you want to change the resolution, use the following commands:

cd ~/ESPHamClock
make clean
make -j 4 hamclock-2400x1440
sudo make install

Replace 2400x1440 with the desired resolution:

• hamclock-1600x960
• hamclock-2400x1440
• hamclock-3200x1920

If you want HamClock to fill the screen completely, navigate to Page 5 in the Setup menu and enable the full-screen option.

Step 5: Auto-start HamClock on Boot

To ensure HamClock starts automatically on system boot, you can create an autostart entry.

For XDG-compliant systems:

cd ~/ESPHamClock
mkdir -p ~/.config/autostart
cp hamclock.desktop ~/.config/autostart

For macOS (Create a Clickable App):

If you’re using macOS, you can create a clickable app on your Desktop:

cd ~/ESPHamClock
HCDIR=~/Desktop/HamClock.app
mkdir -p $HCDIR
echo '#!/bin/bash' > $HCDIR/HamClock
echo '/usr/local/bin/hamclock &' >> $HCDIR/HamClock
chmod u+x $HCDIR/HamClock

To assign a proper icon, follow these steps:

1. Open hamclock.png with Preview.
2. Click on the image.
3. Press ⌘-A to select the image, then ⌘-C to copy.
4. Right-click the new HamClock.app Desktop item and select Get Info.
5. Click the existing default icon in the top left corner.
6. Press ⌘-V to paste the new icon.

Conclusion

By following these steps, you’ll have HamClock running seamlessly for amateur radio use, helping you track propagation, monitor DX cluster spots, and track satellites. Whether you’re using a Raspberry Pi, macOS, or a UNIX-like system, HamClock is a great addition to any ham radio station. For more info, visit https://www.clearskyinstitute.com/ham/HamClock/
