Read the ManualHamMixer is a complete ham radio station control suite developed by CT7BAC. It includes a Windows desktop client with a dual-source audio mixer, full radio control via CAT, DSP processing, waterfall display, and CW keyer. Combined with the HamMixer Server and Mobile App, it enables secure remote operation of your station from anywhere in the world.
HamMixer currently supports all Icom transceivers using the CI-V protocol, including IC-705, IC-7100, IC-7300, IC-7610, IC-7760, IC-7851, IC-9700, and any other CI-V compatible model. Support for Kenwood, Elecraft, and Yaesu radios is in development, with desktop local mode already functional for these brands.
The free trial lasts 14 days and includes full functionality — no features are locked. No credit card is required. Simply download and install HamMixer to start your trial. After the trial period expires, you'll need to purchase a license to continue using the software.
After the 14-day trial expires, you must purchase a license to continue using HamMixer. The software will prompt you to enter a license key. All your settings and configurations are preserved — just activate your key and you're back in business.
The Desktop license allows activation on 2 machines. The Full Bundle license allows 1 server activation + 2 client activations (3 machines total). This covers typical setups where you have the server at home and use the desktop client from different locations.
We do not offer refunds. The 14-day free trial with full functionality serves as your evaluation period. This gives you ample time to test every feature and ensure HamMixer meets your needs before purchasing.
Yes. The mobile app connects to HamMixer Server running at your home station. The server provides the bridge between your radio and the mobile app over the internet. You'll need the Full Bundle license which includes both the Server and the mobile app (the mobile app itself is free).
Yes, for local operation. Connect your radio directly to your PC via serial/USB and use HamMixer Desktop without any internet connection. Internet is only needed for remote operation, WebSDR audio mixing, and periodic license validation (with a 45-day grace period if offline).
Absolutely. Remote connections use TLS 1.2+ encryption for the control channel and AES-128-CTR encryption for the audio stream. The encryption key is exchanged securely over the TLS channel. Additionally, the server supports IP whitelisting and has built-in brute-force protection.
HamMixer Desktop and Server currently run on Windows 10+ only. The mobile app is available for mobile devices, with iOS support in development. Linux and macOS versions are under consideration for future releases.
Your license key is delivered automatically via email within seconds of payment. Check your inbox (and spam folder) for an email from HamMixer containing your key and activation instructions. If you don't receive it, contact us at ct7bac@gmail.com.
Yes. Deactivate the license on your old machine (Help > License > Deactivate), then activate it on the new one. The system also automatically tolerates one hardware component change (like replacing a motherboard), so minor upgrades won't require deactivation.
The WebSDR mixer combines live audio from your transceiver with audio from internet-based WebSDR or KiwiSDR receivers. HamMixer automatically synchronizes the two audio streams (compensating for internet delay) so you can hear both sources mixed together in real-time. This is particularly useful for monitoring your own signal or for dual-diversity reception.
Yes, the mobile app is free to download and use. However, it requires HamMixer Server running at your home station to function — the mobile app connects to the server for remote radio control. HamMixer Server is included in the Full Bundle license.
Pedro Silva, Portuguese ham radio operator and software developer based in Braga, Portugal. HamMixer project was born from personal needs — listen to WebSDRs in sync with the radio and the desire to operate my station remotely with professional-grade tools, low latency, and no compromises, specially from mobile phone.
What started as a personal project evolved into a comprehensive suite that I'm proud to share with the amateur radio community. Every feature has been designed and tested on real-world ham radio stations, because I use HamMixer myself every single day. Work a VK station during an Uber ride through my mobile... Pure fun!
