UHSDR stands for UniversalHamSoftware Defined Radio. The project provides the firmware to run standalone HAM transceivers. It currently supports STM32F4 and STM32F7 MCU based QSD designs. The current firmware provides receive and transmit for various analog modes (SSB,AM, FM) including modes like Synchronous AM, plus digital modes like FreeDV and of course CW (including Iambic/Ultimatic keyer). An USB CAT and audio interface is part of the firmware as well. The bootloader, which is another part of the project, permits to update the firmware and bootloader using various means like USB disk or USB cable.

The base of the firmware was started by Chris, M0NKA, and Clint, KA7OEI as part of the mcHF project. Thanks to the Open Source Approach (now with the GPLv3 license) the mcHF firmware has been extended in this project with new functionality and also with support for use on different transceiver hardware.

The intent of this project is to give full support for mcHF (and all other known and listed hardware platforms) as long as there are contributors willing to support the given hardware.

So this is the best place to start with up-2-date developed firmware and bootloader for mcHF.

If you only want binaries, you can find them for stable releases and pre-releases in "github releases".

Up-to-date binaries of actual development are available as "daily snapshots". Explicit Versioning is only done in RELEASES. For identifying daily snapshots you must use build time stamp which is shown in splash screen and the System Info menu.

If you want to see the recent progress of the project, have a look at the commits here.

All this is bundled in startup page.

Have fun - Open-Source opens possibilities!
