Welcome to the mchf-github wiki!

This wiki will serve as an community edited clearing house of information on the mcHF radio. Internal wiki pages are listed in the side box to the right. There are currently several good sources of information on the mcHF. The first is of course Chris's webpage. There is also a yahoo group where most of the development discussion occurs. The files section of the yahoo group contains a wealth of community supplied documentation and modifications.

Binary builds for this repository are available here .

Building the mcHF

Building your own mcHF is a lot of fun (and stress) and can be done by any motiviated ham. Yes, it is mostly SMD, but soldering SMD is no more complicated than soldering wires, tools for SMD soldering are not expensive (a good soldering iron is enough). Yes it is about 400 items and 1 of these has 100 pins, but if you buy a prepopulated kit from Chris M0NKA, this goes down to a few dozen rather simple items to solder.

Adjustment and Configuration

Before using the mcHF it is strongly recommended to run the appropriate adjustment procedures in order to have calibrated output, proper signals, etc. Don't skip over this section.

Recommended Modifications

Using the mcHF#

The following part provides you with information how to operate and maintain the mcHF. See this as an attempt to move away from the very nice manual made by Clint, KA7OEI, which you can find here. The document from Clint is based on a very old firmware version (0.0.219.26) and is partially outdated by our continuous work on the firmware. Still the document is worth reading, as is the quick manual but you should have a look at the following links first.

Explains which button / touch actions does what. Strongly recommended read!

Updating the firmware

Most of the bits that make the mcHF a radio are performed in software using DSP techniques. As such, keeping the firmware up to date is critical to getting the most from your radio. The latest code will be found in the git repository started by DF8OE, which also hosts this wiki. There is a single branch of code for the mcHF under active development but different kind of releases.

• Stable Releases: Newcomers and first time builders of the radio should use stable releases first. If the second part of the release version is an even number, it is a stable release.
• Development Releases: The newest features will be seen first in the active-devel branch. From time to time releases are made, either for preparation of new stable releases or in order to test new features with support of the community. If the second part of the release version is an odd number, it is a development release.
• Daily Builds: Bleeding edge code, this is where the contributors code is integrated.
• Other Branches/Repositories: Individual developers may contain code under very active development and may not even compile properly on every system. Those familar with open source projects will be familiar with the mcHF development model.

Prebuilt binaries including daily builds for the latest releases are available from https://df8oe.github.com/mchf-github/ . Older Releases are available using the "Releases" link in Github.

Contributing

The heart of any open source project is the contributions by individuals. Source code for the project is using git currently. There is a good explanation of github workflow here that is worth a read before branching and hacking on the code. And an online book written directly from the git creators you can find here.
