Foundations of Amateur Radio #197

What's in a Chirp?

On Thursday the 3rd of July 2008 at 6 minutes to 7 at night a
developer called Dan KK7DS started to scratch an itch and published
the results. The next morning before breakfast Dan added more. Since
then about a hundred people from around the globe have contributed to
that project.

Some people made little changes, others made large contributions over
many years. In all, on average, the project saw a change every 29
hours over more than a decade of contributions.

On the 16th of July, less than two weeks into the project, it got a
name, CHIRP. It's been translated from US English to Spanish, French,
Hungarian, Italian, Dutch, Polish, Brazilian Portuguese, Russian and
the Queens English.

>From the beginning of talking to a single Icom IC-92 radio, CHIRP
today supports 27 different Icom radios, 36 different brands of radio,
hundreds of different radios in all, with new ones being added every
couple of months or so.

The software runs on anything that will run Python, that includes
Windows, OS X and Linux and it does it with an extremely modest
footprint and it's free, free in cost and free as in Open Source.

If you're not familiar with CHIRP and you have a radio, then it's time
to get to know this tool. It makes it simple to program your radio, to
configure settings and to make backups of your current channel
listings. I should mention that this is not just for hand held radios,
there are plenty of HF base station radios supported.

When you run CHIRP it presents you with a window where you have a
spreadsheet view of the channels in your radio. You can download the
channels from your radio or upload new ones. Changing a frequency is
as simple as clicking on the frequency and typing a new one, with a
full-human-sized keyboard, rather than the poor excuse for a dial-pad
your radio has. If your radio supports it, you can supply a human
readable name, configure offsets, CTCSS and tuning step size, the mode
and several other properties.

If you're unsure where to get started, CHIRP even comes with a list of
frequencies to get you on your way.

You can create different configurations for different types of
operations. For example, if you're into SOTA, you can make a
configuration file that has all the relevant SOTA frequencies, but
when you head back home and want to use the local repeater network,
you can build a set for that. If you visit a different state, another
country, or if you want to copy your channels from one radio to
another, you can with CHIRP.

If you want to get started, there's a Beginners Guide, a list of
frequently asked questions and you'll find information about what
cables to use, specific errors and issues you might encounter and if
you're a software developer, you'll find information on how to
contribute.

If you want the ability to program your radio on any computer, you can
download a boot-able CD that will run CHIRP without installing it and
if you need help, there's an active mailing list, going back to 2008,
an up to date wiki, issue tracker and of course, you can download the
source-code, if that's your fancy.

CHIRP makes all that possible because one amateur wanted to scratch an itch.

What's itchy in your life?
