Machine Learning, math and other cool tricks
What3words is an interesting alternative to sharing around long latitude/longitude numbers, instead share just a few words!
The first step to integrating the api is signing up for a free API key. Then require the library using composer – in the main project folder run:

This makes the app and repeater listing much more useful to those in Massachusetts, Connecticut, Vermont, Rhode Island, New Hampshire and Maine! This expands the repeater-START app and any other applications needing an offline, fairly complete listing of amateur radio repeaters worldwide.

Continue reading “Things to do while distancing or quarantined at home”The new Hearham live repeater listing has been up for one week and now has hundreds of repeater listings up! If you’ve been looking for a database to use for your offline app, this may be it! Unlike other repeater listings this aims to be up to date and allow for timely comments to go out to all users of the repeaters to know about any outages or changes.

This can get unwieldy after awhile. As I am adding a type for the open-source Hearham Live Repeater Listing, I will make a new node creator that will get the repeaters out of the api. So from what I had before, just one repeater code:

In fact, once you have a device set up correctly it is easy to integrate that (or any other command line features) into your project.
To start with I set up a class based on what I added for Hearham uploader – this will make the command run in a separate thread, continuing the process until it is killed. An ongoing process must not be on the same thread as the GUI (in any interface, Java, Android, or GTK…) This is going to use subprocess module as it can make it easier to use an existing utility (rlt_fm command in this case), rather than doing the whole signal processing in Python.

In fact it’s hard to find examples or documentation, if you look at the files of the package you can see there are some basic docs:
