Added a couple fixes to make sure to only use "is" when comparing whether two variables point to the same exact object, like when comparing to None, and to use "==" instead when we want to compare whether two *different* objects are equivalent.
Some frequencies are getting corrupted in translation to the 3-byte binary-coded decimal representation. Here is an example of the error when using the APRS frequency in North America. ''' aprs_freq = 144.39 aprs_freq * 100 = 14438.999999999998 int(aprs_freq * 100) = 14438 int(aprs_freq * 100) % 10 = 8 ''' You can see in the example the that last 9 gets incorrectly changed to an 8. By using the round() function, we can help the floats along so they don't mess with our frequencies. Here is an example of the fix. ''' aprs_freq = 144.39 round(aprs_freq * 100, 1) = 14439.0 int(round(aprs_freq * 100, 1)) = 14439 int(round(aprs_freq * 100, 1)) % 10 = 9 ''' Now you can see that the last 9 stayed a 9.
I couldn't find any specific documentation, so these updates are largely just from playing around with a Yaesu FT5DR. I added a few channels to memory manually on the radio, then saved to a microSD card. Then I started using this tool to parse the MEMORY.dat that was saved to the microSD card, and export the parsed data to test.csv and test.dat files. Using xxd and diff, I kept making updates until the data was as similar as possible.
Update the CSV format to match Repeater Book's Yaesu FT3 ADMS 11 export format. It seems this format might have been added to Repeater Book after this tool was developed, but I'm not exactly sure on that. Anyhow, the goal is essentially to be able to export from Repeater Book and then use this tool to create a MEMORY.dat that can be loaded onto the radio via microSD. There are more fields and they are in a different order than the format this tool was using, but one of the benefits is that we can capture more of the data fields so that we can import and export without too much being changed the process. Repeater Book documents their Yaesu FT3 ADMS 11 CSV fields at https://www.repeaterbook.com/wiki/doku.php?id=yaesu_adms_11.

Hey there, I was just playing this weekend working to get a Yaesu FT5DR radio programmed (without needing to get Windows set up and potentially working with buggy Yaesu apps) and came across your repository. Thanks for hosting it, it is pretty much exactly what I was looking for! 😄
Going through everything, I ended up making some changes to fix a couple warnings and and an issue with float precision that was dorking the frequency values. But the real goal was to be able to export from Repeater Book and then use this tool to create a MEMORY.dat that can be loaded onto a microSD card to program the radio. So I'm also submitting some changes to update the CSV format to match the Repeater Book format for Yaesu ADMS 11, and to change some of the data values to match what I saw on the FT5DR.
Thanks again!
