Balloon Payload Package

I have been working on another balloon payload package. This time it will be based on a TeensyLC MCU and transmit on HF radio using the 10 meter band with telemetry encoded with FT8. I am just getting the basic design worked out now but my working code is uploaded to GitHub HERE.

I spent a bit of time figuring out how to generate a 10 digit Maidenhead Grid value. The details of the Maidenhead Grid system on THIS GitHub page were very helpful. My Maidenhead Grid code can be directly accessed HERE.

I hope to do testing with the payload package with a kite and then a balloon launch by summer.
