X.25 Frames with AFSK Modulation

A code sample is now available in the Brandenburg Tech GitHub repository. This sample generates simple AX.25 frames modulated using AFSK (Audio Frequency Shift Keying). While AFSK is usually used at VHF frequencies, this example uses a UHF frequency as that is how the matching network is configured on the Digital Transceiver for the Raspberry Pi.
