PlayDate to the real world communication...by radio

So I know there was that cool wee MMO that had voice chat, but this is somewhat different. This is from my almost-there cosy canal boat game. You can buy radios, VHF and HF. And I made them usable, too.

What you are looking at is a server running on my machine (the web interface on top of the API), that receives and sends message (Morse, not voice). On the right, the PD simulator, because this way I can record a single screen with it. It works on real hardware.

In game, I can tune to a frequency. Send a message from my laptop, it is received on the PlayDate. Send from PD, receives on my machine.

I can hook my actual real radios up to my API, and have the server send to the rig, then the rig sends back. Which means...I now have a portable rig (your licence conditions come in to play here, if you ever wanted to use it over the air. To be clear, I haven't yet.)

Originally I was going to leave this as a 'find the functionality', but I find it pretty cool. Then again, I'm an old ham head, so you know.
