I love #aprs. A simple, known technology build upon established protocols is amazing. Having this infra available universally everywhere is cherry on top. Yet under somewhat perfect conditions performance ax.25 giving is sad. This is also my first maritime #amateurradio ops. Not being able to reach digis that I hear was frustrating but texted with @ooguz at least.

@alper @ooguz You could try to get relayed by the ISS as a fun experiment. It looks like it's operational:

@kr1st @ooguz It is also on my mind at some point yet boat is not mine and my stay is short. I only set this up since I had to kill a lot of time during night navigation =)

@alper @ooguz I've been wondering for quite some time if there's another protocol that solves the deliverability issues of AX.25. I have been trying to receive packets from the tops of mountains and I haven't been able to decode a single one.

I want to make my own arduino digipeaters (small, cheap, low power) but the protocol has to be simple enough for mortals like me to implement. Not sure if Ribbit is too complex for that.

Any experience with FX.25 in your area?

@winduptoy @ooguz FX.25 claim to solve that issue with backward compatibility yet non exists where I live and my radio (th-75) doesn't implement it.

I happen to stumble upon a project using stm32 board to create modem/repeater which also have fx25 mode. Perhaps a cheap usb-c powered radio with that board is the way to go. I plan to experiment with that but did not had time yet.

@alper @ooguz Fancy looking boat. Amphibious too, by the looks of the track! 😉
