Create RF Internet connections between two radios

Let's leverage the IP/internet protocol between two radios, using AX.25 as our transport. Ping, telnet, web, IRC-chat, anything you can do between two hosts on the internet (aside from encryption) can be done between two Amateur radios over RF. Ping times measured in seconds. Bandwidth measured in 100's of bytes. It's slow, sure and fun! Create reliable internet connections that span 100's of miles over RF. This is the essence of re-imagining amateur radio data modes in the information age.
Thanks to @Streets and @Frozennerd for the inspiration for this on DigiPi Discord!

Extremely well done and thank you. That said, its time to petition the FCC to permit some level of encryption.

[@isthisoneunavailable]

I understand the sentiment against encryption as it's an espionage concern. That is a legitimate concern, regardless of if uncle Sam demanding to listen in is frustrating, which is a sentiment I agree with. That being said, no reason you couldnt have encryption with a key you also give the fcc. While they can still listen to what's going on, only (hopefully) they can, which is an improvement nonetheless.

[@acherrington]

@@isthisoneunavailable you have the same issue with high speed fiber and overseas cables.

[@Subgunman]

NEWS FLASH! Uncle Sam can intercept and decode many of the current encryption modes. Nothing is private on the air.

[@ericjx]

@@isthisoneunavailable Not exactly sure I understand that type of concern in this modern age. You can communicate to literally anywhere in the planet in today's age, instantly, fully encrypted. This seems to be more a legacy law, and I imagine hams spend more time trying to fight the idea of allowing encryption than the gov't would.

[@isthisoneunavailable]

@@ericjx that requires infrastructure. Ham doesn't.

Great video. A dedicated video on AX.25 is a great idea. - Thank you!

[@erichexter6631]

that lick was from natural science :)

[@devinhedge]

Yes it was. One of my personal favorites off the Permanent Waves LP. The irony here being the second riff was from "Don't Fear the Reaper" by BOC. Rush opened for BOC when Rush was on the Kings tour (1978). BOC opened for Rush on the Power Windows tour.(1986?)

[@jakelarson9935]

Awesome! I'd love to see a ground up configuration of AX.25. I feel like I'm missing some basic stuff that's holding me back from really understanding it.

[@dperv27]

Great video!! Always enjoy IP over RF. Have you thought about demonstrating 2400 and/or 9600 baud links. How about integrating IL2P with legacy AX.25. Also, D-Rats works over AX.25. (Just a few video ideas(

[@anthrounit]

A need to change the laws with the FCC encryption should be a given.

[@DonzLockz]

A great project to test but so much to learn in ham radio. I'm very interested in digital modes so this is a must.🍻👍

[@therfnoob7697]

Super cool! Great video. Although I think the IRC protocol is too inefficient (especially the server side) over the air (broadcast channel). The problem is: Alice: send message M to Server Server: receives M from Alice. Server: forwards M to Bob, Server: forwards M to Carl Server: forwards M to Dave, .... Server: forwards M to Walter If 1000 users are connected to the Server, the server would have to transmit/forward 1000 messages for each message received, and would basically occupy the channel. Of course this is terribly inefficient, since the broadcast airwave channels would allow for just 1 "forward message" to be sent at once, and received by all users.

[@streets814]

To be fair I haven't been on a net with or an active irc channel with that many users.

[@DanGeesky]

Amazing content, new sub here. This is so good, please! could you do a tutorial on how you setup the IRC stuff from the ground up. I'm looking into something like this but have no idea where to start.

[@devinhedge]

Nice Rush reference.

[@Rickm505]

In the early days of commputer modems 9600 baud was cutting edge. Higher thruputs we acheived adding compression to files. Where's your compression?

so?

[@alekzandermaniku4630]

Hi, this is very interesting information. I am a ham operator from Bulgaria. I have enjoyed radio and networking from a very young age, and I am curious about what would happen if you tried to play a video, a song, or even connect to a non-encrypted Minecraft server. 😂 Would it get overloaded? Also does digipi software include built in wifi hotspot?

[@KM6LYW]

No, I wouldn't even try on VHF (144Mhz) which is supporting 1200baud. Maybe at 9600baud, which is the logical limit. it might take hours to transfer a song.

[@alekzandermaniku4630]

Interesting so it’s quite slow technology is there a way to speed it up to get let’s say 1 megabit per second otherwise this could be practical for off the grid networking for basic information

[@craig9309]

@@alekzandermaniku4630 No, it's a function of the frequency. Lower frequencies go 100 miles, but the bandwidth is 1200baud. High frequences go across a house, and the bandwidth is 1 billion baud.

[@alekzandermaniku4630]

@@craig9309 how high frequencies give more speed and is there a balance between distance and speed?

[@ManuelPinner]

How about connecting a Pluto Plus to a IC 705,

[@vzivadinovic]

705 is incapable of 9600 baud if I understand correctly....

How did you connect the yaesu ft 2800 to the raspberry pi?
