Text chat is an obvious application as is MQTT. With MQTT you can publish sensor data to an Internet server where another computer can subscribe to those sensors to monitor the readings. Control instructions can be sent back by the same method. It's dead simple and low bandwidth. The advantage of this over say an outdoor WiFi link is the signals from these radios carry much better. What ever handsets can achieve without extra antennas is what you can get these to do TCP/IP. If one was a proper base station with a decent antenna and Internet connection you've got yourself a wireless WAN with many applications especially in remote areas where you don't want to use the mobile network.
bingo, seriously considering this system for an open architecture fixed wing SAR UAV. we have problems with people taking over control of rc planes and drones in my area.
That's hilariously good. You could do a lot with that since you have TCP/IP layer4 connectivity via UHF/DMR. Looks like about 300 baud, which I actually used in the late 1980s. Very cool.
@@andykirby Can’t wait to see it. Yourself and Lewis’ channels are goto for radio info. And I do watch all of your videos about the other stuff as it’s really interesting.
@@M0LHA yeah don't think the 7100 would be able to do it unfortunately, great radio though. Still have mine. Remember to try and find a Motorola, not sure if the others will work.
Another great video. I wish more was around regarding this sort of comms. Is there something out there along these lines that are completely cross platform (Mac, Linux, Android and Windows) that would work on most radios, ICOM, Yaesu, Kenwood and maybe even all the way down to the humble beginners friend, the Baofeng UV-5R etc? Thanks for posting.
Me and a mate did something similar to this about ten years ago. Pi1, tnc and baofengs. Fsk? . I managed to ssh into the pi at the other end! It took forever. Tcpdump at the same time and you can literally follow tcp doing it's thing. You could also hear ping and echo reply with their own distinctive tones. Lol
Haha cool experiments! It's quite interesting what you can do! The old packet system was very efficient with its tiny bandwidth (1200baud) as doesn't do any network intensive stuff like modern tcp/ip.
@@andykirby yeah that's it, it was 1200baud. Pretty useless for most things but fun to expirement. We did try to use NC to transfer a file, but that was a massive fail. Over 4 miles as well!
As ax25 software is concerned, most of the end user programs were developed in DOS or Windows. As the interface is using a standard tcp/ip you should be able to use any point to point chat software. However you would need to add emulators to run the native ax25 programs like TsThost, Winpack. However you'd be better sticking with native tcp/ip and keep the overheads of crc to a minimum. As you noted there was quite a lot of chatter between the two radio's to transfer the 8kb text file!
You can do this with D-Star radio's too, although it's just a serial connection, not ethernet. Speed isn't anything to scream about, but I've had file transfers going through it without a problem.
There's a bit of a packet resurgence at the moment - lots of TNCs coming out of storage and people using newer NinoTNC boards. That's more the analogue side, though.
I have an issue sending a ping to anything behind the radio, Its like it needs a port open. I found a Motorola document that says that you need to ping the IP address of the USB peripheral network. (CAI +1) however this doesn't seem to work. I can ping the remote radio fine. Any ideas?
Hi, there are anywhere docs about requirements: DATA Digital config, IP config, etc... for connection between the pc´s and the radios. I have two dp4800 and we are not able to stablish connection between them. I were triying from the first Electronic Noob video. Could you help me??
Drats is pretty neat but I only ran into one other person that used it. There is a way that you can use analogue radio but that was a read back when I first started. I think it's at eol
Oow now you're talking , I love this stuff. Ain't got anything on my trusted uv-5r though.. or my lovely Radio Shack TRC-222 40 CH Citizens Band Transceiver. Lol.. yeah I know, I need to get out of the 80s. 73s xx
been doing that on CB for 30 years + The Germans had a set up in most schools in the 90s to teach computing... aprs system still going but smaller network now..
Hold on- does this mean that it can route data over a few radios? TCP/IP is layer 3 which means this layer can connect two nodes which are not physically directly connected. So say I was on the third floor of a building, one radio on the second floor and one radio on the ground floor. My radio can't directly contact the radio on the ground floor, but can route my data through radio on the second floor. I wonder if this is achievable with MotoTRBO
I also want to know - I have an Anytone as well and would be interested in getting this set up. I suspect the radio itself needs to have support for acting as a network interface over USB, and my guess is that these don't sadly :(
