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.
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!
@@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.
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!
@@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.
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.
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
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.
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..
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
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??
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 :(

Great proof of concept Andy, I could see applications in Emergency Communications with small file transfers of forms working.
Please connect both radios with USB cable and run iperf command 😊 to see the throughput 😏
YES. 128kbps lol
@@jamess1787 hopefully will be higher on UDP
Please do this
@@catalinalb1722 🙏
OK will try. It's gonna be slow. Some company made a UDP file transfer with packet error handled by software, apparently its quicker.
That's very neat you have a TCP/IP network and a normal push to talk at the same time.

Oh that's quite cool. Wouldn't mind giving this a go in the field - just need to pickup a handy. Wonder how it would operate on 2m
Yeah do it. It'll probably work quite well on 2m with a good antenna!
@@andykirby Looks like I'll be poking around the internet for a DMR set. I don't think my IC7100 has a virtual data modem. Thanks for the video

Keep the videos coming Andy. I also enjoy your TikTok and saw the latest video about the packet radio bbs that you received on the icom.
Thanks Paul. Yeah I've got a video coming about packet as well 😊

Excellent and very informative video! I wonder what kind of range you can get with packet vs voice.
Nice stuff Andy!
I'd like to see the developer of d-rats pick this up. Similar concept used on dstar. I'll definitely be experimenting with this. Thanks for the video!
Yeah thats what I thought :-)

@@andykirby yes we like to give the old "ham" digimodes a thorough test in marginal conditions.. lol
Interesting demo. But I was wondering: how did you know the 13.0.0.2 address? Sorry if you covered that; I missed it.

Ha, I used to run packet over an Icom IC2E handheld. I could never understand people wanting to use this Internet thing with expensive dial up :-)
😁😁😁 bring back packet!
I wonder how long to send the Native Instruments library from one Mac to the other using the radios 😀

Have you been able to connect to three or more devices? Like a group message?
Can you talk between DMR radio to analog radio? and can I get a DNR I'd with a GMRS lic?

Hmm... packet forwarding isn't built into the radio but when connected to a computer of some sort this would be doable I think.
@@andykirby Interesting stuff... Do you know if Hytera DMR radios are able to do TCP/IP?
have you looked at the gotenna devices?
Hi Andy. I see you have to different Motorola DMR radios there - which models are they? 73, Jan Henkins (M7HNK)
R7 and SL4000 👍🏻
Is there any way to do this with other DMR radios? (e.g. Anytone)
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 :(
Do u need license for dmr
you can't buy those radios in the states
