A Meshtastic Firmware with APRS would be perfect. And then a ATAK Civ Plugin to have great connectivity in off grid environments.
Interesting project, thanks for sharing! Now I'm waiting for someone to say in the comments that it's pointless and that for the cash they are better off buying a 'proper' handheld
There has already been one of those comments! lol…. Cheers
Very interesting stuff from perspective of a licensed ham-hacker especially. This shoudl keep the brighter kids around a bit longer :)
Amazing
OpenRTX is involved ... They have some good people!
Excellent software devs, indeed!
VERY cool!!!
Man I need one or two.
nice
Refreshingly meshtastic free - those were the days... I now have 5 meshtastic devices running.
wow if there are some really good projects for these I might have to snag two
What is the aproximate distance / range ? If it was in the video, I missed it. Is it generally longer than LoRa ?
Hi, thank you for putting this video out. Looking forward to get APRS working on this TTWR+, any chance you can let me know where can i download the 3D printed case ? Cheers
I was also considering using this for APRS, especially since it has onboard GPS. Have you had any progress?
When someone makes an opensource DMR code for that (assuming no hardware problems) that kind of platforms will be killers. ..with enough output power and harmonics filtering of course.
Yea, only to speed up the transition from DMR to M17 :)
BTW, there's a problem with AMBE vocoder legality.
Unforunately, the AMBE codec is not open and you have to license it.
I can't seem to located the STL for the swanky case in you video - can you share the direct link here ?
How much power does it put out?
I want a 1GHz and a 2.4Ghz version to explore the frontier of ham radio.
At lilygo store it is less expensive than Aliexpress
Been struggling finding the CTCSS list to convert the codes to frequency tones. I think I'm just being daft.
Oh, I was about to ask how that CTCSS work with this device
what range does it have?
Nice! Hopefully there is or will be a version with a full color LCD rather than this monochrome one.
I have both types of those tiny LCDs... well, 3 kinds... one color, 2 color and full color.
I love the full color ones and on occasion will use those. What can I say. I love color and do shy away from anything that, now in 2023, doesn't go color. LOL
Sure, I get it. A minor thing for most, but some of us love to use colors to enhance a project.
You do have a power consumption tax to pay for that color tho and i suspect battery life is a bigger priority for most on a handheld radio.
Hope someone ports NPR 70 into this
This this work with meshtastic
I guess you can finally make an M17 radio by software
Yep, check out my other M17 videos where I show using the M17 Tools Gui app.
Could this be modified to be a satphone or connect to the iridium network?
Most likely - no.
Needs a little more explanation. What is this thing? Other than the possibility of using it as a walkie talkie...what else? Why?
Do some research on ESP32, SA868, Wi-Fi, Bluetooth and GPS. Then think of an application that uses any of those components. Then build the software. For example, an APRS tracker or iGate could be made all in one unit. Possibilities are endless. Take a look at SoftRF that I linked, they have lots of Aviation projects.
I would be extremely cautious about transmitting on the frequencies listed. Most of those require a license.
This is not a digital transmission so no security
Not my style
For the price better buy a cheap Chinese walkie talkie
Think you’re missing the point of what can be done with these, of course one would have to have the knowledge or the capacity to learn programming etc. I can recommend the UV5R for you sir.
@@TechMindsOfficial for the learning i can also buy a esp32
Or a new t-beam
its not the same thing, and not the same target audience. If you dont like tinkering, coding, soldering - then by all means go buy your chinese "walkie" - if you have no ham-radio license, you would not be allowed to "tinker" anyways.
@@zoolkhan this is can also transmit in ham radio bands
Hamshield was a far cheaper and much more versatile rig to play with. Too bad it didn't sell much.
Unfortunately Hamshield was shite! Great idea, but didn’t work as intended. I have one, for a long time, but it has problems and the people that sell it don’t respond to support requests.
@@TechMindsOfficial They became Inductive Twigg and died during the COVID years. I've built a few of them and they work OK.
@techminds I received mine today and is that anyway to tell from the box if it’s the open edition or plus? De KE0LFX
Not sure about the box, but I am pretty sure it doesn't come pre-loaded with the Walkie Talkie style app if its an open edition.
Great , i tempted to buy the uhf version! 73 de iz3qvb
