I'm going to add my 2 cents. For tactical purposes this will work well and minimize the chances of being located by direction finding. For emergency coms, this is just another option in the tool kit. So my protocol has always been (listed in order of use) cell phone, text message on cell, vhf/uhf radio, hf radio, morse code on hf, aprs includes rattlegram and finally meshtastic. I put together the radios, meshtastic, portable power for about $150.00. I did this over time. For immediate needs get VHF/UHF radios, for no license get FRS and or CB radios, For more power and a $35 dollar no test license get GMRS radios. In the final analysis if it is a life threatening emergency key up anything you can get your hands on.
All three messages received. Thank you for this video. Question: Is there a way to turn off the microphone used by Rattlegram and only turn it on when you want to use it? I am unable to find a setting in the Rattlegram app
My portable radio, IC-7000, does not have a tuner, so terrible antenna for me. 😂 I stick to resonant in the field. Mostly CaHR Apollo (40-10m) and I linked 20m more wire to pick up 80 and 12m. For reference, my shack antenna is a resonant off-center fed dipole, all the bands 80-6 except 60m. 30m needs a little help but the shack FTDX10 can handle it.
Meshtastic works in some applications, but it requires a mesh. The range can be good (anecdotes of 20 miles) with high masts or line-of-sight hill-to-hill. 2m is not usually long range, but better gets through terrain. Of course, using the Amateur frequencies on Meshtastic means more power is allowed in the US. I believe other countries are the same.
@@LeeMcc_KI5YPR Some basic range-tests have shown links of 150-200km using a basic T-Beam's and staying within legal TX limits and having LOS or almost LOS. LoRa seems to be less affected by things within the fresnel zone. Ranges are for direct node to node communication. Go check the Meshtastic forums. Quite a few range tests available there. And no, a mesh is not strictly required but it allows traffic to be repeated for an even larger area. If we have a look at plain LoRa there is a record documented on Hackaday of 1300km (830 miles), but that was over the ocean. With a good mast you reach quite a bit further than 20 miles. With a basic antenna but LOS you easily get over 20 miles.
Yet another "packet radio" wannabe. How do you move messages down a chain? How do messages get routed. What about error correction? What's the max channel usage?

Thanks for your comment. your final analysis is so very true.
Nice, haven't heard of Rattlegram. Thanks.
Thank you. Have a go its good fun
@@G6PNH I will.
Meshtatic and ATAK is a good combination as you can also use the hammer plug in with ATAK that does just the same as Rattlegram.
WOULD LOVE TO MAKE IT TO THE EAST LANC RADIO CLUB, BUT A WEE BIT LONG FOR THE DRIVE... I'M IN MINNESOTA.
THANKS! 73!
Brilliant reply thank you. You would always be welcome if you ever do visit the area. 73.
Bacon butty night every 3rd Thursday at the East Lancs Radio Club
@@CodeBrownProductions brilliant yes well done

You welcome and thank you. I cant see an option in the app but you should be able to turn it of through the permissions in your settings.
Many thanks great idea - 3 message: "Bacon butty night 3rd Thursday at the East Lancs Radio Club"
Congratulations you are the first

@@LeeMcc_KI5YPR Nah. with LOS and default settings you can fairly easily get 100km. Check the forums.
@@LeeMcc_KI5YPR Real-world tests shows 150-200km with fairly basic equipment and staying well within EIRP for the unlicensed band.
@@patric001eede4 Do you have a cite for that? I am curious about conditions.

It's not meant to be like packet radio. It's for transmitting short messages quickly, and it actually does have pretty powerful error correction.
Got them both! Thank you for the presentation 73 de SV1SLB
Awesome KN6JHC
Very good, now to try it with vox.✋73's🎙KD9OAM🎧
Good Idea. I'll have a go at it and post the results
