Rattlegram: Messaging on a Quansheng and Baofeng. Can you decode the secrete message?

[@sUASNews]

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.

Nice, haven't heard of Rattlegram. Thanks.

Thank you. Have a go its good fun

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.

Or maybe have a look at meshtastic.

[@LeeMcc_KI5YPR]

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.

[@patric001eede4]

@@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.

[@patric001eede4]

@@LeeMcc_KI5YPR Nah. with LOS and default settings you can fairly easily get 100km. Check the forums.

[@patric001eede4]

@@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.

[@markphillips8019]

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?

[@deadbeathusband471]

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.

Good Idea. I'll have a go at it and post the results
