Start with a proper receiver like an RCA AR88D, yes it's heavy but it will do a proper job. Plugging a device into a USB port on a PC will teach you nothing useful. To receive anything useful you MUST have a decent antenna which a proper receiver hill have provision for.

So it's APRS for messaging?

Man i can't find a knob that'll glow anywhere, theyre all opaque and im too poor for 3d printing 😂 its frustrating

Thanks 👍

This might be the best ‘antennas for newbs’ video I’ve run across. You explain a lot very concisely. Nice job.

i think the menu is unnecessarily abbreviated because the basic programming/firmware for all these chinese radios is basically the same, they are too lazy or dont know how to reformat the text

How long did you have to extend your antenna for that transmission? Jw.

Can I program the Quansheng UV-K5 to keep within the legal limits? There are a few stories, it may not be within EU standards. Is this also your experience that it can't be used with -60dB, only stronger? Very interesting video! Thanks!

I wish there was an APRS that didn't have all the ham radio guys there

This is only about the 4t time i even heard the name of this gadget. So if a few ppl was camping or working in the desert or Forrest. Each group in theory could use a helium balloon to lift a node to about 50 75 meters possibly teathered by a kite string with a possibility 30 gauge enameled copper wire for grunding and possibly mounting te antenna to. Maybe use hydrogen in the balloon, produced from water and a solar panel. With say 5+ groups of 2-4+ ppl. Say 2-5 miles apart. This could allow basic communication between them each group having a node close by (roughly 150' high) possibly a central node in a Forrest location with tall trees. They should have good comms . Especially in a desert location as long as the nodes can see each other, and the people on the ground can see a node. I can see this being awsome with some improvements relax regulations slightly, with a 8-10 watt Maximum (and 2watt buffer) an a slight change to transmission protocol. Have a short term memory to store messages if they can't be instantly transitted. Have the messages lined up like the start of a race , one goes, a few seconds later the next, then a few seconds then another, possibly receive messages before transmitting the next. Maybe a received confirmation signal. Then the next transmission to prevent lost messages and congestion. Maybe divide into channels by the frequency of the message how fast the message itself is sent. Like talking faster and slower. Wth the same volume. Say the two channels. One is one word/sec. Two is 2 word's/sec. Actually much faster with not such large difference in rate, but the system programed to seperatethe two. And what abut transmission over CB radio frequency?? Sorry to ramble, havea awesome day!

What is the meshtastic like shortwave system called? I’m interested in meshtastic coming from ham side but am more interested in HF shortwave even though to me short wave isn’t HF I’d rather a system like meshtastic that can travel even further between nodes

Would it be beneficial for APRS to adopt a modern chirp modulation? This would improve range and reduce required power.

Fantastic video - thank you for your work putting this together. I plan to share it with non-hams who ask me about getting into radio.

Dont forget on HF Amatures use between 160m to 10m not just 80m to 10m bands plus all modes but more frequently cw usb lsb rtty

Would you recommend the Xiegu X6100 or the X6200 (when it comes out) as a first radio? I live in an apartment and don't have much space. Thank you!

Good video

i got the p1s, my gold pei sheet refuses to hold prints like it did when it first came out of the box, i have washed it with dawn dish soap and followed their exact guide on how to clean and no. im at a loss because my return policy JUST ended and then this happens lol

show me how

But can it play DOOM?

Is the The Clifford Heath edition better/newer than the 2024 R10 version? Which is better? What version is the The Clifford Heath edition based upon?

Excellent job! A long-time Elmer.

I got a boafeng long before I got a license. But getting a license gave me a good foundational understanding of RF which changed everything for me. Now I'm learning YSF finally

Excellent introduce to the topic ❤

Just ordered mine after years of wanting one. Thank you for the info!

Great video! Thank you for this fine effort!

The downside to APRS is the HAM license requirement. As where LoRa can be experimented with by us unlicensed plebs, lol. Now that being said, APRS, by virtue of its design, is FAR more capable. And.. I think i'm going to have to end up getting a HAM license at some point. My mother got hers back in.. 1990 I think? So I've been in and around the space for at least part of my early life.

I love radio of all shape and size, I should get a ham radio license.

La música culera era necesaria?

Great content!!

Excellent video! Thank you for creating and sharing! ❤

You should check out rnode instead of meshtastic.

Both tools are completely different. The flippers used for IR, Ibutton, subghz, and RFID. The hackrf, while capable of recording a signal, is a traciever designed for radios. A flipper and hackrf save files are not interchangeable that I know of. At least not out of the box. The big brother to the Flipper is dependent on the frequency. That could be a small usb dongle for IR, a microcontroller, or an FPGA. The big brother to the hackrf are it's individual transcievers, which each have their own solutions.

Great video thank you!

“Hobby Radio” is not a great name either. I like “Experimental Radio.”

Some of our points about Meshtastic are valid, but I think your missing the point of It. Its really designed for small groups as the max nodes supported is pretty small. Think emergency communications. Sure, you could do this with APRS, but that requires a license, has no encryption, requires more power, more batteries and a much larger footprint if your trying to stay low-profile. I agree that Meshtastic is more of a local area mesh network, and APRS is at its best in larger metro areas where the added xmit power (5W and up) can really reach out. Then add mobile APRS to this and its pretty powerful. But again, no encryption. Every message is available for anyone to read. This is not an option for a lot of use cases.

Without using any WiFi or radio connection 😂😂

Range?

Another great video. Another comment just to promote your hard work within KZfaq algorithms. Love it, keep this going!

These appropriately should be combined with a mainline linux kernel and crippling the firmware to the cellular radio or else the android phone will just exfil the data at some point possibly

That is beyond cool. Seeing stuff like this that has applications for prepping but also military is awesome. Thanks for sharing it with hs

I tried doing this transmitting from my HACKRF to my flipper zero and the signal strength was pretty weak. For me, you’ve got to be standing within 3 meters of the device in order to pickup any signal… 🤷‍♀️

yo you got the same wallpaper as me

Where can i found one? Just the pwnagotchi, i can't find it anywhere :(

It's not off grid if it works on another grid.😂😂 You can call it mesh, lattice, framework, network, grille, reticulum.

an actual full custom firmware of any modern phone would be superior in every way

Sounds like the old Nintendo game Russian Attack 🤣

This video needs more love. Good job bro

Interestingly enough, Meshtastic is preferred for ad hoc communication among hams in many scenarios. For example, at Dayton Hamfest this weekend, even with all the licensed hams, Meshtastic traffic among them is greatly exceeding APRS traffic. One factor is that most devices doing APRS are far more cumbersome for messaging whereas Meshtastic and phone provide an easy and familiar interface.

You pick up the people where most of them are :-) Very good explained! (Just 2ct from a Dipl.-Ing.)

Another excellent video! That lesson was not only concise and informative, it was well produced and interesting to boot! Love and appreciate all your content. Looking forward to more! Thanks!!
