It would be useful if you would vover this camera with some different kinds of obstacles to see how it differs

Luck for you. I got a bricked thinkstation P720, resetting BIOS jump doesn't work, only get 3 short beepings. No Luck

This meshtastic thing is so frustrating, i get nothing locally and i followed the advice in the video still nothing 😤

@Simon Phillips No PI3b? tried it on arm64 and libyaml-cpp0.7 let me down on the dependency , not only that i tried pointing to /boot/config.txt as i never had /boot/firmware/config.txt . i cannot install meshtasticd .....meh ive run out of pi4 but have a load of 3b+

Could it be that the Tiny SA was showing -db errors because of the noise floor (-28dbm from tiny SA with the -40db attenuator)?

Awesome tutorial! Thanks! Was wondering how to do this.

What is BBS software?

I did the same, repladed normal bulb to LED. Now the lamp emmits some fluorescending light even when switched off. Why is this?

Great video and experiments. Thanks a lot!

Miniwhip is a PROBE for the electric field not an antenna. Conductive objects modify and reduce the electric field so it must be installed in free-space. So the miniwhip is sensitive only to the electrical component of the e.m. field: this is its main advantage because man-made structures or trees absorb the electric field much more than the magnetic one and therefore, if mounted correctly in free space (non-conductive pole of at least four meters) it will receive less disturbances than a small diameter loop or a long dipole and generally provides a higher signal/noise ratio. The original project is calculated to work conveniently from a few kilohertz up to about ten megahertz. An antenna to be defined as "long wire" and behave as such must be longer than one wavelength. 73s.

🏆👍🇧🇷

Duuuuude. That’s neat.

Nice clear information I got mine working today

Thank you... much appreciated.

Good job 👍 I just ordered a t deck to play with

Supposedly has a design change in the front end filters for the newer ones, but I’m very happy with mine. No problems, works for me very well. I like the 330 too, very solid little unit. Thanks!

The tuning noise is called "soft mute". It is the bane of many DSP receivers. It is very irritating.

We’re here for the antenna and you go off on a tangent with a spectrum analyzer

ok made it this far and not getting same results sudo systemctl enable meshtasticd --now i'm not getting the return message you have 22:03 WRDX849@MeshNet:~ $ journalctl -u meshtasticd -f Aug 24 11:20:47 MeshNet meshtasticd[3347]: INFO | ??:??:?? 10 SX126x init result -2 Aug 24 11:20:47 MeshNet meshtasticd[3347]: ERROR | ??:??:?? 10 Failed to find SX1262 radio Aug 24 11:20:47 MeshNet systemd[1]: meshtasticd.service: Main process exited, code=exited, status=1/FAILURE Aug 24 11:20:47 MeshNet systemd[1]: meshtasticd.service: Failed with result 'exit-code'.

Hello, how can I install STL-SDR V4 in console V3.0?

Hi, doubt here, hope you can help. Do you see those lights turn on with human eye or just with the IR Filter as you shown? i want to put one outside but i want it to be discrete not a spotlight :)

Thanks for showing us how to do it but it was super annoying showing us the wrong way to do it multiple times first lol. I'm trying to follow along and do it and you're like just kidding that's wrong

I have no HAM background, so this helped calibrate my exceptions of how to get better signal with Meshtastic. If anything, it kinda sold me on the VNA and TinySA to make sure I'm getting what I paid for.

interesting, i made an air-choke for my cb antenna following 'G3TXQ Common-mode chokes' guide but would be interested to be able test how well it works.

Excellent findings as always , ground breaking & thank you for sharing .

I installed sdr console but once I start my sdr Duo I still don't get any singal. My sdr Duo does work with sdr uno. Thanks. N1CM

I am using SDR Console....I wanted to use to track satellites. Using with RSPDX-R2. It works but I get no antenna selection. I have the SDR Play API installed and I added SDR Play in definition to "replace" but it it still shows an "unknown" device although it sees the serial number. Rebooted, replugged in device, same problem. Now after I restarted, it will no longer track frequency at all, it just stays on the same frequency I have to manually enter. Any suggestions? Tnx, I am new user to SDR Console, I like how it has the plugins built in to software.

Hey Simon, I have an issue that you might be able to help me out. I’m using my rak4631 with usb connection instead of bluetooth, but seems like the phone looses serial connection after some time, the phone seems to loose connection but the radio still operational, any idea of what could be happening?

I am trying this with a pi zero 2 but getting errors. No luck yet.

curious if you’ve run into the bug where you can’t send longer messages. Short seem to work fine but anything over like 70 characters seems to fail.

Hi Simon, do you have a github repository with the code? I have the same module but I'm having some trouble to configure this. Thanks!

I have set TT02 on Medium Fast. I'll put it outside when it becomes fully charged.

Nice new practical take on RF - great to see the demonstration of interference fringes and polarization. Would have been interesting to see the effect of ground planes and where possible a reflector. Thanks.

would this work on an r-pi?

You make the best Meshtastic videos between Munich and Brighton! Thank You! Timo, DB1TK

Wow

do i need that battery without gps modul ?

as you say, arguably can be written off the sma's that can be upcycled for other projects... Not sure who got the video out first re these, you or Any Kirby as youtube says both were 4 months ago. Cheers

"loved your drumming work!" First reaction when I saw the 239 connecter in the placeholder in conjunction with Meshtastic I had bit of a raised eyebrow moment, but "what was at hand" ... I'd have done same. Amazon sell 5 packs of similar configuration chassis SMA for 16quid. "Superbat SMA Connectors SMA Female 4 Holes Panel Chassis Mount Flange Solder Cup Connector SMA Bulkhead Connector 5-Pack" Chuckled when you showed your fave' antenna, at first glance it was very similar (but not the same as) Andy Kirbys dodgy one - the youtube placeholder pic says it all :- ua-cam.com/video/Y4qXn_gOTY8/v-deo.html Good video, many thanks for sharing dude.

Nice vertical!

x270 work! thanks

Why did you move away from the foil pipe mag loop if it was better

I have old Ubuntu on orange pi lite. Can I install this bbs on it, too? Then I just connect a Heltec or waveshare+pi pico board via USB, with meshtastic on it, and it should work?

Maybe the software "Artemis V4" from Aresvalley will help you to identify the signal.

This was a great three-part analysis. I have one of those popular and "MLA-30+ (Plus)" active magnetic loop receiving antennas. It comes with a 10 meter-long cable permanently fixed inside the potted circuit box. Now after seeing this third part, I'm wondering how much the cabling influences the MLA-30+'s receiving qualities. Maybe that antenna is an idea for your video backlog; I'd be great to see you give it a thorough review.

17:57 maybe plus-minus mistake? (assuming the "tinySA Ultra" shows correct values): with the receiving "tinySA Ultra" showing 10.1 dBm, and cable attenuation at 1 dBm, the sending side provides 11.1 dBm; but the sending "tinySA" is configured to send at 9.0 dBm. So it seems the "tinySA" is actually sending with more energy than what is configured.

5:10 besides the signal-generating NanoVNA-F v2, the signal-receiving SDRplay RSPdx could also contribute to the frequency measurement being off by what is specified on the sending side.

also running on a raspberry pi using raspberry pi linux

running well on linux mint 21.3 thankyou so much for this

Great video, will install it this week on a rpi. Question, do you need to install a particular version of Meshtestic on the Heltec module?
