Just ran across Kiwi SDR... using it like an SDR alongside a non-sdr transceiver makes it fun. You can even record your QSOs from the receiver you have selected. This is a fantastic tool. Thanks for the video Josh! 73
I'd love to be able to have conversations with you about this topic. Finding someone who knows anything about direction finding using TDoA at the unclassified level is pretty awesome. You obviously know a lot if you're doing direction finding. Good video!
Loving catching up on these shorter vids - discovered HRCC via Mike Glover (or vice versa possibly) in the past few months and planning to test for my Tech license soon.
Impressive. Tried in with a longwave transmitter in Ireland on 252khz. Located it 10Km west of the transmitter location. Not bad going considering the receivers available to triangulate with.
Hey, I just stumbled upon this while looking for something else :) I use Kiwi SDR with Catsync to my 7300. and never even seen it till now. Awesome thanks man as I only just got my Lic here in Australia. 73s VK5DOC
Watched your video about using DF to verify a station was jamming other Cuban stations. Which I had saved the link to the website that you used. Today I was studying for my Calc class. Tuned on the radio to take a brake. First thing I heard was a station making comments that people from a particular ethnic group needed to die. Then there was playing of Taps. This had to have been done intentionally. Wish people like that were located and reported to the FCC.
What a great system! Looks like it is all HF band, right? Would be cool if there was some VHF coverage - mostly to locate a repeater since some repeater locations are not shared openly. Just a thought...
One or two of those SDRs may have been in the skip zone of WWV, receiving only backscatter from several directions. Results are quite good if you use receivers getting the signal on one hop.
The deviation could be any thing that frigs with the time. Its all about exact to the millisecond difference to the comparing receivers. GPS works to 3 feet, but its time stamp is all controlled and its line of site rf ( from satellites ). Pretty cool system, really neat.
Thanks for your great video's. I am learning a lot from you. I have a question, I hope you may have some insight on. What is a good solar charger for a Baofeng UV5R, with extended battery? I'm building a radio network for a group of people up in the mountains. Thank you again.
Not really. Using the baofeng on the ham frequencies without a license is illegal. Using a baofeng on frs and gmrs frequencies is illegal since it’s not type accepted. See my video on transmitting on frs and gmrs for more Information.
I just described to you gentle just now I like everything you got to say bout radios you very knowledgeable and very educated in radios I got a few questions for you but I wanna send him a new email thank you very much God speed in God-bless
I don’t understand, if I choose one person’s SDR and move the tuner, do I move the tuner in his home? If we are two users moving his tuner frequency in two different ways simultaneously, would we create a conflict for the software? Thanks for this vid!!
could it be that you are getting bounces off of the mountains there, and that's confusing the position? Since they can't spin a beam around they are likely using the signal delay between the stations, and reflections could really mess with that. But I'm just speculating.
Cool idea that is easily defeated with repeaters that are fed broadcasts via cellular, satellite, or wired data from like a high speed Internet Service Provider. Considering the amount of money that goes into this hobby it is entirely plausible for folks to stream the pranks to remote locations so that if someone were to try to sniff out their location they'd be spinning their wheels.

keep more KiwiSDR videos coming on how to listen to different station's through the country both PC and phone Keep up the good work
This is really incredibly! ... oh yes, I'll want to be part of this community ... it's time to get my kiwisdr ;-)
Nice explanation of using the direction finding feature!

ABSOLUTELY BRILLIANT use this site all the time but never knew about this feature THANK YOU 😷👍

Yes VHF TDOA is pretty slick. Aircraft trackers seem to do well with this technique, using "MLAT" to describe this geolocation method.
very very cool.
Would love a video on hunting down the jammers on winlink

Indeed very cool application of this technology.

WWV transmitter is located north of Fort Collins (nearer to Wellington Colorado
I have a Baeofang but do not have my license yet. Are there frequencies on this radio that I can use without a license?
Not really. Using the baofeng on the ham frequencies without a license is illegal. Using a baofeng on frs and gmrs frequencies is illegal since it’s not type accepted. See my video on transmitting on frs and gmrs for more Information.
You can monitor/listen without being licensed, but you can't transmit or talk.

"Your favorite jammer on the 80m net that you listen to". Nice pun. Awesome video
Hey Josh, finally watched this video. Awesome tool and capability. You know of any similar system to do 2m and 70cm?
Wow! This is entirely new to me. I an going to have to try it. Thanks so much for sharing this! ♥
I don’t understand, if I choose one person’s SDR and move the tuner, do I move the tuner in his home? If we are two users moving his tuner frequency in two different ways simultaneously, would we create a conflict for the software? Thanks for this vid!!
Nope they’re independent.
Are there other methods to triangulate the location of the many different aspects of communications in real time, to include digital comms and RF?
Lots of fun just to listen around the kiwisdr's. Probably could use a video on that.
could it be that you are getting bounces off of the mountains there, and that's confusing the position? Since they can't spin a beam around they are likely using the signal delay between the stations, and reflections could really mess with that. But I'm just speculating.
Sure. I mentioned that on the video. 👍
@@HamRadioCrashCourse Look at that. I'm that guy.
No worries. You’re likely right!
How can someone from; A Different country find stations to; Los Angeles,ca . Is there a configuration to acces GPS .
where is the satellite view on kiwi tdoa map, or are you using world map or something
Very cool indeed, I don't think it works on VHF or UHF sadly as that would be cool to catch the phallus heads messing with repeaters...
love kiwi sdr.. i just subbed. thanks from k2yk
But the antenna and transmitter could be remote from the office location.... so maybe it is correct...
I came to comment this.
Hi mate. On Callum’s channel we are getting confirmation within a mile or less on signals. It is a very interesting tool and great fun. 👍
Hi Josh
Great video, nice explanation of DF.

Good info! Another weapon in the arsenal when out to find stations!
Thanks!
How long of a sample does it need? Many times jammers make short transmissions.
About a minute. Try it out.
I think "that mountain" is the Rocky Mountains. It's an entire wall of mountains.
Great video! I never knew this existed. Neat little tool.
Consider that it found the antenna- not the building per se
the map covers 80% of the list of stations, and I can't get it out from behind the map
Oh that is cool!
Why why can't you pick a green one? Now at the same time I ask this question I don't know what the hell you doing anyways.

No, not really. Just df the repeater Input frequency.
Seven threes? Oh boy.
Hey! You’re the winner! I was wondering who would be the first to complain about that. 🤣
@@HamRadioCrashCourse LOL. Just waiting for the OMs to start up!
I thought it was Seventy Trees?

Sextangulation. :)
