Is there a station that you really want to discover where they are transmitting from? kiwisdr.com/ has a solution. By using multiple online SDR receivers in tandom you can triangulate the position of radios stations almost anywhere in the world without having to use any equipment. Broadcast stations, number stations, even other hams.

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!

@SteveTheDocBenfield 2 года назад

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

Hi Josh Great video, nice explanation of DF. Chud M1PUP QTH London

@NA12495 2 года назад

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.

@SwampFoxOutdoors 4 года назад

very very cool. Would love a video on hunting down the jammers on winlink

@TLSO 2 года назад

Fantastic, thanks. Also good for those wanting to listen to Short Wave

@humaxf1 4 года назад

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.

@HamRadioCrashCourse 4 года назад

It’s pretty cool stuff.

@TheDukie54 4 года назад

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.

@bobgerzoff5072 4 года назад

Lots of fun just to listen around the kiwisdr's. Probably could use a video on that.

@1958johndeere620 4 года назад

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.

@HamRadioCrashCourse 4 года назад

Indeed very cool application of this technology.

@MatthiasLenardt 3 года назад

@ciscoscorner7147 3 года назад

Are there other methods to triangulate the location of the many different aspects of communications in real time, to include digital comms and RF?

@bruceblosser384 2 года назад

@EveryUserName 4 года назад

@MrMeasureTwice 4 года назад

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...

@Mach7RadioIntercepts 3 года назад

Yes VHF TDOA is pretty slick. Aircraft trackers seem to do well with this technique, using "MLAT" to describe this geolocation method.

@stewartrv 4 года назад

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...

@richardsternal3026 3 года назад

where is the satellite view on kiwi tdoa map, or are you using world map or something

@paulwatterson5992 4 года назад

I have a Baeofang but do not have my license yet. Are there frequencies on this radio that I can use without a license?

@HamRadioCrashCourse 4 года назад

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.

@applejacks971 4 года назад

You can monitor/listen without being licensed, but you can't transmit or talk.

@glevideo 4 года назад

How long of a sample does it need? Many times jammers make short transmissions.

@HamRadioCrashCourse 4 года назад

About a minute. Try it out.

@RosssRoyce Год назад

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!!

@HamRadioCrashCourse Год назад

Nope they’re independent.

@jorgezuni2818 2 года назад

How can someone from; A Different country find stations to; Los Angeles,ca . Is there a configuration to acces GPS .

@AG7SM 4 года назад

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.

@HamRadioCrashCourse 4 года назад

Sure. I mentioned that on the video. 👍

@AG7SM 4 года назад

@@HamRadioCrashCourse Look at that. I'm that guy.

@HamRadioCrashCourse 4 года назад

No worries. You’re likely right!

@scottpyles1 4 года назад

Consider that it found the antenna- not the building per se

@Mach7RadioIntercepts 3 года назад

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.

@kyrenegade858 4 года назад

But the antenna and transmitter could be remote from the office location.... so maybe it is correct...

@IraQNid 4 года назад

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.

@HamRadioCrashCourse 4 года назад

No, not really. Just df the repeater Input frequency.
