If you are unlicensed or don't have an HF radio, this is a great way to start building familiarity with the software that's needed, without having to buy anything. The caveat is that this method requires a steady internet connection, so it's not great for off grid use.

always a good day when a new S2 video drops
VERY. i love it!
🇺🇲
I agree... I keep this channel on my alerts.
MORE UPLOADS! Plz, we need ur insight. We can't rely on news anymore, and instructional vids like this are invaluable. Also, some war kitchen would be cool, I was enjoying those.
For those in the comments, running JS8 call with an RTL-SDR is essentially the exact same process. The difference is that you set up the RTL-SDR to run in SDR++, listen to the frequency you want in USB (Upper Side Band) mode, run the virtual audio cable to JS8call, and it should work exactly the same way.
Don’t you need to set the filter to Q mode or somthing like that?
Yes@@Blastogy Q branch is the correct mode to sample HF frequencies. I was fairly vague in my explanation but if you want something more specific there's a fair number of RTL-SDR HF tutorials online.
Would a DIY dipole work for this? Just make it as long as possible?
@@BobBob-il2ku worked for me. 2x wires flung up into a tree.
@@BobBob-il2ku Try to optimize it to ~10-15% of your wavelength. E.G. for 40 m it should be about 4-6m, or 12-18 ft
God bless S-2 underground. Fight in the shade.
You could set this up to text your team securely. You can say a lot more in three seconds over text rather than communicating by talking or keying the mic for long periods to talk. The longer you key the mic the faster you will be located.
How is it a secure setup?
As a Patron, this video is incredibly well timed... Thank you!
As always, anything from S2 is greatly appreciated. Communication is going to make it or break it for us at some point… however the analysis or brief of events taking place across the United States that is never reported is vital now as well.. there have been so many things recently I would really like to hear from the team about.. of all the channels out there S2 is nearest and dearest to me and most similar to my own thought processes in many ways .. I know that you are very busy.. it would just be really helpful to get your take on the current position of things..
This is timely. I've made it my goal to get my general ticket before the end of the year.
All the BEST of luck to ya mate!
Enjoy! 😁👍🤙
Once you get your ticket, play with 10m with SOTA and POTA and go for the general as well.

Never a bad video. Makes me smile with every upload. Can't wait for the next!
This is perfect! This is exactly what I want to learn and have a deep understanding of. Thanks for the video! 🤘
Fantastic quality as always! Thank you for the info!
S2 fighting the fight that matters!
Wake up babe, new S2 Underground just dropped
I'm reading between the lines and paying attention. Hopefully more are...
Yep.
[reconsiders]
No... no no... I know nothink!
looking forward to learning how to receive and decode JS8Call with an RTL-SDR.
It’s the same process like he showed in the video. Have the RTLsdr audio go through the same VBcable program and enter js8call
I'm surprised they don't have a third option for time syncing, using the various national atomic clock radio transmissions. My watch does this. It's very convenient to know precisely what time it is for manually syncing things. It's more accurate than my cellphone. Software, especially radio software that has the ability to receive these transmissions, should be able to do this automatically as an option.
Had it installed waiting for my licence but didn’t know this! Good to know!
Great info. This is great for not just non hams but newer hams as well.
New S2 video. It's a special day.
This is another great episode. Thanks
Great tutorial and thanks for mentioning time synch
Much love muh dude! Thank you for your good work!!
9:55 I live right close to the Corrine, Utah SDR towers. I'm learning as much as I can and I'm connected to the local repeaters but I need someone to talk to and walkthrough with.
Great Video S2U,
Fight in the Shade.
Oh man! Something free to play with Love it!
God bless the underground.
Going to playing with this for sure.
When are the 2nd part of earlier videos coming out? Excited to watch them :)
Thank you, got my ham because of your videos
I got it working on Linux using Pulse Audio for the virtual audio cable.
The other reason you input your callsign into the program is that the program automatically feeds the reverse beacon network and others to tell the ham community where they have been heard.
Just in time for my sdr antennas to get here, fuck yeah
Great video!
Sounds like a great backup and redundancy for when the interwebs go down
Good for anything where cell/internet isn't reliable. I'm going to consider using this for backpacking and backcountry skiing.
Is it just me, or is this a direct response to the recent inreach video by Trex. Lol. Good video.
Can you send multiple packets of JS8Call for longer messages?
You can send multiple 15 second messages - I have sent 3 or 4 minutes worth in the past - full paragraph
Thank you 😊
very interesting !!!! 😮
Can’t wait for the SDR dongle + antenna version of this video
Will it be a DIY dipole to save $?
Top notch!
Get a very accurate real time clock RTC that’s temperature compensated and comes with a supercpacitor or a battery. Might be expensive but you won’t need GPS much, one sync would be good for a year or so.
If you created your own key that only you and your friends know like if you both had the board game battle ship and spelled letters it could be a good basic encryption
Have you thought about CW at all? Learning about that Admiral in WW2 that blinked Torture has stuck with me long enough to start learning.
CW is still the best way to get a message through under rough to just borderline impossible conditions, HOWEVER there's NO, ZERO SECURITY on the signals!
In a SHTF situation the ONLY security your messages will have is the code book that you and all your team members ALREADY have, and don't forget, even a descent Intel 386 can run software that'll be able to crack the average cypher, so don't forget to layer it, it's NOT perfect (no cypher IS) but it'll piss the red team off enough to maybe make them think twice about the one IMPORTANT message, especially if all the others are routine house keeping messages.
L8R 🥴
@@joemcmanus79 CW used to be the best for poor conditions but this isn’t true anymore. JS8CALL and similar modes are roughly 6 times more energy efficient and decode at much lower SNR values. Got to keep up with the times…
@@hardwired3640 Good day to ya, I want to make this PERFECTLY clear, I was not in any way, shape or form denigrating JS8CALL or ANY of the other digital modes in any way, I was speaking of an overall type of situation.
In a SHTF situation, (a worse case scenario) a person might NOT have access to a desktop, a laptop, notepad, or even a Raspberry Pi, to run the decoding software on, he/she might not have access to GPS or a stable / accurate time hack, or hell, he/she might barely have a radio to RX with due to the existing circumstances what ever they may be.
When you get down to it, one should always prepare for the worse possible conditions, and prepare to work within those conditions and constraints and go from there.
When the SHTF, old school might JUST save a life or two.
73, de WB2ZDB
More please 🙏
Does this mean we are finally getting the Intel briefs by HF??
can you use a timing offset on the time sync in a sudo encryption between radio's ? as long as all are on the same time.
It's time for some s2 analytical therapy!
Does this work on a Apple Laptop? Asking before I attempt it as I’m old and well ya know 🤦♀️
You said you're going to make a follow-on video showing how to use it with an SDR, right? I'm trying to figure out the best way to set up an alternate way to get messages out to teammates if the internet goes down, so this obviously isn't quite useful for that application just based on what you've covered in this vid. Still very useful for testing, though!
Feed the js8call program with audio from an RTLsdr so you aren’t dependent on the internet. He’s showing people how to do this for $0 free and that’s why he didn’t use an RTLsdr even though that’s the ultimate goal
He mentioned RTL-SDR, which doesn't transmit. If you need to get messages out on HF you'll need an hf-transceiver, one of the most capable for the price at this point in time is the xiegu g90
@@user-si6ex2lf1l while the g90 might be a fine voice for people, keep in mind the total cost of ownership. Most g90 openers are new the the hobby, seriourls users will upgrade to other setups quickly. Just sending this for newbies who might read. You’ll be Monday ahead to skip to Icom or Yaesu range
@@user-si6ex2lf1l Yeah, one of the team members has a Yaesu FT-991a for transmitting the messages, but no one on the team can receive them yet!
Does time syncing work with a GPS with no PPS signal, but rather RX/TX lines?
I followed the steps but never found a heart beat. hopefully i can test out the next Call to see if its working.
Downloading this video just incase lol
Doen't websdr introduce delay? I think when using web as a source you can skip btk sync entirely and always recalibrate you receiver to match time slots of particular sdr feed.
Will this work on a phone or only on an actual computer
having trouble getting vb audio output to show up for the input on js8 call please help
What if every station on your net purposefully changed their system timesync to an incorrect time?
Would that enable some type of security via obscurity?
It’s easier to just find your own frequency somewhere other than the standard frequencies
What a great video. would really like to see a follow on to show step thru step on connecting to your ICOM IC-705 in th future.
Do you think it would be possible to set up a WARC band JS8Call/Emergency news outlet in case of disasters Since radios like the UV-K5 are becoming more popular and with Chevron deference being struck down people can now use them with a simple GMRS license.
Can someone explain to me how you are supposed to hear on this. Since the system audio is fed through the virtual cable, even if the JS8 call option says output on computer speakers it won't generate noise because the computer is sending it to the audio cable. It seems like it's a little bit of a circular output situation. If anyone can help, that'd be great
I've got a panasonic toughbook, but unfortunately only has one usb port. To sync clock via gps, could I plug the usb gps in, and sync in bkt time sync, and then unplug the gps, and plug my digirig mobile in? Great tutorial by the way! I hope you do more like this for the common user.
Is a USB hub an option?
Hmmm...I did not factor in Linux Mint.
time sync and virtual audio cables are a no go.
JS8call seems to work fine...but doesn't actually connect to anything.
What are you using for a personal HF rig? I've been tempted to pick up a 991A.
The 991a is not good. IC-7300 for home station and IC-705 for portable work
@@hardwired3640 What's your reasoning? IC7300 isn't UHF/VHF.
@@Munky332 the 991a performs poorly with digital modes, not user friendly, has com port issues, waterfall scope isn’t real-time. Best to keep hf separated from vhf/uhf. Typically you need to be monitoring vhf while using hf. Don’t put all your eggs in one basket. The 7300 won’t disappoint you, I promise. The 705 is great for portable HF. I don’t count the vhf/uhf capabilities for anything other than another backup to the primary vhf/uhf radio(s)
@@hardwired3640 I need a full time all-band all-mode radio, the IC7300 doesn't fill that for the price it sits, that's all I'm going to say. Don't get me wrong, I want one, but not being all-band all-mode is a deal breaker for me.
Can you intentionally offset the time on both ends where only the two can decode it???
Noob question, is the reason we have a websdr site open the same time as JS8call to hear the traffic? I cannot hear anything from JS8call alone. I have the VB audio virtual cable enabled. Thanks.
Is there an equivalent of BktTimeSync for mac?
How much data does listening use? I’m on a metered network.
Well what are the signals?
Do they have a GMRS option?
Can I transmit using that SDR? I do have my General License.
Please help. I followed the instructions in this video but when i boot up js8 it says it can't open the audio device. I have been troubleshooting for hours and have found nothing. I've uninstalled and reinstalled VB audio cable. Also, I've messed around with the settings on js8call, and nothing works. even the waterfall is blank with no signal or input at all. can you tell me exactly what settings you used, and any other advice you could give? Thanks!
I don't understand why it syncs your system time instead of allowing you to chose if it will sync its internal clock that counts up with system "boot" clock. That would be nice and will not require from you to tinker with OS settings.
Biggest issue is that the system clock is "kept alive" by your CMOS battery. If it goes dead (which they do more often than you'd think) you would have to manually sync time anyways. Until you replace the CMOS you will have to re-sync it every time. Also, I'm sure timezones play a role in it all too.
My timing window is 10 seconds and not 15. How would 1 change that? Also, thanks for the information!
I found it. It was under the 'Mode' tab.
Hi would you be able to use a sdr and then use without a internet connection? In africa the governments have been known to cut all internet
I couldn't imagine living in a country that turns off an entire ISP. One could call it an Internet apartheid? 😅
@@Fluffy2BuffyWhen a country is small population wise its easy to do... Swaziland/Eswatini did and some of the other ones up north. We have 2 sea cables and some fiber to South Africa.. and some satellite links. Fact of the matter is, its possible. Likeliness is a matter of circumstance .. Almost like privacy
hey we got atleast 5-6 years untill its total shit over here. We still have mostly privatized grid, ISP on the other hand.. We invented 5th generation warfare.. .. that war was lost in the Bush era..@user-zm7qz5fq2d
Yes
This is way over my head, but wouldnt all this be useless in a situation where our power grid goes down?
I would love to see some updates in your intel reports on the power grid failures since covid and perhaps since 2016
No worse than the radio itself. You just have to keep the battery charged using some kind of power source and any repeaters you’re using need to stay up as well. I guess the way to think about this is that the more you know, the more options you have to handle any failure in parts of the system along the way. Obviously there are totally catastrophic scenarios that you couldn’t overcome but those are unlikely.
New video!
Are we supposed to actually hear anything or is it only text? I followed the video and see exactly what was on the video but see no text and hear nothing. It keeps asking me to use my grid locator but I don’t have that
All that I get is a message which states "Audio not supported on this device 😮.

The first mistake is running the 32 bit version of windows 10. 😅. Driver support in 2023 for hardware either a 32 bit is is scarce.. might as well move to a Linux distro dude.

Make sure to disable pskreporter logging!
does anyone know if JS8Call can take input from a UV5R and decode incoming digital transmissions?
The uv5r is totally the wrong tool for the job. If you’re determined to stick with the uv5r than APRS or packet radio is the mode you’re looking for. JS8CALL is for SSB radios and is much better.
thanks for the reply, im new to the radio world, so i dont really understand much of what you just said lol. im interested in how to set up a local police scanner on the cheap, just found a video on how to do it with an SDR. im seeing now that the uv5r is definitely not the right tool for the job. @@hardwired3640
@@joecactus91 if the public service channel is analog the UV5R will work. If they’re P25 and not encrypted you can use an RTLSDR in conjunction with DSD+ program to listen.

Does the government have access to see/hear the messages people are sending?

👍👍
Not sure how js8call is supposed to be functional without the internet in terms of shtf.
When it’s connected to an HF radio…
The whole point of js8call is that it works without the internet… not sure what you mean
This is a way to learn JS8Call, and if you add an SDR dongle to your computer you'll be able to get the signal from the airways without the internet. Once you're equipped with an armateur radio, that will provide both send and receive capabilities. At least that's my understanding.
😊
Legit
With all due respect, I implore y’all to invest in analog everything
More heavy stuff.
BTW, FYI 7.078 MHz would be LSB (Lower Side Band) NOT USB as shown herein.
I mention this for all those who don't know .
Furthermore, 2,200m, 630m, 160m, 80/75m, 40m bands are ALL LSB, 20m bands and up are all USB.
