- Getting your messages through with ham radio data modes for survival and preparedness.
Hello Operators
In this episode of OH8STN Ham Radio, we take a look at circumventing ham radio jamming using digital mode communications. A couple of weeks ago, Alex W7HU posted a video showing what he says was jamming by the Cuban government, of the ham radio 40 meters band. After watching his video and understanding the type of communications needed to get news and information in and out of the country, I put this tutorial together. This vidro explains how ham radio digital modes can be used to circumvent jamming and interference on the amateur radio bands.

No more political than a printing press.
@@timferguson2682 Agreed 🙏
Julian, it is a more procedual video and has nothing to do with politics. A while ago, RRI has published a presentation with similar content, how to secure operate in the aftermath of a disaster.
Keep on your way.

Nothing political about wanting to get your message out and someone showing you how
This basic outline of how to send out information isn't just important when people are looking for you, but also a great reminder that digital communications can relay more information in a shorter amount of time. When a person has to vacate an area due to fires/earthquakes/volcanic events/whatever seconds count, and being able to transmit a message to friends and family about your situation is critical. Thanks for reminding us of this fact.
And thank you Michael for this comment. Sometimes it's simply not enough to post a tutorial, the additional context is often critical thanks for the kindness and the reminder. It's very much appreciated.

Fascinating. I actually never got into digital comms like this. I tried it a time or two, but I t just never really interested me much. Now I see a much more practical application and will start looking at these options more closely. I’m not sure where to start, but start I shall. Thanks for the motivation, Julian. Thanks very much!

Timely and on point, Julian.
Thank you Dave
4m15s but the difficulty is always on the receivers side. If the operator receiving can't copy 100%, the message has to be sent again in part or in its entirety.
Awesome work. Love your pragmatic approach to teaching.
Agreed. This is the key benefit of some data modes. Even with resends, analog is never going to be faster than data when sending something substantial.
Thanks for the comment and kindness. It's fuel for the fire.

You make excellent points. There is far more that needs to be discussed when it comes to dealing with sophisticated "actors" wishing to disrupt communications, particularly if they are willing to resort to extreme and possibly illegal methods.
Always appreciate your feedback and insight.

Thanks for the video Julian! Political? Jamming may not always be intentional - a power generator in the neighborhood, city noise, bands are overloaded, noise is high on the band you want to use etc. - all principals described will help you also to overcome this as well. Vy 73, Uli dd5uk

This is good for military and emergency situations. I have worked in military, without modern technology, and now emergency conditions. Being able to get information out with guaranteed reception is the prime need.

Fantastic video, looks like RadioPrepper is the BustaRhymes of CW now! Hope that nickname sticks. Thank you for all your work on this.
NVIS antenna system is something you need to learn as well
I’d say it’s worth setting up a permanent NVIS ant. either at your QTH or in the field somewhere accessible. I’ve got one on the tallest hill in town, thanks to my grandparents and their address. 5-9 anywhere in the county.
Wire is cheap, insulators are everywhere, make a few antennas and strew them around the countryside.
We love what you do. Thanks for this video. Its a light during dark times.
Appreciated that more than most know. It is all about giving back to the community.
73
Julian oh8stn
Good video!
In addition to using QRP, a NVIS set up will make triangulation more difficult. The expected 300-mile radius would be effective in the case of Cuba as they are but 90 miles from Florida.
Thank you and agreed. NVIS has been a tough sale to uninitiated. Perhaps we need to revisit this topic.

I'm a CW nut, primarily because I'm an ultra-portable operator who needs to shave ounces off my pack weight to be as light as possible, and CW-only rigs will always offer the lightest possible configuration. But while CW has some advantages against jamming due to its small bandwidth, in a critical situation where jamming is present I would absolutely defer to JS8Call and Winlink. Not only are they going to be faster, but their algos are mathematically designed to account for noise (error correction, signal recognition, etc.). Great video and excellent points raised.
spot on my friend, great job, and i have a lot to learn
You do a beautiful job on your vids. Very clear, concise, professional and well done.

Thanks for this. The topic was a good segue for a comparison of data communications vs voice in regards to jamming.
Excellent video!
This was a great video
I got an IC-705 and primarily been using it on HF (SSB), 2m SSB and FM simplex along with local repeaters, as well as D-Star. I purchased a new laptop a couple months ago and been wanting to get the most capabilities out of the radio. Been trying to learn how to use FT8, but that's still a working progress.
What I got from this video is that adversaries, 3rd party actors and band conditions isn't always on the amateur radio operator's side. One must use whatever mode and/mode to get out, especially in an emergency situation.
73, W4ISB
Everything is against the operator, including the massive amount of noise pollution from junk power supplies used by phones, etc.
Outstanding, never used VARA as I use a P7400 - thanks
Superb video

Julian oh8stn
Great video, Julian. Conceptually, I've been in favor of JS8 because it can be run end-to-end 100% off-grid, and because of its weak signal capability. But it' takes much longer to send a message via JS8 than it does via Winlink. Also, if I remember correctly (it's been over a year since I used JS8), all of the stations in a JS8 network need to hang out for a long time on a fixed slice of the selected band. And, as long as the internet is available, Winlink provides the hit-and-run advantage you discuss here. Would it be possible for you to do a similar video on the advantages and disadvantages of JS8 in a jamming scenario? Maybe you've already done or plan to do this.
My suspicion is that in certain scenarios, the ham bands might be jammed in their entirety. Hopefully, I overestimate the feasibility of doing this.
Excellent feedback and questions. JS8 offers different advantages than winlink, but it's just as valuable as a tool. Definitely plan on covering it 👍

I've been on the other side of this. When I was in the US Army I was a SigInt interceptor (East German). Back then (1990) with the push of a button I could get the grid coordinates for a transmitter's location in less than a minute down to (really close...can't say how close...it's secret). We'd go on training exercises and jam with music. We called ourselves, KPIG, "K-Pig Radio - the VOICE of Hohenfels!" (training area we used to go to waaaaay too much).
I could be incorrect, but triangulation is different when tracking a vertically polarized antenna VS a a horizontal one.
More study is required, but there is a difference in traceability.
Nice to hear from you Richard 😂👍
If the signal can be picked up by a receiving station then a Line of Bearing (LOB) can be determined. Two LOBs gives you a "cut", accurate to kilometer or so. Three LOBs gives you a "fix". That's accurate enough to drop steel on you. I too may be incorrect; but polarization doesn't factor into it. If the receiving station(s) can hear you; they've got you.
@@RESlusher Ex-LRS here. Agreed. We had to keep our transmissions very brief to prevent giving up our hide site.
Good stuff!

Excellent video in every respect. Sat coms might work in some situations too. 73's. AJ6RE
Thanks and agreed. Sat comms is always a nice fallback method. Unfortunately it also has an off switch which the end user cant control. Definately worthwhile if off grid with a broken leg, ankle, ... and need to call for help. I really wish Starlink were more portable.
you are so goddamn awesome!!
No words 🙏👍
Thanks for this video. I just got into winlknk. I hear the sound on 40 all the time. I like to know why psk is not used.
PSK is WAAAAAAAY slower
Winlink is an asynchronous mode. That means you don't have to be on the radio at the same time to send or receive the messages. Like Lee said, PSK is also very much slower. It is good in a keyboard to keyboard chat in real time, but can't do what winlink does with email, or asynchronous messaging.

This sure seems even more important than it did a year ago. 14 yr Daughter is now a general, 11-year-old daughter is a technician now for 2 weeks, taking General early next week.
14yr and I are learning and practicing CW, but we are using digital Coms as well. No doubt digital is way faster, but CW is more fun for now, while I can still get coffee, and at least fewer people are shooting at me. LOL
I think they can both find a place in the bag of tricks. :)
As always Love the vids!
Agreed. I'm here having a sleepless night, pondering what yesterdays results mean for global security.
@@OH8STN My daughters shot idpa, on the weekend, learned Linux more, this evening learned HVAC vaccum evacuation techniques.
HF CW practice, followed by more Rig Stick Pro tuning videos, etc.
Their education is far wider than most children. Experience in a lot off different things. We're on our own. Entitlements end when currencies do.
Julian, I’m intrigued by your videos and new to jam radio. I’m wanting to get my equipment setup for portable data and off grid like you have. Money isn’t really and object but I’m technologically inept. Any suggestions?
The starting point is always figuring out what you want ham radio to do for you. When you figure that out, it is pretty easy to get started, with all the tutorials on TH-cam. Ask lots of questions, and do your gear research. Whatever gear you decide should support your primary objective in ham radio.
I hope this helps.

Julian oh8stn
With winlink can you save messages in draft? Then share the login details with who you want. Easier to protect your identity that way. And pressumably it never hits the internet as such?
Perhaps it would be better to focus on the"radio only" or Peer-to-peer sides of winlink, rather than focusing on the cloud side of things. Always avoid the infrastructure when you can.

I don't have that type of video yet but I will. It's not an elite hobby, just an expensive one. Kind of like shooting, it can be pretty expensive if you don't know how to find the good deals.

Thanks for this! It's truly a concern we should all have and now we have tools to handle it. I do have a question. What is the likelihood that someone could take control of any radio that has the ability to be controlled remotely, such as the IC-705?
Not very likely. There are so many pieces of the puzzle that we need to have, before they could control the radio. Firstly they need to get into the network. Then they need to remote access username and password. Even then, the radio denies old connections which aren't explicitly allowed. The only way someone could control the radio, and see if you gave them access.
Thank you for answering! I've been thinking about this being a potential problem, but wasn't sure how to work it out.
Julian - you are the best Ham! Thank you. We discussed how great your teachings are at the local Ham club this week. One question - could a larger HF rig like a Yaesu FT10 be configured to use power more slowly like an Icom 705? If your strategy is "bug in", how would you handle this if you had to keep your shack rig going as long as possible?
Thanks for the kindness.
Unfortunately, no. None of the QRO rigs available today can be "turned down" to a less current hungry state. Even on RX, the consumption is too high. On TX, the power modules are designed for cheap mass production, rather than the highest efficiency. This is the reason for using efficient QRP rigs with an efficient amplifier. It's expensive but efficient. My home station is a 705 with pa500e amp. Total rx current under 300ma. Total tx current at 100w, 10 amps. This is compared to my ft891, which used 1.2 amps rx, and ~20 amps tx at 100w.
Great question, not good answers.
