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.

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.

@Blastogy 10 месяцев назад

Don’t you need to set the filter to Q mode or somthing like that?

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.

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.

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.

@fliper975 10 месяцев назад

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.

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.
