At the looks of it, the speed is about one character per second. The standard word 'Paris' can be sent in 6 seconds (including a space). So, it's about 10 words per minute. Not bad!
JS8 is not just for HF. The weak signal detection can allow for greater than line of sight propagation in VHF and UHF, typically via knife edge refraction over mountaintops or hills. The range isn't as good as HF but it generally provides decent regional communications. I just received some cables today and a USB audio interface that I'm hoping to use to make a simple low-cost interface cable between my PC and a handheld Yaesu VHF transceiver so I can start experimenting.
@@waylonk2453 - JS8 doesn't work well with FM but does work well with SSB. Many multi-band radios allow SSB for VHF. I wish there was a jumbo version of a 2m handy talkie that outputs 10-20 watts with SSB but that's a niche market. I think it's a chicken and egg thing. If it existed, there would be enough demand to make it a successful product, but it won't exist until the manufacturers see a demand for it.
You know, this actually looks interesting! I never even wanted to try FT8 because it was so impersonal and boring to me, far worse than a 59 QSL type contact. Thanks for the video Peter es 73!
I would love to be using JS8Call, future op here as soon as I get my HF radio. Going to happen soon. Is there specific frequencies that are used for calling CQ?
vk3ye on that note... most of the time JS8 call is on 7.075 Mhz. However, is recent months JS8 has been cropping up all over, and sometimes right in the middle of CW bands with what seems like no regard to good Operator standards. One guess is that JS8 users are not checking to see of the frequency is clear before sending. But that is only a guess. This topic has been a discussion at the SKCC for some time now. Personally, I don’t use JS8, but stick with Morse Code instead. I have personally seen JS8 calls on multiple areas of the 40m band. Any thoughts on this?
@@michaelsharp8229 It's a fairly new mode with (I'm guessing) inexperienced users. Hopefully it will settle down. What might be CW bands in the US are not always CW segments elsewhere.
If this mode is so efficient, why is the nightmare on 7.075 ALWAYS S9+20db? Digital modes are the most boring modes in amateur radio... but if they can't copy CW and are afraid of a mic - what are they to do? They don't check if a freq is in use because they just don't care. They're 'laying claim' to 'new' freqs like 7.060 - a global QRP calling freq. I wish I had a 2.5 KW amp so i could use digital on 7.075. 73 OM
@@michaelsharp8229 I would bet you are hearing FT8 rather than JS8. There aren't currently a ton of JS8 users and we all tend to stay on the freq provided in the program. 73 de KF7VUT
Yes it is. I believe it allows for you to have a 2sec error. The program also has a way manually time sync a signal built into it. It's great for qrp/p work. de KF7VUT
I've played around with all these digital modes and I just don't see the attraction. At all. I realize why they exist but they aren't enough to begin to hold my interest, they're like watching paint dry. I'll wait for more sunspots.

Thanks Peter. Happy to answer any questions y'all might have.

Now there's a thought--JS8 on VHF! I hope you've had success with it since this comment

Now if we could just get some of those Antarctic operators from the VK to get on the air with JS8. Those would be great people to talk to.

Exciting stuff Peter! I'm thinking that it might be a bit of a challenge getting this mobile (and probably a little costly).
Thanks!
Very good overview. Thanks Pete.
You need to be on the same frequency offset to chat?
No
Hi mate, what frequencies are we allowed to use this on in Australia?
See ACMA website for allowed frequencies for you ham licence category.
@@vk3ye thanks. Just passed my adv. Just learning the ins and outs

Just use the frequencies that are listed in the software and pick a spot within them that's free.

Great review. Is time sync required for JS8 like it is for FT8?
Yes it is. I believe it allows for you to have a 2sec error. The program also has a way manually time sync a signal built into it. It's great for qrp/p work. de KF7VUT

Not yet, but keep an eye out for future regulation changes.
