Only those possessing a current Amateur Radio license are permitted to post in this thread. Pirates and Makers illegally using shit they bought from Alibaba may only listen-in, in the hope they catch the motivation to infect themselves with the Ham Radio meme.

Just made this bad boy j-pole antenna, and now using it for a 1200 baud TCP radio link. Unlike previous j-poles I've made, its radiation pattern is actually what it's supposed to be (i.e: pointing it at the repeater actually gets the strongest signal.) The marine varnish trick to waterproof it is brilliant, too.

ffs ARRL, don't you also start swallowing the Radio is "Alt Tech" propaganda.

Ha, reminds me of about a fortnight ago when there was someone trying to sell Baofengs 'cheap CB radios!!' on the local UHF repeater's output frequency. I only noticed because I was fiddling around with the FT817 and didn't have the CTCSS squelch set up.

If you are not making a mesh network to replace the Internetz in case of "ooops you got banned because you forgot to praise X today", you are doing it wrong.

Ham people can be super annoying. They praise communicating with morse and in many cases they only care about those antennas without setting up a magnificent digital network. Come on, it's the god damn digital age. Ham radios are cool but come on, step further. Boomers only jerk off to their call signs and calling another boomer far away while the modern cool kids can even talk via microwave + satellite.

I think Burgers have some 300 baud bitrate limit on the HF/<30MHz bands, which the rest of the world doesn't have, but this is VHF, where 1200 and 9600 are acceptable, and UHF gives about two orders of magnitude above that, and SHF/Microwave/2.4GHz and above is basically unlimited.

I've made one of these with copper pipe and expensive connectors, the design shown here looks easier and every bit as functional. I connect it to a baofeng and get pretty good legs. Almost necessary to use an antenna like this with a baofeng because the stock antenna is no gud unless you are low power for tactical reasons. A ham can show you how to tune it. This length is typical for 144mhz but a swr meter will help you tune it for optimal performance. You want the lengths to be perfect.

J-pole will work with any radio. Just saying, don't throw the rubber duck away after you get that Nagoya 771. Intra patrol comms has its place. This is why I tell people to get a license or at least study the theory. You never know what you will need to know or fabricate.

The reason to take the test is 90% to internalize the theory, but also about 10% is about how not to use your radio so you broadcast over a pilot's frequency or turn off some guy's pacemaker. What's in it for you? Knowing the theory and having the basic credential that is respected by the guys who can take you quickly to the next level of tactical and long range communications, antenna building, equipment that you can make or buy or somewhere in the middle. HAM radio is the big guys helping the little guys become big guys. There is no other community like it really. It's the test, you're already proving you're smart by passing the first test but also practicing the etiquette and that includes helping our own. Don't waste time. Get the license, meet the guys, make and/or buy the gear and get plugged in. This is a new era of digital comms over analog. Get in with a group and let them get you up to speed.

Holy shit cringe. Where did you get all that bullshit, the AARL website?

You can freely use your grandpa's rusty rifle and accidentally pierce somebody's heart with a bullet if you're not careful. But you can't use a 5 W radio without a loicense because reasons.

An HF radio won't bring down an airliner. HF comms are inherently unreliable in the first place, and all the ILS and VOR navigation stuff works on VHF and up. The muh aviation excuse might apply to some extent to broadcast FM pirates with shitty diy equipment (that hams are allowed to use mind you), not to commercial ham radio gear. A Yaesu HT won't suddenly come up with spurious emissions in the aviation band just because of who presses the button. How many hams have ever hooked up a spectrum analyzer to their radio to monitor the purity of their signals? I bet less than 1%.

I know the ham radio community. And there are no "big guys". It's all a bunch of old farts circlejerking about how good their 2000 dollar rig audio is or how special they are because they built an antenna for 40m once.

>>1086436

>look at me mom, I took a test with memorized answers from a phone app and looked at a radiation pattern once, I'm special now, I'm a ham radio engineer!!!

I respect hams who build their own radios or know how to use a smith chart or accept they know nothing about electronics and are in it just to talk with other old fags, but you're exactly the kind of midwit that makes it worth it NOT to have a ham radio license.

>>1086424

Or I could not do radio and use the fucking phone or the Internet.

A car is useful and it's not just a circlejerk for people to feel smug about it. If shit hits the fan ham radio is going to be banned anyway like it was in WW2 and you're gonna get raided by the feds if you transmit. Not that it would be useful in the first place to talk with some random old fag in the other side of the country.

And you're ultra fucking retarded if you think an overdriven HF amp can have spurious emissions in the UHF band.

If it wasn't for hamfags we could have a functional mesh network spanning the whole world that was more use than talking to Bobby the boomer down the road

While phone BBS had Fidonet, MUD games, random textfiles, ASCII art etc. hams had shitty BBS where the only function was leaving boring weather reports for other ham boomers.

Same with modern shit like QO-100. What can you do on it? Talk with some german cucks on SSB and watch some shitty digital TV channel? Imagine if that spectrum was subdivided in 500hz channels and used to host BBSs, store and forward messages, email, text based web browsing etc. Or HF. FT-8 is so boring only a ham could've came up with it.

No wonder the only entertaining activity hams have is jamming each other

Don't forget the APRS digipeaters on VHF. Where is it available, even if only relatively sparse, the potential is there for a mesh network with a significant range, or at least until it hits an iGate.

A few APRS iGates on HF, too. (JS8Call is just too slow and capacity issues..)

APRS has no routing capabilities. Yes there is iGates but at that point you might just as well connect to a cell tower, which is probably most likely to be available anyway in most countries.

JS8 is not that slow in the faster settings. Remember that the higher the data rate the stronger signal you need to maintain a connection. With these slow modes a 100w radio can reliably reach thousands of km, with faster modes not so much.

It also has a feature to redirecting messages to the APRS network but I don't know the details.
