>not putting an icom 7300 in your car

Weak tbh

I've set up an old Icom 2m rig and a MFJ 1270C TNC at the shack to do APRS but can't see doing that with any of my mobile stuff. It took me a long time to decide to get a ham license because my shack address would be listed in a public database, why would I want to send my mobile position all the time?

I'm not trying to talk you out of it, it's just curiosity on my part.

>>797305

>why would I want to send my mobile position all the time?

Aren't there any special provisions for mobile rigs?

>>797356

Not sure what you mean by special provisions?

>>797365

As it's impractical to keep that information updated, mobile rigs could be an exception to that rule

I get what you're saying now. When you are issued a license you have to give an address which is expected to be your primary location of operation. Mobile operation is covered by the same license.

Now I don't doubt the utility of APRS and I know that mobile operation can be triangulated by anyone with the gumption to do it but do I really want to send my mobile location out at regular intervals so that any casual person on the internet can know where I am?

>>797463

You could say that about amateur radio in general. It isn't about what 90% of the community is doing, it's about learning and doing for yourself. APRS is kinda boring but it has its use cases.

>>797473

Hilarious but I decline your proposal.

Bought my first radio. All I need to program a Baofeng is the programming cable and CHIRP right?

Will probably get a nice Yaesu when I figure out what I'm doing

hamfags of the normalfag variety are the biggest bootlickers I've ever seen. Theyre allways on the lookout to turn someone in who uses radio and isnt in their secrit club.

>durrr i payed good money for my license and gear

fuck the FCC for banning encryption, how else are you supposed to run a packet radio website without rampant MITM

>>797640

> Theyre allways on the lookout to turn someone in who breaks the law.

Boo fucking hoo, kike.

>fuck the FCC for banning encryption, how else are you supposed to run a packet radio website without rampant MITM

While I do think the encryption ban is stupid, that's a lame fucking reason. Nobody wants to visit your lame tiny packet website. Packet is used for BBS systems and store and forward. It's a hobby. You shouldn't be doing anything important over the radio unless it's an emergency.

>>797658

>You shouldn't be doing anything important over the radio unless it's an emergency.

I think that is a little short-sighted. People should be using radio to do interesting things, important things. It would go a long way to dispel the 'old guy club' perception.

>>797533

Yep CHIRP and cable is enough.

Works fb out of the box on linux, on windows some of the chinese cables might need some older driver for the pirate chips.

>>797640

Dunno about that.

More like hams don't want people shitting on their bands. Outside of that none gives a fuck more often than not. But it might vary by area and country.

All of the folks I have seen with commercial rigs have the FRS/GMRS/PMR446 channels programmed in addition to hamband stuff. People with DMR rigs used to listen to rentacops and folks like that.

Many of the hams I know frequent 49m and 27.555, not to mention satcom.

So it depends.

But yeah we'd like you not to shit on our bands, its not polite to interfere with others.

And the crypto band is unfortunate, but without that you'd likely see some abuse of the bands.

Obscuring the content is banned, authentication is not.

so SSH with no crypto on the content but with secure auth is OK according to our rules.

Once again depends on your location.

>>797664

We do interesting new things, hamradio is so niche that ppl MITM:ing your packet site is way low in the priorities, at first you'd need a 2nd person to have the same gear and you and to be in range.

Which is rare for packet/data enthusiast.

btw there is also the 8ch.net/hamradio/ board, but it is quite slow.

Removing the legal bindings, is it worth doing a radio transmitter and receievers and then using them as walkie talkie?

Of course, encryption is mandatory, probably with a hardcoded key.

>>797683

Depends on what you consider being "worth it".

Some friends of mine are working on 2.4GHz "walkie talkies" with AES256 stream cipher and speex. tbh codec2 might be a better bet.

Mostly for the fun of it.

>>797640

>how else are you supposed to run a packet radio website without rampant MITM

Micro satellites in the 1.5GHz range. It's what Outernet does.

>>797685

It would be useful in a doomsday or happening scenario (which might never happen).

>>797685

2.4GHz is a pain in the fucking ass, why would you ever try to use that? Wifi uses it, microwaves use it, there's noise EVERYWHERE on that freqnency. They can't pick literally any other frequency to use?

>>797687

Outernet buys bandwidth from Inmarsat.

It's broadcast from geo from a bus sized 100million satellite.

They got over their cubesat idea pretty fast when they realized what linkbudget was and that the satellite would likely not stay up for even a year.

>>797688

Doomsday scenario I'd rather have encrypted VHF than 2.4GHz, like >>797689 says it's shared with everything and has low range.

And in all, actually using the gear and being competent with it means more than the technology used.

One of the reasons why preppers with widebanded HF rigs will just burn the finals in them. It does not matter if there is an FCC or not, knowing how to use the gear is the important bit.

As for why 2.4GHz, it's license free everywhere and it blends in the noise for "tactical" use. where you only want to communicate with people within a building or so.

Operating in TV whitespace or cellphone guardbands would be way cooler, but parts are less available.

>>797675

What is a pirate chip?

>>797700

>they scrapped the cubesat idea

Those fucking pussies.

Recently acquired a Yaesu FT-60, and am looking to get my license soon.

Has anyone here used the FT-60, and if so, how long should the battery last, just monitoring. Mine lasts ~6 to 8 hours without transmitting before the low battery signal comes on.

>>797757

One of my instructors had one and said the charge was about that long.

How long does it take for my license to show? Updated my FRN to have my info on it and I have been checking QRZ daily since I did the exam last Saturday.

>>797640

>fuck the FCC for banning encryption

How would they actually enforce this? I've thought about creating a goonies style note code for a number station. Will the FCC triangulate my position and throw me in jail?

>>797803

Bored old hams absolutely will find and report you. There's a whole subgroup that prides themselves on this

>>797811

I have the occasional daydream of trying to imagine what Radio would be like if TEH MANZ RULEZ didn't exist.

..like every spastic 15 year-old running jammers that they paid a 5000% mark-up for off EBay

>>797753

It would have never worked like they wanted it to.

Physics is a harsh mistress.

You cannot beam 2.4Ghz wifi to cellphones from orbit with a 10cm x 10cm x 10cm cube.

No power, no gain and best of all, no support for "wifi broadcast" reception in consumer equipment.

>>797739

>osmocomBB

Nice, done anything with them yet?

>>797949

Every religious nutjob broadcasting on every band in every mode with 500kW.

Wideband FM on 160m, with a seremon how you are all going to burn in hell.

All of bands from 6m upwards are 1kW long range wifi, its 99% porn, rest is political rants.

All the poor baofeng folks are left in the dust while the other folks run 1kW on every channel, at the same time coz fuck other people.

Or it might go like 11m and 49m freebanders to, who are usually a polite bunch.

From my experience anyway.

In all honesty as long as you behave and don't interfere with others you can do almost everything on amateur radio.

Just look at how much tits the southern european folks send on SSTV.

Zero fucks given, the picture has a callsign.

Realtime SSTV images, but mostly boring.

http://www.g0hwc.com/world_wide_live_sstv.html

http://www.worldsstv.com/

I guess I should SSTV more with spurdo.

Hey you link farmed slightly. Nice job. Maybe someone will fall for it this time. /s

>>797797

>>797757

6-8 hours sounds about right, depending on power-saving, scan mode, battery size, amount of time it's actually opening squelch, audio volume, GPS and bluetooth if installed, etc.

Amateur portables usually don't optimize for power consumption and have tiny batteries compared to commercial/public safety radios. One of the reasons why many hams buy the "professional" gear.

>>798098

> Nice, done anything with them yet?

Managed to spin up an OpenBTS, but other phones can't register in the new net despite seeing it. Maybe it's my cable being too bad for such speed (pl2303).

I'm using sylvain/testing branch because jolly/testing hangs up after uploading both on c115 and c139, anyone here knows how to fix it?

>Want to get into Ham Radio

>Even just the first chapter filled with confusing things that I can't really understand

What do? Reading the ARRL Handbook from 1956 actually seems less complex than the 2016 License Handbook. I don't get it...

>>798098

Don't forget the Degenerates who want to use 'anonymous' radio to buy drugs.

>hand-on-the-cock CypherPunk releases a encrypting Packet system that just needs a computer illiterate to plug their Android Phone's into a ?Beofeng mic input, with bitcoin wallet support, etc., aka a RF WhatsApp

>Dealer uses it to pluck all the sales to teenage off-street kiddies

I'm ready to graduate from my Baomeme and need a recommendation on a better and not-cheaply-built handheld. I'm hoping that I can get a tech license in november, and need something I can use anywhere on the UHF/VHF bands.

also, what antenna and other hardware would I need to transcieve and decode digital formats from a desktop? I got a nooelec ham-it-up & RTL dongle for listening, not sure what else I would need.

>>802199

some clarification, I plan to decode digital transmission from a desktop PC, what hardware do I need to send transmissions?

>>802200 >>802199 (checked)

There are two ways to transmit in digimodes:

1. Good ol' traditional transceiver connected to the soundcard. You'll control the frequency on the transceiver itself (unless you get a CAT interface and a supported rig) and do the encoding/decoding on the computer.

2. SDR. You do everything on the computer, but transmission-capable HF SDRs are very fucking expensive, and most of them are QRP.

>>802200

The common ham text formats use your PC's sound card as I/O. Be more specific if you mean something else.

>>797811

How would they find someone over radio?

>>807951

Hams and shortwave listeners tune around for interesting signals all the time. They WILL find you sooner or later.

>>802200

A radio and a computer, depending on the radio, you may need some other minor odds and ends for switching.

>>807966

>They WILL find you sooner or later.

What? You mean like how number stations are located?..oh wait! They aren't are they?

>>802444

443 MHz license free operation QRP

http://www.ti.com/product/CC1101

CC1101 is highly suited for FHSS or multi- channel systems due to its agile frequency synthesizer and effective communication interface.

Ignore this post

I'm new in radio, I bought a regular chink baofeng, but I don't know what to listen to. I live in western europe.

How do I "scan" channels trying to find anything to listen to? I tried to search for some ham amateur lists, but when I listen on these chans, I don't ear anything...

Seriously, I want to go further, but I first need to listen to something...

Moreover, is there a way to plug my radio to a regular jack headset? thanks.

>>799485

>Well, chances are you bought yourself a 30 dollar ching chong radio called a Baofeng UV-5R (page 3)

>>808010

>I'm new in radio, I bought a regular chink baofeng

>>808004

testing your shilling software?

>>797305

With some APRS rigs you can set position ambiguity, with others you can enter your position manually and just lie if you want.

>>808026

ok, thanks you.

I want to start with a low price thing. Don't except someone who start something he doesn't even know if he's gonna stick with it with hundreds of dollars of materials.

>>808082

>The encryption ban is to protect the bands

Also it exists to discourage spies from using ham radio to communicate.

JOTA is tomorrow

Who here's gonna try to talk to little boys

>>808136

Be sure to drop some red pills on them. The leftist scum are trying to infiltrate.

I considered getting into it but there's not a lot of space on our property, and I don't have time for it at this stage anyway. For now I mostly pick stuff up with a FUNcube and handheld telescopic antenna.

>>808150

One time I heard a ham relay a story about how he was faced down with a sword in London after a road rage incident. I think I've got the recording somewhere.

>>808010

>I bought a regular chink baofeng

>How do I "scan" channels

Le mao

You basically don't, scanning speed on the uv5r is pathetic. You should have bought a cheap sdr instead.

>>808170

I have one, but the funny thing is that I fail to install the driver in the kernel, on gentoo.

>>808082

Thanks for the number station clarification.

>>808086

No, I fully agree with you. I was merely pointing out how accurate the guide author was. >>808026

>>798098

>blahblahblahihatefreedom

All of that shit you're bitching about sounds fucking radical. I'd take a sound version of web 1.0 over HEAD RADIO any day of the week.
