I can has Wifi thethering?

So, I finally got off my ass and rooted my phone. I don’t like phones, I don’t like smart phones. I was totally fine with my old flip phone last year, then my wife bought me this thing. Now, don’t get me wrong, I’m grateful, and having a so called “smart phone” has saved my ass once or twice. But on the flip side, so much hidden junk and bloat in it that I don’t exactly trust it.

Now, yes, I rooted it. I still don’t trust it, even after removing some bloat. Only way I would is with a custom kernel, built from the ground up by me. But, that is waaaay too advanced for me. So instead, learning to actually root the thing(no warranty on it anyway. Definitely wasn’t top of the line last year, or maybe even 2 years ago). But now I have wifi tethering. If you’re not sure what it is, it means I don’t have to pay any stupid phone service provider extra money to be able to use my phones data plan on a more convenient platform. I own my phone outright, and now I almost really do.

And that is why I love radio. If I want to share data with someone, I just schedule a time and frequency with them, hook up the computer, and go for it. If I want to talk to someone, I talk. Of course, it’s not like a phone where I just dial the number, but that is what an SOI is for. That is what scheduled nets are for. Of course, when you go with a TOC setup with dedicated RTO’s, it’s as easy and hitting the PTT switch and calling for them. But that is something slightly different.

So yes, I thought I’d mention that. I’m actually quite pleased it worked. I do recommend rooting your device and learning how to remove bloatware and extra junk safely(remember to back it up first!), and unleashing the potential, such as not having to pay for a service you should be getting anyway. You’re paying for the data. You paid for the equipment. I’ll be damned if they won’t let me use it.

Digital HF Transmission Methods vs. IMC

Just did a test with fldigi and my phone, generated a 50wpm cw message to a wav file, tested the wav file by importing to fldigi, then transfered to my phone and played next from there into the built in microphone on my laptop. Picked it up just fine. So maybe 50wpm cw bursts are doable, and doesn’t appear to use much more bandwidth. Something to add to the commo book.

What follows is a belated response to a recent comment regarding Morse burst devices.

Most folks don’t realize that international Morse Code (IMC) is a very early form of binary communications; Dits and Dahs or ones and zeros.

All Amateur (Ham) license holders before 2007 and every Special Forces 18E (Communications NCO) before 2002 were required to learn IMC. Why? Because prior to Satellite communications and the advent of some of the newer software based data transmission methods now available, it was the preferred method of making reliable long haul HF Communications. IMC is more reliable by magnitudes than voice communications across the HF spectrum. It still remains, in my opinion, THE method requiring the least amount of fragile (breakable) equipment. Since the code requirements have been dropped on the civilian side, very few ham operators are willing to invest the time to learn a new language (IMC). In my…

RF-1944-150 pt. 1

So, I was messing around with a Harris RF-1944-150 over the weekend. Very interesting. It’s a Inverted V dipole designed to work between 2-30 MHz. The specs say it weighs 9 pounds for the 150 watt version, but when I weighed it, it was a bit more.

When it came time to test for SWR on the bands, I came across something odd. on 80m it showed as 3:1, on all the other bands I tried, it was showing a 1:1. I call shenanigans.

The issue I’m running into is that I don’t have an antenna analyzer, instead I’m using an external meter with my radio (LDG Electronics with Yaesu 857D). So until I can actually get my hands on an antenna analyzer, I’m stuck wondering how accurate that is. So, maybe soon-ish I’ll find someone who will let me borrow theirs. Or I’ll just buy one.

Below is the data sheet of the antenna in question. Seems nice, but it takes up more space than it looks when set up. More to follow, eventually.

–INSERT AWESOME SOUNDING TITLE HERE—

So, here I stand eating my breakfast after PT(You did do PT today, right?), thinking about the direction this little hole in the interwebs is going. I think I got it figured out, and maybe somewhat of a why.

So, I like radios. Obviously. I (kinda) like .mil equipment. Mainly because I work with it on a day to day basis. And I’ve noticed a decided lack of adapters for use. Makes sense in a way, because most of the civilian stuff is quite good, and why would you want to use an H-250 (and take the time to make an adapter so you can use it) when you’ve got you’re gear that was designed for your radios?

Well, I’m a firm believer in battlefield acquisition. Especially in a guerrilla warfare environment. Eventually you’re going to need to resupply on ammo, or your radio is going to take some frag during a fight and you will need to replace it. Or your microphone or headset designed for your rig is going to take a dump. Well, without normal supply chains, what can you do?

For starters, if you have an adapter, you can use the .mil 5 or 6 pin connectors. And most of that gear is pretty tough. And second, it allows for a quick disconnect type configuration, so if you need to switch them out, it’s relatively quick. With my EFJ, I can go around with my Liberator 2’s, and when I get back inside, I can quickly switch to a speaker mic and set it down so I don’t have to be right next to it. A lot of the time, I tend to leave the porkchop on when I go outside so I can set it down and listen with the volume high. That thing can get kinda bulky and in the way when you’re moving feed bags around and such.

So, just wanted to get what’s been bouncing around in my mind out of there, figured this was a good place to do it. More to come, hopefully soon.
