2 Meter J-Poles

First of all, I want to say thanks to the staff of Hamblog.com for the reintroduction of their fine website.

I went to the Cary, NC Hamfest this morning. This is the same hamfest where I passed the Technician class license exam last year. That means that I have been a licensed ham for one year now. Hooray!

I was mostly broke today, so I didn’t pick up anything tremendous. I just scrounged around, looking for connectors and doodads that I didn’t want to buy are Radio Shack. I did pick up a nice 1:1 balun for $1. It looks to be in good condition and is cased inside PVC. I also picked up some cheap 300ohm twinlead. 100′ for $2!

I bought this with dipoles in mind, but I remembered seeing a website or two about 2-Meter J-pole made with this stuff. I didn’t currently have a working 2-meter antenna. My magmount base is screwed. I haven’t found out where though. I just know that the SWR is shot to heck. I went to this page first: http://www.mvw.net/radio/jpole.html. The illustration was kinda confusing, but this one: http://www.bloomington.in.us/~wh2t/Jpole.htm helped fill in the gaps.

I built, and taped it to a tall cardboard box. It worked! My signal report was weaker than I liked, but it was better than nothing.

Windows Longhorn 5203 Screenshots

Here are a few free screenshots of the new Windows version that is due out next year. It will be called, “Longhorn”.

I see a lot of “eye candy” here i.e. a lot of fancy graphics. The problem is that it will require equally fancy hardware to support it, not to mention the cost of the OS itself.

This is Fedora Core 4:

This is Knoppix 3.9

This is Mandrake Linux using Super Karamba

This is an unknown distro running the Enlightenment Window Manager

Both Linux and Windows offers some pretty impressive eye candy, but two things stand out.

1. In Linux, the desktop is so customizable, that you won’t believe it. Everything is changeable, and you don’t even need to be a programmer to do it.

2. You can have an impressive looking (and functional!) desktop with very modest hardware requirements under Linux. If you have anything less than a 1Ghz PC, I would bet that you may have to upgrade your PC in order to run the newest version of Windows. This isn’t necessarily the case with Linux.

Paranoia is not education

There’s been a lot of talk going on in the news about identity theft. I understand that this is a terrible crime that can leave a person penniless and in dire financial straits. The main culprit, of course, is the internet. The news reports are full of “Beware of this” and “Beware of that”. My beef, and this is probably something inherent in TV that I have long been immune to is that important information like this is given 30 seconds to 2 minutes on the nightly news. That is not enough time to educate anyone about the dangers of almost anything. The only thing it can do is spread fear, and that is no way to combat a problem.

For example, on NBC’s Today show suggested staying away from any website that asks for any personal information such a mother’s maiden name, etc. Okay, big dumb move. Legit companies like eBay and Amazon.com ask for that kind of information as a security reminder. They’re goal is to press you with information and make is sound as scary as possible. Fear tactics do not make for good consumers.

Here are a few good tactics that they won’t tell you in the news.

1. Get rid of Microsoft Outlook and/or Outlook Express. Hackers and virus writers sometimes specialize in hacking this software. It also has inherent vulnerabilities that make it’s users specially at risk. Get a good email program or service with built in spam blocking. Thunderbird is great, Eudora is good, and Lotus Notes is acceptable.

2. Read Snopes.com and Symantec’s Hoax page, and be aware of able to identify legit email from spam at a glance. No, you have not won a lottery in another country, nor is Bill Gates wanting to send you $50 for forwarding an email. Most importantly, Apu Nahasapeemapetilon from the country of Durkadurkastan does not have $3M for you if you help him transfer it to another bank account.

3. Make you password difficult. For example, “L1Qwpp01G5woS” is a good password. It is difficult to remember, but it is also difficult to crack. “jason77” is not a good password, neither is the word “password”. Make your password difficult, write them on 3×5 notecards for safe keeping and lock them up in a filing cabinet or lockbox when you are not using them. No hacker is so good that he can use his computer to look through your locked filing cabinet.

4. Pay your bills online. That’s right, I said it’s okay to make purchases online. If your bank is reputable, then they may offer this service for free or for a small cost. Data encryption in most banks is probably very good. If your local utility companies can take a bank draft, then do it. It will save you time and money in the long run.

5. Learn how to use encryption software. By all means, read up on how to use GnuPG or PGP. This is one powerful tool that can make almost any email program built like a TANK. Is it complicated? vYes it can be, and you might have to learn something new. It is worth it in the end especially if you use programs like Quicken or Microsoft Money. I think I’ll write up a mini howto on how to use it one of these days.

6. Finally, some of the ideas that were posted on some news site isn’t so bad. Owning a shredder is definately a plus, but how about this: Buy an el-cheapo flatbed scanner, scan those old bills that you want to keep to image files, encrypt the files, and save them to CDROM. If the CDROM gets stolen. It’s okay. The encryption that GnuPG and PGP uses is government strength. As long as the hacker doesn’t have you private key AND your password, the data there will do them no good.

You might have to do some research to accomplish some of these tips. You might have to learn something more about computers and the internet. That’s okay. An educated consumer is a safer consumer. Don’t be afraid of the internet. Be smart enough to navigate it safely.
