Social Bookmarking

I’ve been using del.icio.us to maintain a list of bookmarks for some time now. I read a bunch of different blogs and news sites that cover a lot of different topics, many of them at least somewhat related to amateur radio, emergency communications, and/or homeland security. One of the cool functions del.icio.us offers is an RSS feed containing any combination of the tags I’ve used to “mark” bookmarks as I save them to my list. You can now see the links I tag (and save to del.icio.us) as I browse, under the heading “Reading List” on the right side of the page. It’s not quite updated in real time, but usually within a few minutes of me adding a link.

I’m using the reading list a handy way of sharing things I’m reading that you might be interested in, without having to post an article that says nothing more than “hey- go read this about -whatever”. As you’re clicking past, I hope you find it useful.

If you haven’t used del.icio.us (or any other social bookmarking site; there are several that work pretty much the same way), here’s an introduction to how it all works.

Transition to Digital TV

Digital TV isn’t technically a ham radio subject, but since it involves RF I consider it related. And, I like new toys. So, I signed up for the coupons the government’s offering for upgrading analog TV’s. I received my coupon a couple of weeks ago, and this week went in search of a digital TV box. I live near a mall, so I didn’t have to go very far; I also had a couple of other consumer electronics related things to look for, and Best Buy was on the way home from work, so that’s where I went shopping.

They make it easy; in front of the department full of HD TV’s (most of which wouldn’t fit in my apartment, much less on my credit card) was a display of Insignia Coupon Eligible Digital TV Converters for $59.99. There’s only one eligible model. So no, you don’t get a lot of choices, unless you want to drive around to different stores checking out what features each retailer’s box includes. (I didn’t shop around.)

Included with the box was a power adapter, an RF cable, an audio/video cable, a remote with battery, and a short & sweet instruction manual. I was pleasantly surprised that I didn’t need to buy anything else to make DTV work. (I will need to do some additional cabling to get my analog DVD player to coexist with the DTV box, as my TV only has a single coax RF input.) Channel programming was automatic, and simple; I did have to set my local time zone using the setup menus. With DTV, I have an onscreen channel guide that shows what’s on now and what’s on next, closed captioning, text, the ability to change the aspect ratio, access to the second audio program, and content access controls.

My antenna (if you want to call it that) is a 4-foot length of speaker wire alligator clipped to my window blinds—so if you have an antenna that barely works now, you may be surprised at what DTV does for you. Using analog, my local channels were generally pretty clear except for channel 3 (which was usually quite snowy). I often had ghosts, and got an occasional burst of audio static. With DTV, I get all of my local channels with no snow and no ghosts.

I also have some extra channels now. Instead of analog 3, 15, 21, 27, 47, and 57, I now have 3-1, 3-2, 15-1, 15-2, 21-1,21-2,21-3,21-4,21-5,47-1,and 57-1. Each broadcaster has slightly different programming available; your mileage here will vary. NBC 15-2 has weather, and WHA (PBS) has different programming on –2, -3, and –4 depending on the time of day. WHA also simulcasts Wisconsin Public Radio (including HD radio) when they’re not showing TV programming on each of those channels. DTV 3-2 carries My Madison TV14, which on broadcast is only available on DTV. As they say, check your local listings.

So, what’s the verdict? Yes, making the change is worth the effort. The sound and picture are better, even on my old TV. There are still times when there’s nothing on—TV is still TV—but by adding one small set top box I was able to increase my options and make my TV useful for a while longer. If only upgrading amateur radio equipment was so easy.

Nationwide alerts for cell phones

From InformationWeek;
link to original CNN article here.

The FCC has approved a new nationwide alert system that will send text messages to cell phones to alert Americans when an emergency, disaster, or attack occurs…

Sounds like this will take some time, since according to CNN the agency that will issue the messages hasn’t been created/decided on yet. I like the idea; I’ve been using Google Alerts and Yahoo! Alerts for some time now for severe weather related messages on my phone. More ways to receive information are always a good thing.

Upcoming events

Here are some upcoming events that I plan on attending; if you’re going to be there and happen to see me, stop and say hi.

Add another band to the list– 6 Meters

Okay, so I don’t have a microphone working for my IC-735 yet, and I have all but given up on the code for now.
I’ve had my eye on the Alinco DR-M06 6 meter rig for a while now, Okay, so it’s not Alinco’s newest model, I like it anyway– it was also slightly cheaper. Since I don’t have a base antenna up yet (here we go with getting antennas airborne again), it’s going to live life as a mobile for a while. I did some Googling about 6 meters, and discovered that WBAY-TV 2 in Green Bay WI has a well written FAQ article about how propagation affects their low VHF signal (they transmit on 55.26mhz). Also found a list of modifications for 6 meter rigs, including the extended receive unlock for the DR-M06T. Didn’t even have to void the warranty. :D

Yeah, there’s a lot of stuff I could have bought that would be a lot more practical in an emergency. Oh well, this radio’s about fun.
