From Computer DVI To HDMI Port

Here is a solution when going from a computer with DVI port to a monitor, HDTV, or projector with HDMI port, or from a computer, Blu-ray player, TV box, or game console with HDMI port to a monitor with DVI port.

Here is the product as described: Cable Matters® (2 Pack) Gold-Plated DVI to HDMI (Male to Female) Adapter.

This fix may cover the video but not the audio. It shouldn’t be a problem, since separate audio cables can be used anyway.


A 20 Meter Vertical Made Out Of Copper

My aim was to build a 20 meter vertical out of copper, since copper is normally a very good conductor. Recently I bought a couple sections of copper pipe and clamped them together. The sections were 10 feet in length.

I may later put up some elevated radials, but for now I am experimenting with a type of fence for the counterpoise. It is described as the following: Feedlot Panel, Cattle, 16 ft. L x 50 in. H.

After a few hours of putting it all together, I turned on my HF radio and tried to find resonance. The low portion of the 20 meter band seemed to be the sweet spot.

The band was in pretty good shape that particular day and I received a 5 by 9 signal out of Croatia. Actually it was ten over nine. I knew my 20 meter vertical was a keeper, especially when there was no trouble in getting a very low SWR reading.

The copper 20 meter vertical played well on the 17 meter band.

I would like to suggest another purpose for the cattle feedlot panel. I used it as a reflector for my home brew HDTV antenna, with stunning success I might add.

Digital Is Now Open Source For Ham Radio Operators

As an amateur radio operator, are you interested in digital voice for HF radio? What if you could go digital for just a couple hundred dollars? Thanks to new open source technology, this has become a reality. This is innovative and something to keep an eye out for. Digital technology for VHF radio is coming soon. All open source of course.


Why use FreeDV?

Amateur Radio is transitioning from analog to digital, much as it transitioned from AM to SSB in the 1950′s and 1960′s. How would you feel if one or two companies owned the patents for SSB, then forced you to use their technology, made it illegal to experiment with or even understand the technology, and insisted you stay locked to it for the next 100 years? That’s exactly what was happening with digital voice. But now, hams are in control of their technology again!

FreeDV is unique as it uses 100% Open Source Software, including the audio codec. No secrets, nothing proprietary! FreeDV represents a path for 21st century Amateur Radio where Hams are free to experiment and innovate, rather than a future locked into a single manufacturers closed technology.

The Latest Sniper Fire Controversy (Helicopter This Time)

MAKING A DIFFERENCE: Maybe it’s time for a vacation with the Clintons…

All the world’s a stage and all the men and women (reporters) merely players (liars). “Objectivity is a central philosophical concept, related to reality and truth, which has been variously defined by sources.” This is the quick Wiki definition. Basically this is the truth, reality, with verifiable sources. So what’s all the the fuss about the Brian Williams helicopter episode? It’s journalism as you like it.

Lights. Camera. Action. Choppers.

Seriously, a laugh can be shared. A New York Times piece informs us that NBC should investigate this chopper issue. And this poses the obvious question. Don’t all reporters lie at some point in their career? Maybe just a little white lie?

Potentially there’s motivation behind this crude allegation. Just maybe Brian is paving the way for Hillary. Just maybe Brian is trying to say that a little sniper fire controversy is good for ratings. Maybe this is good for show biz.

That’s the signpost up ahead – your next stop, the Twilight Zone! — Sponsored by NBC Playhouse

You can visualize it now. Brian begins to cry for fear of losing his job and Hillary comes to his rescue. She confesses that she too had once been caught up in a sniper fire controversy, while she sports a Hillary for prez sticker displayed on her forehead. Both exchange their sympathies and the audience is emotionally connected.

As an added token, they could bring Bill out on stage. With the left hand clinched in all his posterity and a prez sticker proudly displayed on his forehead, Bill could resort to playing saxophony. Maybe someone could insert a fake cannabis stick behind his ear and address the admission of not inhaling. Bill could wipe the tears off Brian’s face for theatrical gesture.

While we’re at it we could have Sarah from Alaska straightening a picture in Brian’s office. She’s not choosy and she has no problem being a reporter or running for president. You see the weather is not so great in Alaska.

Not to offer any advice to anyone, but some may feel that Brian is qualified for president, or at least vice president. He’s comfortable in a suit, he has gone through the sniper fire campaign, and he’s comfortable in front of the camera.

Warning. The risk of reporters or politicians stretching the truth is great. You have been forewarned.

On a more sober note, one wonders why Brian is under attack while more relevant news is being ignored. It would seem as yet another distraction, and by now viewers are getting used to these tactics. Why the diversion this time?

Could it be a ratings problem? Who will be the permanent replacement for Brian?
