I wonder if those streaks are not water droplets aligned along electrostatic lines of force.

MV,

Really cool stuff. A little over my head at this time(no pun intended). I can see if you were out in the blue water cruising this would be nice to have and look at.

You may think you are talking to yourself, but over 500 views shows people are definitely "listening". I've been watching closely. Looks like really cool stuff I'll want to get into one day.

Thanks for the post, you have certainly got me to thinking. I have spent some time researching this system and I believe I can construct one like it. The only issue is how to wire the cable into the antenna tubing. I have seen several illustrations but still can't figure it out. Can you explain?

Thanks, MV

I've been looking for plans for a QFA ever since one of our "old timers" where I worked did a presentation for our local ham club on it. The plans you found are about the most aesthetically pleasing I've seen so far, so the Admiral would probably approve it. I just don't know if I have enough room in the mizzen mast for another 50 ohm coax...

Randy: Here is a link that discusses the wiring issue you mentioned: qha. That is a plan you see in different forms all over the net. That specific article though lists a couple of decent references at the end. I do not know what you have already seen out there, so I dont want to throw alot of useless stuff at you.

Cap'n John: I don't know the technical stuff -- but if you get too far afield between the antenna elements and the receiver, you might need a 16dB gasfet preamplifier. I think Bob at National RF makes one. SAT.

I found the instructions here http://web.ukonline.co.uk/phqfh/qfh.pdf to be easy to understand, but I simply did not want to mess with bending copper tubing. Hence, I just bought the antenna.

February 4th 2009 coming up!!! NOAA-N Prime!!!

Ok, this post does have DIRECT relevance for sailors and mariners (what is the difference between the two??).

Brand spanking new NOAA POES (Polar Orbiting Environmental Satellite) will be launched!


NASA - NASA, NOAA Set to Launch NOAA-N Prime Satellite

It will be carrying emergency locator stuff built by France.

"NOAA-N Prime has instruments that support the Search and Rescue Satellite-Aided Tracking System (SARSAT), part of the international satellite system that includes the Russian provided satellites (COSPAS). Since SARSAT was established in 1982, NOAA polar-orbiting satellites have been detecting emergency distress beacons set by aviators, mariners and individuals in remote locations and relaying them to ground stations so that rescue teams may be dispatched. More than 24,500 lives have been saved through the satellite based Search and Rescue system to date."

SWEET!! I cannot wait to get the first sets of transmissions from this newest addition (Eventually will be called NOAA 19).

This is some exciting stuff!!

And ..... ummm...... it affects sailing.

Michael

First NOAA-N Prime image using Vegetation Sensors

NOAA N' was launched a few days back. I have been having some issues getting the keplarian elements correctly installed on the software, so I disabled the map overlay for this image. The grid was way off.

For the first few weeks, the new satellite will be sending data on the vegetation sensors. So here is my very first image from our newest eye in the sky.

The cloud detail is exquisite on the infrared channel. Wish I had better understanding of how they are using IR. The old IR looks less detailed than the new images.

First colored image is using the vegetation sensors. The second image is the raw feed from N'. As you can see, the may overlay is screwed up.

Keep it up MV... We're monitoring...

Hey MV,

I've been following since your first post on the subject. Please keep posting as you learn more. This looks like really useful stuff, and I hope to follow in your footsteps when I have more time to investigate!

There is not such thing as too much information, only minds that are too small to process it all!

Don W.
