Trashcan Portable: Project TouCans POTA at US-3012 Franklin Mountains State Park

 I didn't manage to activate this El Paso, TX adjacent park this time, but the innovative antenna KO6BTY and I prototyped back in December did a pretty good job in kinda lousy band conditions! Then, I had to flee the dust storm and head for Albuquerque to catch a plane the next morning.

Park:

US-3012 Franklin Mountains State Park near El Paso, TX.

As is usual for my trips to New Mexico, my radio ops over the weekend were all car transit.

Radio Details:

Rig: TouCans and a Stick on the only band it uses right now: 20 meters

The radio worked well considering the antenna was taped to a rest area trash can. Propagation in general was bad, but I learned a few ways to make things better with respect to the trash can. The rig does better when the insulated antenna wire is not touching the trash can lid. Go figure. It makes sense, but still. Go figure.

Here's a closer view  of how the antenna was mounted, although you'll notice the antenna is disconnected at the time the photo was taken.



Happenings of Interest 

There was a highway closing dust storm predicted later in the day, so I had to cut my activation short. Sure enough, on my drive up US 70, there were points where I had about fifty yards visibility in front of me.

What interests me the most about this location is that if you zoom in enough on the map below, you'll see that the rig was having to hop a failry steep embankment to make any of its QSOs, and it had few if any problems pulling that off.




Here's what the transmit site looked like with a bit of an explanation of the terrain.

Cool Math Tricks: Deriving the Divergence, (Del or Nabla) into New (Cylindrical) Coordinate Systems

Now available as a Kindle ebook for 99 cents ! Get a spiffy ebook, and fund more physics The following is a pretty lengthy procedure, but converting the divergence, (nabla, del) operator between coordinate systems comes up pretty often. While there are tables for converting between common coordinate systems , there seem to be fewer explanations of the procedure for deriving the conversion, so here goes! What do we actually want? To convert the Cartesian nabla to the nabla for another coordinate system, say… cylindrical coordinates. What we’ll need: 1. The Cartesian Nabla: 2. A set of equations relating the Cartesian coordinates to cylindrical coordinates: 3. A set of equations relating the Cartesian basis vectors to the basis vectors of the new coordinate system: How to do it: Use the chain rule for differentiation to convert the derivatives with respect to the Cartesian variables to derivatives with respect to the cylindrical variables. The chain ...

The Valentine's Day Magnetic Monopole

There's an assymetry to the form of the two Maxwell's equations shown in picture 1.  While the divergence of the electric field is proportional to the electric charge density at a given point, the divergence of the magnetic field is equal to zero.  This is typically explained in the following way.  While we know that electrons, the fundamental electric charge carriers exist, evidence seems to indicate that magnetic monopoles, the particles that would carry magnetic 'charge', either don't exist, or, the energies required to create them are so high that they are exceedingly rare.  That doesn't stop us from looking for them though! Keeping with the theme of Fairbank[1] and his academic progeny over the semester break, today's post is about the discovery of a magnetic monopole candidate event by one of the Fairbank's graduate students, Blas Cabrera[2].  Cabrera was utilizing a loop type of magnetic monopole detector.  Its operation is in...

More Cowbell! Record Production using Google Forms and Charts

First, the what : This article shows how to embed a new Google Form into any web page. To demonstrate ths, a chart and form that allow blog readers to control the recording levels of each instrument in Blue Oyster Cult's "(Don't Fear) The Reaper" is used. HTML code from the Google version of the form included on this page is shown and the parts that need to be modified are highlighted. Next, the why : Google recently released an e-mail form feature that allows users of Google Documents to create an e-mail a form that automatically places each user's input into an associated spreadsheet. As it turns out, with a little bit of work, the forms that are created by Google Docs can be embedded into any web page. Now, The Goods: Click on the instrument you want turned up, click the submit button and then refresh the page. Through the magic of Google Forms as soon as you click on submit and refresh this web page, the data chart will update immediately. Turn up the:...
