Pony Express POTA Activation with Project TouCans After all the Rain

 Happy Holidays!

It's been a rainy few weeks here which, with the holidays, has led to less playing radios. I finally got a break in the rain one afternoon this week and headed out to play radios and to try my new Christmas present, a Lumix DC100 camera. I've been playing both with how I want to use the camera and how I want to publish the results. Expect to see more notes on both of these things.

Park: US-4578 Pony Express National Historic Trail

I headed to the end of Pier 7 which is on the Pony Express National Historic Trail. The pier was crowded, what with the sun being out and the really nice view back towards town.


I took the BART downtown, made a brief stop at The Palace near Montgomery Station for a cocktail and to make sure I knew how the camera remote control via smartphone worked, hopped back in the BART tunnel, popped back up at Embarcadero, and walked the rest of the way from there. Here's a look at exiting the BART.


Radio Details:

I was still using a tent pole as a mast. TouCans did great though! It chugged along with very little noise and reached LU4HK in Aregentina, making a greater than 1000 mile per Watt QSO.

Happenings of Interest 

I played with what output levels the camera needs to do speaker to mic audio transfers. They're kind of high. Everything worked well in the end.




It was fun getting to watch  ferries and cargo ships come and go.

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...

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 ...

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:...
