Low Slung Dipoles and How Project TouCans Reached California from US-5906 on a POTA by a Cliff

We got to camp a bit more in the middle of nowhere than we usually do while traveling across Utah last weekend. My partner found the Burr Trail Scenic Byway. I've looked for a route across southern Utah for the last several years, but had somehow missed this really nice, well-paved, little road.

We camped at the foot of an East-facing cliff, and the QSO map for the POTA reflected that fact pretty nicely:

Based on this overall map, I didn't think we could hit the West Coast because of this cliff face.

Almost all of the QSOs and spots paid attention to that cliff face. And then, there was N0OI:

How? How had the signal cleared the cliff and skipped out to Perris, CA?

Using data from the Boulder, CO ionosonde, at the time Project TouCans was spotted in California, the F2 layer skip is modeled in the gif below. Note that it clears the mesa, (just barely.)

The other skip off to the Southeast was headed to the Cayman Islands. All of the skewing around is to convince myself that the the F2 path lines up with the path to the spotting station. You'll notice that there's a slight elevation offset that needs to be fixed.

More Notes on the POTA

I blew out my knee a bit sitting on the ground outside the tent for a three hour podcast interview on Friday night, consequently, the gang did most of the station set up including deploying Project TouCans in its dipole. Throughout that process, the family pup kept me company

When the gang were done, we had what, for Project TouCans, was a fairly typical antenna height of about five feet over the ground

One really interesting aspect of this POTA was that I didn't have the ability to Internet spot myself. Frankly, I wasn't sure it was going to work out at all, and for the longest time from about 00:02 GMT 24-05-27 till 13:50 GMT on the same day, it didn't. (Yes, I was asleep for most of that time with the rig turned off.) And then! Thanks—I think—to a few neighboring POTA stations, ops started to realize that TouCans was there! It may have also helped that my first QSO with WI5D was a bit of a rag chew.

Also, while hanging out on the cliff, the gang found an interesting mineral/quartz/mica/I don't know sample of rock. It was flat, broke easily, and contained pockets of crystals that were translucent. Any ideas what this might be?

For the moment, I'll leave you with this map of all the spots and QSOs for the POTA over the course of the evening, and into the next morning. Click play, then move the time slider all the way back to the left to see all the spots and QSOs with their associated F2 skips at once. Then, you can hit play to see how it all unfolded. (Keep in mind, the overnight nothingness is included in the map. You may want to skip over that.)

As a final note, while I'm waiting for all the F2 data to come back, I've been trying to convince the gang that the F2-height datastream from the Boulder, CO ionosonde

is in fact entered manually by a room of accountants not unlike those in John Wick, but to no avail. I guess they're just digital natives :)

Ah! And credits to where the ionosonde data actually is coming from

This was made possible with data collected by

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 concept very sim

Missed you and your gang on this one, but was stoked to get you in the log from your 5/31 (UTC) activation in Colorado. The TwoCans sounded great back here in SF. The geology in this post is amazing, almost to the point of distraction. 73 and safe travels. de W6CSN
