Things I Learned: Using Datasette to search for Ham Radio QSOs in a Date Range

 I've been doing a lot of amplifier testing over the last week with the Tuna Topper as part of what has become Project TouCans. It's led to many more QSOs—meaning, more than one per week—from the house. I maybe haven't remembered to log them all, and so I wasn't too surprised when I saw that N2AKJ had logged a Parks on the Air, (POTA), contact with me last Thursday when they activated K-2114 Nissequogue River State Park. Still, since I didn't remember the QSO, I wanted to make sure I was at least on the air. And.... There's an app for that!

Using the RBN network data automatically accumulated by rm-rbn-history about QSOs and RBN spots from my callsign—KD0FNR—served through datasette, I was able to determine if I'd been on the air when the QSO was logged. Spoiler alert: I was.

Understanding the SQL formatting to get the information was a bit tricky, so I'm documenting the SQL statement here so I can go back to it later.

select rowid, id, tx_lng, tx_lat, rx_lng as longitude, rx_lat as latitude, timestamp, dB, frequency, Spotter from rm_rnb_history_pres where timestamp > :date and timestamp < :date2 order by timestamp desc

Which doesn't seem tricky at all now that I've simplified it, but... It took 10 minutes of research and experimentation to get there in the first place? Not enough coffee? Maybe. Either way, next time, it'll be easier.

The query quickly netted the following results during the time the QSO with me was logged:


And did the Rockmite and TunaTopper in their 'Tuna Soup' incarnation reach New York that day? 

Yes it did! New York and lots of other places!

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:

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
