To Use /QRP or not to use /QRP on Low Power Ham Radio Calls

 I mentioned the CWops scholarship yesterday beacuse I was looking at their site for an entirely different reason. The (seemingly?) old saw of whether or not to call /QRP as in KD0FNR/QRP had come up again in a ham radio forum. This time, the converstation on GQRP revolved around whether or not the /QRP designator should be removed from RBN calls. Someone remarked that /QRP might already be filtered on the RBN. I tired this morning wiwth Project TouCans. /QRP is still very much a thing on the RBN.


I'm trying to understand what all the fuss is about. So, if you have clarifying remarks, or even an opinion, please comment! 

Here's what I've got so far:

The people that feel you shouldn't do it feel very strongly that you shouldn't do that. Also, the people that feel very strongly about it seem to only mention it in regards to DX pileups.My fifteen minutes of internet ham radio research led to a SOTA forum post where some (one?) ops revealed they would never respond to callsigns appended with /QRP, while other people seemed not to care one way or another. I've seen concern that logging programs would have a disconnect over /QRP being remembered or forgotten by either station. I generally don't use logging programs, so I don't know??? I found a post on qrper.com about adding /QRP to your SSB calls. Interesting post, as always, but not quite the same thing.

My main usage of /QRP seems to fall outside what anyone is talking about, so I thought I'd write it down here. In my experience, during a contest where you're a sought after entity, the California QSO party for example, very kind, and very beefy QRO stations will carve a nook for QRP stations to hang out in if they're aware of them. In the case of Project TouCans, this made all the difference because on top of everything else, the rig is rock locked. It can't move to a less densely populated spot. But! I called CQ KD0FNR/QRP and wound up with a little slot to transmit in:

Project TouCans signal just fitting between two QRO sigs
Second example of SDR waterfall showing KD0FNR on Project TouCans' signal with just enough room between two QRO sigs
Another example: Project TouCans signal just fitting between two QRO sigs

Everything worked briliantly. I wound up being 4th place in the QRP single op division with a rock locked rig! I didn't expect that to happen at all.

So, I don't know. I don't try to break through DX pileups on most days becuase it's not my thing, they'd have to come to me, and as some folks on the forums  pointed out: QRP. But /QRP sure was handy in getting a little room to work. Also, the other ops were incredibly kind! Ham radio's really nice.

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.
