The Three Laws of Electronic Measurement

On Saturday, I had the privilege of talking to a group of radio amateurs on the topic of electronic measurements. I opened the session with a short discussion of “why do we even need electronic measurements?” This was captured in three “laws” listed below:

Bob’s First Law of Electronic Measurement

With electricity, most of the time we cannot observe what is going on without measuring instruments.

Bob’s Second Law of Electronic Measurement

When we can observe electricity directly, it is often a bad thing.

Bob’s Third Law of Electronic Measurement

Lord Kelvin was right

You know you’re a Ham when ……..

So I'm driving to work this morning; and when you commute to work every day, you get a real good chance to look at the behinds of cars that are in front of you.  As I come to a red light and come to a stop, I notice the car in front of me has one of those vinyl decals on his rear window.  It looked like this - but you have to picture in your mind's eye that this was all surrounded by the entire darkness (blackness) of his tinted rear window.

So I immediately start thinking ....... "A A" 

What the heck does "A A" stand for?  "Alcoholics Anonymous"?  "American Airlines? "Associate in Arts"? "Alcoa Aluminum"?

Then it struck me - the owner of the car was of Norwegian descent !  That's the flag of Norway in reverse and not "A A".

I guess that's when you realize you've either been at this Morse Code thing too long; or maybe you just need that first cup of coffee of the day.

Things On The Air (TOTA) Launched

The Sundance Mountain Radio Association (Palmer Lake, CO) today announced the creation of the Things On The Air (TOTA) program. The radio association’s Need More Lists Committee spent the past year analyzing the effect of various “on the air” programs, including the Islands On The Air (IOTA), National Parks On The Air (NPOTA) and Summits On The Air (SOTA).

The overall trend is clear. The ham radio community used to be satisfied with the basic DXCC list (a list of countries that aren’t really countries so we have to call them entities). But over time, additional lists to be worked have been created. For example, the Islands On The Air (IOTA) was created in 1964. More recently, the Summits On The Air program was established in 2002. It seems that every year or so we hear of another “something” on the air program. Even the normally docile satellite grid chasers created a Walmart Parking Lots On The Air (WMPLOTA) event.

Unfortunately, this has created a miss-mash of programs with inconsistent and conflicting rules. The Need More Lists Committee concluded that the best solution to this problem is to fast-forward to the likely end state: pretty much everything can be put on the air. Inspired by the latest technical hype called Internet Of Things (IoT), the committee named this program Things On The Air (TOTA).

To be comprehensive and inclusive, the TOTA program is based on the existing Maidenhead Grid system. There are 324 fields defined (AA through RR), each having 100 squares (although they really are not square). Each square contains 576 subsquares indicated by aa through xx. So using the six-character locator results in 324 x 100 x 576 = 18,662,400 unique locators. Or, as the Committee likes to say, about 18 million locators. In North America, the six-character locator represents a rectangle about 3 miles by 4 miles. This raises the question of how many things need to be on the list inside a typical 3 x 4 mile rectangle. An in-depth study revealed there are a lot of things that might need to be listed in even a small area.

For TOTA to achieve the vision of being the “last list of things on the air”, it must accommodate an unlimited number of listed things. To start out a 15-digit serial number is appended to the 6-character locator to indicate a TOTA thing. As the program grows and new Things are added to the list, the 15-digit number can be extended indefinitely.

Here’s an example listing of some of the first TOTA designators:

Locator  Serial Number      Description
DM79nb   000000000000001    Walmart Parking Lot
DM79nb   000000000000002    Home Depot Parking Lot
DM79nc   000000000000001    Leroy's home QTH
DM79nc   000000000000002    Leroy's barn
DM79nc   000000000000003    The big tree behind Leroy's house
DM79db   000000000000001    Charlie's home QTH
DM78lu   000000000000001    Pikes Peak Summit
DN70di   000000000000001    Rocky Mountain National Park

When making a valid TOTA contact, the activating station must give a signal report and the TOTA designator: 6-character locator followed by the serial number (at least 15 digits but may be longer). The official TOTA list is currently be maintained on an Excel spreadsheet on Leroy’s computer but a HDFS database is under construction to handle the expected large dataset.

The Committee requests the help of all amateur around the world to submit additional entries into the TOTA list. Eventually, this process will be automated via the web site but for now submissions can be made in the comments field below.

SOTANA May Be Right For You

DX Spray …. it works!

Unlike the grand vistas that Jim W1PID encounters in the beautiful locales of New Hampshire, the views that I am afforded during my lunchtime QRP sessions are a bit more urbane.  However, as the season changes along with the leaves, even in a suburban setting there is beauty to be found:

Not bad for a parking lot view, eh?

As I was setting up the station, I noticed that the "stick" part of my Buddistick was ......well, rather sticky. I happened to have a can of this in the trunk, so I applied a bit to the whip and then proceeded to rub it in using some 3" gauze bandage from my First Aid kit.  Hey, you use what's on hand!

Little did I know that WD-40 actually stands for "Whopping DX - 40 Meters".  I didn't get on 40 Meters, but the can didn't know that, and the DX Spray seemed to work equally well on 15 and 17 Meters. In short order, after applying this miracle spray to my Buddistick, I worked T47GDXC, SM3PZG, RA1AOB and TF4X all in the space of about 15 minutes.

Who knew?  If I was aware of what WD-40 really stood for, I would have been applying it to my antennas years ago!  Just think ..... all the wasted time, all the wasted opportunities!  I could be on the DXCC Honor Roll by now.

Some would attribute my success today to the sun and something called "improved band conditions". But I, for one, know better. I have learned the secret of the magic "DX Spray".

Sob ....... weep!
