State QSO Parties come in all shapes and sizes but the intent is always the same — to stir up activity on the air and to have fun in the process! Approach these as serious contest activities or as a casual event punctuated by a little scorekeeping. Your choice. There are plenty of reasons to participate, but if you need more convincing, allow me to share with you five GREAT reasons why you should get in the party line!

1. It’s good practice for big contests. You get a chance to see how your station performs, and identify your weakest link. You can stress test that new paddle or audio chain, make certain your logging program is working properly with your equipment. In other words, a State QSO Party provides an excellent trial run for your budding contest station — if that’s your cup of tea.
2. Finish off your WAS basic award by snagging that State that you just never seem able to confirm. When dozens of operators are calling ‘CQ’ in their own QSO Party, from whatever state you might still need, chances are good that you will log a bunch of them, increasing your odds that at least one will confirm your QSO. Same goes for band and mode slots. Say you have the basic WAS award, but now you want to confirm all of them on RTTY. Or 80M CW. The State QSO Party’s will turbocharge your efforts to reach those goals.
3. County hunters lick their chops over QSO Party activity. And with good reason. Those who organize a QSO party usually go out of their way to make certain that every county in their state is activated. Even if that requires engaging multiple “rover” stations who drive to and operate from counties that may have a zero ham population and are never active. And bonus, some of these rover station operators find their mobile/portable adventure so enjoyable, it becomes the primary focus of the hobby for them. It’s just another of the many facets of amateur radio.
4. It’s a stress-free way to collect wallpaper, plaques, and bragging rights. Most QSO Party’s offer awards and plaques for top scores. And in many cases, you don’t need the biggest gun in the hunt to bag one. Do a little research and consider focusing on specialty entries. Enter as ‘QRP CW’ for example, and you will compete in a smaller pool while the plaque for taking first place in that category is even sweeter.
5. Participation will make you radioactive! It’s no coincidence that those who rarely make use of their radio are often the most vocal critics of – well – almost everything about the hobby. Meanwhile, those who are frequently active on the air are too busy enjoying the hobby to waste time picking nits.

Operating in State QSO Parties couldn’t be easier, especially for those outside the state where the exchange is usually just signal report, your state or province, and sometimes a sequential number that begins with one and increments each time you make a contact. Inside the state, operators will also include their county. You can submit your log electronically (usually Cabrillo format) or send in paper, the old-fashioned way.

Read the rules, sketch out a plan, put in the effort, and then watch your logbook fill to overflowing.

(adapted from a recent issue of Quintessence, a weekly, personal letter about amateur radio)

“Hey, Dad …… do you have a meter that will read really small voltages and tiny amounts of current?”, my son Joseph asked the other week.

“Joey, I’d better! I’m an Amateur Radio operator, and I was an electronics technician for 22 years.”, I replied.

And so began the 2014 8th grade Science Fair project. My son decided to see how the pH of a fruit or vegetable would affect its ability to generate electricity. His hypothesis – the more acidic the fruit/vegetable, the more power would be generated.

The materials were an apple, a lemon, a pear and a potato. A head of red cabbage was procured to act as a pH indicator. Zinc screws and 3 inch pieces of #10 gauge copper wire served as electrodes.

Before we began generating electricity, my wife boiled some leaves from the cabbage in a pot of water. The resulting liquid would act as our litmus paper.

I stuck a screw and a piece of the copper wire into each piece of produce. The positive lead from the meter went to the copper wire and the negative lead was attached to the zinc screw. We measured both voltage and current, to be able to calculate Watts.

A teaspoon of the cabbage water was put into four glasses. Juice from each piece of produce went into the purple cabbage water. If the cabbage water turned blue, it would indicate a base. If the water stayed purple, the pH would be neutral. An acidic pH would turn the cabbage juice pink.

From lowest output to highest were – potato, pear, apple, lemon.
And in turn, the potato had the lowest pH, while the lemon had the highest. The voltage and current readings followed the pH indications. It seems my son’s hypothesis was correct!

Now all Joey has to do is make a graph, print out the pictures we took and write up an explanation of what was observed. The really neat thing was that he had a good time and really enjoyed himself. I’m not sure what he wants to be, someday; but something in the scientific or electronics field would not be so bad.

Tim, W3ATB and I took an extraordinary hike to Knox Mountain this afternoon. We walked along the brook enjoying the music and scenery of the spring day. I worked Italy, Spain, and Portugal. Tim worked Illinois and took some fantastic photos.

Barely a quarter of a mile from the pond we came around the corner and found a pile of rubble in the middle of the trail. “It’s a landslide!” said Tim right away. And it was. Tim estimates nearly 100 tons of the hillside (mostly clay) had slid down the hill… some of it reached the brook.

We crossed it easily, although we had mud covered shoes by the time we reached the other side.

It’s always a treat when the pond and cabin come into view after the hike.

The day was warm… perhaps 65F. The black flies have just started to appear, but they’re not biting yet. Tim tossed his line nearly 50 feet over the branch of the large cherry tree near the cabin. He pulled up a Par End Fed for 40 and 20 meters. I chose a smaller maple and used a 33 foot wire sloping toward the south. I was running the KX3 set up on 17 meters. Right away I worked IK2SND, Dan in Italy. Conditions weren’t great, but good enough for solid copy both ways. Meanwhile Tim was working K9MY, Jerald in Illinois with the HB-1B on 20 meters.

Next I worked ED5URL in Spain and CT7/RC2A in Portugal both on 17 meters. Then I switched to 15 meters and worked EA8NC, Manuel… again in Spain. I don’t think the propagation was very good because I didn’t hear many stations. And the ones I worked weren’t that strong.

Tim and I packed up and headed back down along the brook. It’s a day to be savored in memory. Blue skies, warm weather, a hike through some of the most beautiful country anywhere and some wonderful radio contacts… not just across the small pond at Knox Mountain… but across the Big Pond… all the way to another continent.

Not much special going on lately. Worked some SKCC members, spent some time on 6 meters and worked my first station over 3000 km there. My weather station always seems to be in need of repair and my website’s CMS needed upgrading. Oh yes, there is the daytime job, too. Busy, busy, busy.

But, my wife was so nice to bring me a 2.6 meter telescopic whip from one of her trips to China. And so, last Saturday afternoon, while my little girl was horseback riding, I took the KX3 and MP1 with the new whip for a spin. The longer whip proved okay, although now the loading coil is much too large. Without the coil the whip needs to be shortened to be resonant on 12 meters and lower. I made four QSOs: HL0HQ (the KARL HQ station), JD1BLY (from Ogasawara), 7M2ALZ and JL1NMB. The resident ostrich took interest in my setup and decided the counterpoise set was a nice toy to play with and so he took it from me. Who said QRP is not dangerous? Power levels may be low, but those beaks do have a lot of force in them.

Took a drive down to Superior WI yesterday May 3rd to take part in the A.R.A.C.  Swapfest in Superior Wisconsin. Got up at 5 am, picked up Wayne VA3WRL and Clarence VE3WCW and we proceeded for our 3.5 hour tour down the lake-shore. Stopped in Two Harbors for breakfast before heading into Duluth MN and then over the bridge to Superior. Had rain/drizzle from Thunder Bay to Two Harbors but was sunny after that. Arrived at the fairgrounds on Tower Ave. and went into the building to see what was on the tables for grabs. Lots of vintage radio gear, computer parts, hand helds, coax and almost anything that folks have been collecting in their garages that they wanted to get rid was there. There were having hourly draws as well for prizes. Had a chance to talk with lots of the folks that I have not seen in a while and the Thunder bay group had a good showing at the swapfest as well.

While this may not be a surprise to those with electrical engineering backgrounds, this is a first for me — never seen this sort of thing before. While the effect is very cool, it’s potentially very dangerous and you shouldn’t go jumping the fence at the neighborhood 50kW shortwave station to try it out.

Wikipedia on plasma speakers:

Plasma speakers are a form of loudspeaker which varies air pressure via a high-energy electrical plasma instead of a solid diaphragm. Connected to the output of an audio amplifier, plasma speakers vary the size of a plasma glow discharge, corona discharge or electric arc which then acts as a massless radiating element, creating the compression waves in air that listeners perceive as sound. The technique is an evolution of William Duddell‘s “singing arc” of 1900, and an innovation related to ion thruster spacecraft propulsion.

The effect takes advantage of two unique principles. Firstly, ionization of gases causes their electrical resistance to drop significantly, making them extremely efficient conductors, which allows them to vibrate sympathetically with magnetic fields. Secondly, the involved plasma, itself a field of ions, has a relatively negligible mass. Thus as current frequency varies, more-resistant air remains mechanically coupled with and is driven by vibration of the more conductive and essentially massless plasma, radiating a potentially ideal reproduction of the sound source.

After doing some looking around, I realize that I’ve seen a similar phenomenon in the past while visiting the Boston Museum of Science — the singing Tesla coil!  Here is a fun example:

Here’s a video by Dennis Blanchard, K1YPP who is also the author of “Three Hundred Zeros”

Dennis hiked the Appalachian Trail, among other places and has lived to tell us all about it.  If you haven’t read his book, then you’re missing a good read.  While there’s not a whole lot in devoted to Amatuer Radio, it is a good read nonetheless, and inspiring, too.
