First, a definition: Amateur radio, also known as "Ham" radio, is a radio electronics hobby (now including computers!) that's enjoyed by over a million people worldwide. Of these, a few hundred thousand are located in the United State where we often call ourselves "Ham operators" or simply "Hams." I'm not sure where the term "Ham" comes from but it probably has something to do with being on the air or "Hamming it up" in front of an audience - it's just my guess though because I've heard all kinds of explanations over the years...
 
Anyway, to become an amateur radio operator, or Ham, you must first pass an examination. The American Radio Relay League, here in the United States, can be contacted for all kinds of licensing and testing information at www.arrl.org. Ham operators use all kinds of equipment, antennas, and communications modes (FM, Single Sideband, Morse code, teletype, television, etc.) on a variety of frequencies throughout the radio spectrum. In addition to the millions of different frequencies at our disposal, we ham operators also use repeaters, our own satellites (see AMSAT), lasers, computer networks, and just about anything else that's available to experiment with!

QRP, In Amateur "Ham" Radio, means to voluntarily limit your transmitter's output power to 5 watts or less. In a world of 50,000 watt AM broadcast stations and 1,000,000-watt digital TV transmitters why would anyone want to actually reduce their power output?

Well, for me, I reduce my power output nearly all of the time for the pure joy of it! Turning my power down adds to the challenge and requires a lot more skill, on both ends of the QSO (communications), to get the same results as those operators who run a lot more power. Also, I believe the idea of QRP is in keeping with an environmental ethic that helps reduce the already too heavy burden most of us are placing on mother Earth and her resources. If we all attempt a lot of simple things, to reduce the load a bit, a whole lot of benefit can be achieved that will improve the quality of life for not only us, but all of humankind in general! Oh, also, there is always a bit of a health risk when you're around any kind of radiation - that not only includes nuclear reactors and X-ray machines but radio waves and cell phones (I talk a lot about cellphone radiation on my Antennas page...). So, turning down your transmitter's power output is a good safety precaution even though amateur radio transmissions are nothing compared to a cellular tower or TV transmitter!

Finally, most people engaged in QRP seem, to me, to be more "in tune" with the experimenting and a sense of inquiry that was the foundation of amateur radio in its beginning (remember, back when radio was getting "off the ground," in the early 20th century, prefabricated store-bought equipment was unheard of!). That doesn't make low power operators any better or worse than anyone else - it just means they usually seem to have a greater sense of adventure and an interest in experimentation!

Anyway, as time permits I'll devote more time and space (on this page) to all things QRP!

72s!

72 From Colorado "72" is a form of radio shorthand that roughly translates as meaning "Best wishes QRP!" This is a scan from page 36 of the May, 1996 Low Down newsletter published by the Colorado QRP Club. I believe I took the photo, sometime earlier that year, while northbound on Highway 93 between Golden and Boulder, Colorado...

 

In 2015 I had the pleasure of accompanying the Kaul/Mitchler expedition for the first ascent up Agrigan Island in the Commonwealth of the Northern Marian Islands. In addition to the six climbers, there were five guys on the machete crew and another half dozen or so folks associated with the boat crew, Guam PBS, and Saipan radio station KKMP. Me, K3TM, and KD8USU (ROger and Clint Kaul, respectively) made up half the climbing team and brought along various two meter hand-helds and the KX3 transceiver you see in this video. WIth a somewhat limited time for operating we were were able to make a number of 15 meter CW contacts in addition to completing a number three-way two meter QSOs near the summit and crater rim. Amateur radio certainly added to our island adventure!

40 Meter Transmitter Strip, WB0JNR - 1975 In January '75, shortly before going on active duty in the Coast Coast (I was still a teenager), I was trying to finish-up some QRP projets. This first photo is of a 40 meter transmitter strip that I was working on - notice the crystal and then the heat sink on the output transistor! Also, back then, I was fond of aligator clips and test leads for faster swaps between projects - even the Vibroplex was clipped into the circuit that way! In this photo you can also see the Ten Tec keyer and simple VOM I was using at the time.

Low Power Long Distance Record:

According to Rich Arland, K7YHA (Now K7SZ), in World Radio Magazine (February 1990, Year 19, Issue 8, pp. 46-47) the long-distance low power record is held by KL7YU and W7BVV using one microwatt over a 1,650 mile Ten Meter path between Alaska and Oregon in 1970. This is the equivalent of 1.6 BILLION Miles per watt!!

It's interesting to note that NASA's deep space missions typically achieve miles-per-watt ratings of over 500 million miles.  One example was the 8-watt signal from Pioneer 10*.  At a power level equal to that of a night light, the craft's signal traveled 11 billion km (6.8 billion miles) to Earth for a rating of 850 million miles per watt, or about half the KL7YU/W7BVV record...

*Launched on March 2, 1972 from Cape Kennedy aboard an Atlas Centaur rocket for a two-year mission to Jupiter.  The probe is now about twice as far from the Sun as Pluto.  At 13 km/s (28,000 miles per hour) it's heading in the general direction of the first magnitude star Aldebaran.

ARRL Field Day

ARRL Field Day Each year the American Radio Relay League (ARRL) hosts amateur radio's most popular on-the-air event in the US and Canada. On the fourth weekend of June, more than 35,000 radio amateurs gather with their clubs, groups or simply with friends to operate from remote locations. Many participate for the fun of it while others do it as means to test their equipment and hone their skills for emergency preparedness. Whatever the reason, there's no doubt that Field Day is the most fun you can have on a June weekend - I look forward to it each year!
