Last night I had a few minutes to operate, so I thought I would call CQ with my 20M Rock Mite. I did a little more than CQ however, as I wanted to know how the radio was getting out. First, I measured the output power. I had assumed 500 mw of output during my first QSO's with the radio but after measuring the output, it was closer to 300 mw. Secondly, I wanted to see where the radio was being heard using the Reverse Beacon Network, www.reversebeacon.net. If you've never played around with this, it is pretty cool. There is an entire network of skimmers out there that will post your frequency and callsign if you are copied calling CQ on CW.
So I called CQ with the beam pointed due north from my Boerne, TX QTH. Withing seconds the RBN spotted me calling CQ on the east coast and shortly thereafter on the west coast. Pretty cool. So clearly I was getting out fine with my 300mw. After a few CQ's, AB4QL, Barry in Alabama, called me. I swung the beam and he was a solid 559 running his KX-3. He gave me a 329, but he didn't seem to miss anything. The contact was just short of a rag chew but we had nice QSO.
After we signed with each other, I looked up Barry on QRZ.com and learned that his QTH was 820 miles from mine. At 300mw that comes out to 2,733 miles per watt. Any way you slice it, that's good mileage.

Tidbits From the QRP History Book
I've been reading, in small doses, "The History of QRP in the U.S., 1924 - 1960" by Adrian Weiss, W0RSP. So after reading about some of the beginnings of the QRP movement it is interesting to note in 1924, QST Technical Editor, Robert S. Kruse, 1XAM, went on the offensive in promoting low power operation. His methods however were a little different than might be tried today.
It seems that Kruse felt that American operators had become too enamored with high power operation and that the QRM and inefficiencies of high power operation were precluding the "grassroots" operator from even hearing DX stations. Weiss writes,
"QST continually derided the abuse of power among American amateurs by coining a long list of derogatory epithets for the high power types. Such names as "watt-hog", "ether buster", "tribe of ampere hounds", "ampere chaser", "thunder factory', "watt burner" and "most miles per gallon" flowed across the pages of QST, leaving little doubt as to the attitude of the QST staff, and presumably the ARRL, to combat the developing dependence upon brute power by American amateurs in place of the ideals embodied in the QRP Operator...."
In, December 1923, the very first QRP contest, The Station Efficiency Contest, was announced with this subtitle, "Miles Per Watt: An Argument For The Small Set and For Intelligence In Place of Brute Force" Weiss comments, "In other words, the use of low power was inextricably linked with intelligence and diametrically opposite to high power"
Further Kruse argued, "...what if his brute power does let him cover 4,000 miles, isn't he still inferior to the other man who handled his power correctly and went twice as far per watt?"
So there you have it, QRP operation = Intelligence.
Need we say more;-)
The book goes into much more detail about the attack on high power operation and rising credibility of the QRP operator in those early days. Interesting reading and entertaining as well.

Cool 12m SOTA contact
As we all know the high bands have been less than stellar during this solar cycle peak. I was reminded how busy 10m used to be during "real" solar cycle peaks of the past by a recent article on AE5X's blog. As I remember it you could hardly find a place to call CQ on the novice segment of the band. However, even at lesser solar flux values, the high bands can still produce a lot of fun.
The past Saturday I had a rare weekend with not much on the schedule so I was chasing SOTA summits among other things. It was a fun day on the radio and I worked several Europeans on 12m. Currently the SOTA program has a 12m challenge in place which encourages activity on this band and when open, provides some fairly long haul DX for these QRP summit operations. I wasn't operating QRP, I was using my FT5000 and my Log Periodic Antenna up about 50 ft, however there are always several summit to summit QSO's among the activators that are QRP both ways across the pond. However this wasn't the most fun of the day.
Around 0130z on Saturday evening a SOTA spot came up for VK3ZPF, Peter, on a Mt. St. Phillack in Victoria, Australia on 12m SSB. I swung the beam around, not expecting to hear a peep. I wouldn't be writing the article if that is how it ended;-) I could hear the CQ faintly, but there was deep QSB. Finally on the peak I called and he came right back. We exchanged reports I had him in the log. A few minutes later, Glenn, VK3YY, who was with Peter was calling and I worked him as well. Glenn sent me an email saying that he was using a 40m EFHW antenna through an Elecraft T1 tuner and an FT817. Pretty cool and on SSB as well.
This radio stuff is fun.

The Rock Mite and It Did
I wrote a short piece a few months back on a 40m RockMite that I bought and I couldn't make a QSO with. I entitled it the "Rock Mite and Then Again It Might Not". The stigma of not making a QSO has bothered me and I was in need of redemption. So as I was perusing EBay the other day and found a very nice 20M RockMite that was up for auction, I couldn't resist. Besides the enclosure matched my paddle. So when it arrived I sat it on the shelf until this evening. My goal was two fold, first make a QSO, but more importantly get 1,000 miles per watt. At 500mw output, I would only need a QSO of 500 miles to make it.
My 20M RockMite That Could
I connected my 10 element log periodic antenna to the radio, plugged in my matching paddle and away I went. I was beaming west and received an answer to my first CQ, but couldn't complete the QSO due to QSB. At least I am getting out!!! Being rock bound can be a little discouraging as I endured a relatively long QSO on my frequency, 14.059, before turning my beam north. Quickly W5BM, Dan, came back to me. We had a nice QSO, I received a 359 report and my next question, what was his QTH? Dan came back, Tulsa, Oklahoma, which is 442 miles from my QTH, drats, a few miles short. I then turned my beam west again and soon, WN7SIU came back to my call giving me a 449 report and quickly signing with me. I asked for his QTH....Sandy, UT. which is 1,300 miles from my QTH in Boerne, TX. 2,600 miles per watt. Alright!!! Mission accomplished.
So the RockMite is in good favor with me again. I like this radio stuff.

APRS On Your Phone
A lot has changed during my ham radio career since I was first licensed in 1989. The logging was manual, you received your DX news via a weekly newsletter that you actually received in the mail and packet was all the rage. Thanks to innovation of the ham radio community, now several technical generations later, we enjoy a very different hobby than we did in those days.
Periodically, I peruse the app store on my iPhone to see what new cool ham radio apps have been developed. I will admit it has been a while since I've done that so this is probably old news to many of you. As I scrolled through the apps I came across an APRS application for the iPhone. APRS (Automatic Packet Reporting System), developed by Bob Bruninga WB4APR, combines packet radio technology with GPS technology to allow you to transmit your coordinates to a digi-peater that then posts your position on the internet. This allows others to know your location for any number of reasons, i.e., to follow progress up a mountain or simply for others to know that you are safe and to follow your progress to your destination. However, previously, to enjoy this functionality required a special radio with the GPS built in or a modification to add GPS functionality to your radio. However, with the apps now available you can accomplish the same thing with your iPhone. Of course you have to have cell service for the system to work and it can use up battery power, but the functionality can now be used without a radio.
So if you are a SOTA activator and have avoided the expense of getting a VHF APRS set-up, you can now accomplish the same thing with your phone. You can avoid battery degradation by only turning your phone on at intervals and allow the system to register your position, then turning it off again.
Very cool.

Back Home
No radio for me the last 8 days. I have been on a business trip to GW, G and EI. I did drive past a few SOTA summits, but unfortunately my business colleagues would not have understood. I did take a few pics of a side trip or two that I took to have a little fun.
Pembroke Castle in Wales
Guinness in Dublin
So now back to business at home and back to the radio to see what memories I can create with it.

A Little Prevention and a Pound of Cure
Its no secret that the amateur radio population is, on average, a little older than the current population's average age. That is a nice way of saying that we are older. With age many things accrue to us, wisdom, grandchildren, pensions and other good things. However there are some other things we tend to inherit as we get older that aren't so good including a few more health risks. We have a few extra pounds, our cholesterol goes up and we aren't in the same condition as we once were. We all know the story if we are more than 40 years old.
Recently, a very active SOTA activator who had probably 80 or 90 summits to his credit suffered a heart attack while on a climb. These events are always a little sobering because we aren't so different in age. It isn't intuitive that an active individual would be a heart attack candidate. The fact is he had 100% blockage in one of his arteries. My son is an MD and explained that the body will build it's own bypass system over time, so 100% blockage means that the main artery was blocked, but there were several smaller bypass blood vessels that were at least transporting some blood, but obviously in the case, not enough.
There were two lessons to learn from this incident. The first in the preventive part. After say, age 50, we should have a full blown physical at least every other year, complete with an EKG that will check you heart capacity and function. If you have to borrow money to pay for the physical, you should do it. A physical is not an expense, but an investment that will yield a nice return in the form of additional years to enjoy all the things you have worked for in your life. We should do some exercise at least 4 times a week, even if it's just walking for 30 minutes. If you aren't currently exercising, get the physical first and if you are exercising don't assume that you don't have issues. The example above should be enough evidence to convince you of that. One health issue associated with ham radio is that we can do it sitting down which isn't necessarily good from a health perspective.
The second lesson from this is the pound of cure. If you are involved in outdoor activities, hiking, biking, etc.. carry a small first aid kit and include aspirin in the kit. This will help to temporarily mitagate heart attack symptoms until help can arrive. Get a book on outdoor first aid and understand what you can do when you are miles away from help and have a medical emergency. There are even several apps available for your smart phone that give solid first aid advice.
The outcome of the incident above was a good as you could hope. His hiking buddy was calm and solicited help from other hikers, one of which had some aspirin in his pack. They had cell service and could call 911 and the victim was flown to a hospital where a stent was put in. (If no phone service, have a 2m rig with the local repeaters in the memory) He is much better and should be able to get back to climbing soon. His recovery is due, in no small part, to the alert reactions of those around him.
So go make that appointment.
