Last weekend was a contest in the park.

The setup at the park
Last weekend on Saturday the weather here was great lots of sunshine and very few clouds. So it was off the the park with the radio to give the ARCI welcome to QRP contest a go. Its a 3 hour contest from late morning to early afternoon. I setup my Elecraft K2 along with my mono band mobile whip antennas. The key I used was the Mini Palm paddle which works great and has a super feel to it. I found the bands to be in good shape but was not able to find many who were participating in the contest. In total I made 3 contacts contacts in 2.5 hours of operation. While operating I did hear W6/DL6AP/P who was operating in the SOTA at location CT-086....translation Strawberry peak in California. I was not able to contact W6/DL6AP/P but I did hear him in there. There was some other very attended State QSO party contests going on at the same time and were very well attended. So over all I did not strike it rich in the contest by any means...BUT.......I did pickup some bonus points for just being portable on battery power with a portable antenna.

QRPometer case….

Finished product

A few months ago I built and blogged about my  QRPometer build from the 4 state qrp club its a great kit. In the post there was only 2 con's that I could think of regarding the kit.
1.The TX and Antenna connections were RCA and not BNC, the kit now ships with the RCA to BNC      adapters.  
2. The meter did not come with a case and the rear of the meter had an exposed circuit board. I felt this left the meter vulnerable to damage.

My solution to problem number 2
first attempt....not good
We have in town a great electronics parts store it's been here for just a few years now but it's fantastic I don't have to travel for about 40 minutes to the next closest store. I ventured off to the store for a case, it was a plastic case I had in mind. The metal and or aluminum  cases I felt were just not as easy to work with for the needs I had. I brought the QRPometer with me to assure I got the right depth and width. I found a case that was deeper than I was wanting but it was all they had....so I purchased one.....that later turned out to be a mistake!!
New opening and front plate on
With the chosen Hammond 1594E box at home using my machinist ruler I traced the cutout on the box that was needed to house the meter. The best tool to cut the case I felt was the Dremel hand held rotary tool that I had....so I thought!! With my pencil lines all in place the Dremel was used to make the hole, I found I was so consumed with the cutting line that I did not notice the spinning chuck that held the cutting blade was destroying my plastic box. As Murphy's law would have it this problem was only noticed after all the cutting was done. The top cover was a mess and since I am a VERY fussy person this just would not due. So it was off to the electronics store for another box and to rethink the opening for the QRPometer. It was not until I got home the idea came to me to use my coping saw. There is more control with the coping saw and a neater cut would be the end result. I also came to the conclusion that a smaller opening would be smarter as well, less cutting and less chance for a mistake. With the revised hole cut with
Meter in the new case
the coping saw the QRPometer with some tweaking of the hole fit just right. As always another thought came to mind........the meters power comes from a 9 volt battery that is sandwiched between the QRPometer circuit boards. In the future this battery is going to have to be changed. I am not going to want to take 20 minutes of dis-assembly and assembly to change a battery!!!! As you all know batteries go dead at the most inopportune times. It was off AGAIN to the electronics store for a 9 volt battery holder. I found the perfect flush mount holder and to instal it meant  to just extend some battery leads off the QRPometer board and cut but another hole in the plastic box. This was a very fast addition to the QRPometer box and the coping saw again made short work of adding an opening to the side of the plastic box.

Lots going on….but no on air time.

No room for Oliver on the old desk
The new desk twice the size
The first half of August sure has been busy around the shack here, not busy with on air time but with getting things done. I have built the A A Engineering smart battery charger for my Elecraft K2. I will be posting the build in the near future. On this project for the first time the during the "smoke test" I actually had SMOKE!!! With kits I have found some of the final check out testing is what I call "destructive" testing as opposed to non destructive testing. Going to a destructive testing  with the Smart battery charger post. One of the kits I built just a short while ago was the QRPometer and it did not have a case...well it does now and that too is going to be another post. I am really not finished with that case yet. I was at the
electronics store the other day (picking up parts as a result of a destructive test going wrong) and saw a neat 9 volt battery holder I am going to add to the QRPometer case. I also have sold all of my items that were up for sale and I have the funds to order my Elecraft KX3. It's not going to be here until  October but that will give me time to read the manual and set up a place for the radio. While on that topic with some of my funds I went online to Ikea and purchased a much needed larger table for my kit building. The old desk was just way to small and things were falling off. The old table was actually a computer desk and it now is off to the side in my shack with an  iMac (27 inch screen) one that Julie donated to me!!! So the new Elecraft KX3 is going to run on Mac software.

F8DGY's antenna
The on air time has been very limited as having to get things done around the house and shack the rig really has not been turned on. I did manage to get some radio time in late last week in the evening. I heard clear as a bell Chris F8DGY calling CQ on 20m. I dropped the K3's power down to 500mW's and gave him a go. He came right back to me with a 579 report. It was a fast exchange and he was off answering others. For me that that a 7,597 miles per watt contact.

Double Dip Weekend August 2012

Homebrew Buddipole inspection

Homebrew Buddipole inspection

Great weekend of QRP Portable fun. Saturday our Central FL QRP group had some new ops join us and we had a good time comparing antennas and rig setups at Sylvan Lake Park in Sanford, FL. As is typical, we did more talking than operating but did manage to sneak a few qso’s in on 20 and 17 meters. The contesters in Europe were hot and heavy on 15 m too so made for a fun day despite the heat and high humidity. I was a bit disappointed to not be able to snag any fellow Polar Bear QRP ops on 30m but the band did not stay open long and the other stations were operating on alternative bands.

Sunday after church was the first annual NJQRP Skeeter Hunt.  So glad to work Skeeter Hunt promoter and fellow Polar Bear, Larry, W2LJ before the lightning ran me off. Larry was my last QSO of the day as a thunderstorm started making LOTS of noise and it was my signal to pull down the 31 ft Jackite and wire and get out from under the shade of the 50 ft tall pine trees down by the lake! YIKES… just made it too!

I ran my Sierra at 2.4 watts out into an end fed half wave suspended as a sloper from the 31 ft Jackite pole in a WNW direction. I normally use the trees to get a bit more height for my wire, but the Jackite goes up and down faster and with storms coming, I chose the simple and fast way to git ‘er done. Turned out to be a good choice. Band conditions were pretty good on 20m and I was hearing a good bit of activity. After 1800 the Caribbean, Central and South American SSB stations were causing a good bit of QRM down here in FL. They all seem to run power and gain antennas so we learn to listen through the chatter here in FL.  The approaching storm was obvious as QRN increased with distant lightning stirring up the noise and crashes. Nonetheless, the signals were pretty good despite the distractions and there were some SKCC, FISTS and other cw fans out there having fun too which made the band busy.

I built a simple key and am posting  a photo of my K4UPG Knee Cap Key. Used the lid of a bulk black peppercorn jar and made a simple non-iambic key with paper clips, standoff and a bit of wire. It actually worked fairly well, but not good enough to use for the whole contest. As a long time CPG (Contest Point Giver) I decided that was a good way to give myself some points so took advantage of the bonus points! It did inspire me to try a more substantial lid and make a strap to use it as a leg key for portable ops.

Umbrellas for the rig and the op!

 

 

It was fun to hear so many familiar calls and work a few of our fellow Polar Bear Ops who were out for the fun too. Sure appreciate the effort to put this event on the calendar and process the results. Thanks to the NJQRP group for the support of our niche in the hobby and to you Larry for the time you devote to contests, blogs and getting us all out and on the air.

Here’s my results before the storm drove me for cover:

The first annual skeeter contest….done!!

Packing up for the contest
I took part in the first annual Skeeter contest sponsored by the NJQRP club the first years theme was to go to  your favorate outdoor operating place and get involved with the contest. Well up this way the weather was not looking like it was going to co-operate. My fav place to operate was out in the open and very vulnerable to the weather....namely rain!! I decided to head out to a location that offered some trees as
The weather to look forward too
shelter just in case of a sprinkle, as for a down pour my car was beside me and the rest of the contest could be finished from there. I was using my Elecract K2 and this by the way this was the first contest  this rig has ever done as battery powered. My key was the Mini Palm Paddle which by the way worked great!! My antennas were mono band mobile whips on the back of my car. I operated QRP at 5 watts Oh and the K2's battery lasted for 4.5 hours at 5
watts with me calling CQ and not searching and pouncing.
The weather was a mixed bag from nice sunny skies (very rare) to very threatening overcast that did let go
The setup...with a bit of rare sunshine

with rain at times.Over the last month the temperatures have been in the upper 30's and low 40C...today it was nice and cool almost to the point of putting on a long sleeve shirt (which was used to cover the rig during light rain). The location I chose was about 15 minutes from my home and offered a pic-nick table, trees and what I consider a luxury when operating out and about a portable washroom!! The bands were busy with not only the Skeeter contest but the WAE contest as well. I did have some European stations involved in the WAE contest respond to my "CQ Buzz contest" Thats ok they gave me their report and serial and  I asked for their power output and then they moved on this made it a skeeter contact....I believe anyway???
Covering for rain drizzle
I confined my operating to 20m as it seemed to be a "buzz" with skeeters but at 14.060 for some time there was some SSB going on, not sure if anyone else heard it but they were there right on the CW QRP calling frequency. While calling CQ I did have someone come back to me at the same time a passer by asked me what I was doing and showed an interest in ham radio. So I sacrificed the contact for taking time to talk with this gentleman about the hobby. So if your reading this blog I was not ignoring you just had to promote the hobby.....:). I had to end the contest around 4:40 as the Elecract K2 was telling me that the battery is getting to the point of no return so it was time to shut things down.
When it really rained
I made in total 19 contacts including DJ5AV from Germany and YU2A from Serbia. 12 of  the contacts were fellow Skeeters as they had Skeeter numbers. One contact was just an average QRP op not in the contest but wanted to know what he had to give me as an exchange so he could count in the log. Over all I had a great time even though the weather was touch and go at times.
Finally...a must have!!!
See all you Skeeters next year!!!



Trail Radio

Ham radio and trail hiking have been a natural pair. There are a few hams (that I know of) who have stood out over the last few years in hitting the trails with their amateur radio gear.

The first is Ed, WA3WSJ. He has been out on the Appalachian Trail (or AT) numerous times and has brought along a minimalist setup to get on HF and make some contacts. Chances are that you have heard of the Appalachian Trail – it streches from Georgia to Maine and allows an individual to hike from start to finish.

Ed’s an advocate of pedestrian mobile (WA3WSJ/pm) and has published a few books that tells of his experiences and offers advice for those interested in following his footsteps. He also has established the Great Outdoor Radio Club, which offers resources to avid and aspiring radio trail men.

Another amateur radio hiker is Dennis, K1YPP. He actually completed the Apalachain Trail and also wrote a book on his expierences. Hiking from one end to the other involves reducing the backpack weight as much as possible. Dennis successfully used QRP rigs during his time on the trail.

Here is a podcast of two hams who discuss hiking the Appalacian Trail, including the use of amateur radio (ham radio) and QRP (low power, less than 5 watts) along the way. From the series at Atlanticon 2006 in Timonium, MD.

The APRS folks also are involved in activities on the Appalachian Trail (check out here and here).

Heading west, the next major trail is the Continential Divide Trail. The trail goes from Mexico to Canada and spends a good portion of its time following the Rocky Mountains. Although not a dedicated Continential Divide Trail hiker – Steve, WG0AT, has spent plenty of time in the Rocky Mountains making amateur radio contacts. Steve’s take on hiking is a bit different as he brings two goats with him that help carry the equipment. If you have not seen his Youtube videos, then you are missing out.

Bob, K0NR, is also active in the Rockies… having most recently participated in a unique ham radio event – The 14er. Paul, W0RW, is an pedestrian mobile ham who has taken to the mountains to log contacts. However, I do not think either Steve, Bob, or Paul have actively hiked the Continental Divide Trail along with their rigs.

Further west is the Pacific Crest Trail. I was curious to find that not many hams head to the Pacific Crest Trail for hiking and QRP work either. There is a repeater guide by Bill, AA6J – but I am not sure how much of the trail he has hiked or if he brought any HF gear. The only ham I can find that has attempted the hike was Bruce, N7RR. It also looks like he did not make it all the way. Being a Californian, I am surprised that more west coast hams have not hit the trail along with their HF radio gear.

Have you had a QSO with a ham on the Appalachian Trail, Continental Divide Trail, or Pacific Crest Trail?

How do you feel about the idea of packing up a rig and heading for the mountains?

Weekend happenings……..

During the NAQP CW contest
In Canada Monday is a civic holiday.....translation...LONG WEEKEND!!! The weather has been a mixed bag of sun, heat and thunderstorms with heavy rain storms. On Friday a package arrived for me from A&A Engineering. My Elecraft K2 is outfitted with the the internal rechargeable battery. A&A Engineering offers a great charger called a smart charger it's combo 1amp swithchable to .05amp charger. Of coarse I ordered it as a kit and I am looking forward to building it in the near future. So there will be more on the charger when the build happens this thing is great and can really extend the life of your rechargeable batteries.




On Saturday I took part in the NAQP CW contest. It was this day and mostly early evening and evening that the thunder and lightening storms came my way. This limited my on air time in the contest.  I entered as QRP at 5 watts and was going to lower the power into the mW range but the conditions would not allow it. I was having a hard enough time making contacts with 5 watts.

First time it has been blank
 The total points for the contest were 1,890 not a very high score at all but I was only in the contest for about 2.5 hours do to a late start, BBQ for dinner and the lightening  storms. The highlight to the contest was making contact with two Cuban station CO2JD and CO2MS who were taking part. 
 Another event was I did not take time to copy down call signs and exchange info on a pad of paper it was direct keyboard copy and type the info into the logging program. I have been practicing for months using PC contest practice software to get the keyboard and speed down. I was using the decoder on the K3 when the code speed was CRAZY.....but over all it was a success.        

 I decided to take the plunge and purchase the Elecraft KX3 my previous post talks about selling off gear for funds BUT the great news is all but two (very minor) items have been sold. I was able this afternoon to call Elecraft and place my order for the KX3. Along the radio the optioned I ordered were the KXFL3 dual-Passband Roofing Filter, KXAT3 Internal, 20-W Automatic Antenna Tuner, KXPD3 Precision Iambic Keyer Paddle and the KXBC3 Internal NiMH Charger with Real-Time Clock. The wait time for this rig is anywhere from 60 to 90 days. 
 So that is how the weekend more or less went here at VE3WDM!!
