 We’re at it again! Before the August 17 meeting, we invaded the large parking lot we use as an antenna test range once again. This time, we brought UHF antennas, and found that despite their smaller size, they were all very efficient. Don KB3LES brought his double diamond array, which may be small, but packed a big punch! Lars KB3WBT ran his Quagi through its paces, and Joe W3BC made reference measurements of his Rover Yagi.
The antennas all performed so well it was too close to call. Don’s antenna had high gain, and it was in almost all directions, Lars’ quagi had deeper side nulls, but was still “lobey” off the back. Joe’s Rover antenna had plenty of forward gain, but when as little as 15 degrees off the target, the signals went away and stayed away.
Don’s antenna had the smallest turning radius, and its wide beamwidth and high gain is perfect for net and repeater operations. It would be particularly well-suited to talking to mobiles, since its wide-pattern coverage would blanket an area better than any other antenna we tested. Plus it was the most unique looking of the bunch! Lars’ quagi was very lightweight being made of PVC pipe, and was easily portable. It would make a great antenna for working distant repeaters. Joe’s Rover antenna was showing the effects of bouncing down hundreds of miles of back roads on countless contest roving missions. A couple of the elements were loose, and could be heard and seen on the receiver as they flopped around in the breeze. It certainly meets its design requirement of hearing only what it’s pointed at, and rejecting strong contest QRM from off the sides and back. Mechanically though, it needs some maintenance before it falls apart, and perhaps a sturdier redesign to keep the elements where they belong.
 The exercise could be called a “quest for truth” and there were many truths revealed, even by the simplistic testing methodology we used. Given more time, and more attention to little details, some very accurate results could be obtained, but in our assembly-line session, we learned a lot, and got a good idea of the performance of each antenna under test. We will add these techniques to our inventory, and we’ll certainly be doing more antenna testing in the future.
After we ran out of UHF antennas, we switched the remote transmitter to VHF, and tested Lars’ latest creation—a 5 element two meter antenna that uses metal arrow shafts for elements. It is a clean-looking antenna, and initial test results showed it to have good gain and a very smooth pattern. After twirling it around the compass and recording received signal strengths, we gave it a real test—we dialed up a distant beacon and pointed the antenna its way.
Sure enough we heard a carrier, and then the CW id of WA1ZMS on 144.285 MHz, located on a 4200 foot mountaintop in Virginia, some 253 miles to the south!
 The net result was that all the antennas were winners! Every one of them had plenty of gain to pick up the weakest signals, while the off-axis signal sensitivity or rejection differed, making each antenna suitable for a different purpose. That diversity is what makes Amateur Radio so much fun, and gives us choices to meet our operating needs.
Not to mention that everyone there had a lot of fun!
 Congratulations to Herb Murray, W3TM for taking First Place Rover-Limited in the WPA section in the ARRL June VHF contest. With the help of W3BC, the team made VHF contacts in 54 grids all over the US, from 5 different locations. A lot of hard work and cooperation paid off nicely for the intrepid adventurers as they turned the beams and eked out the weakest signals to successfully make contacts hundreds of miles away on VHF and UHF.
“Band conditions weren’t the greatest,” acknowledges Herb, but the team made the most of it with 109 QSOs, 54 grids worked + 5 grids activated, for a total of 7,257 points. “Since W3SO was having technical difficulties, I said, “Let’s go roving!'” continued Herb.
Working stations hundreds of miles away is a challenge at VHF and UHF frequencies, which are usually used for local communications within a “line of sight” distance. DuringVHF contests and other VHF activities, hams routinely stretch the distance to several hundred miles, far beyond line of sight. Making these long-distance contacts requires sensitive receivers, high-gain antennas, and lots of operating skill. Hams are up to that kind of challenge!
Antenna range, that is… The Quad-County ARC held its first-ever antenna shootout preceding the July meeting. Using a low-power transmitter located almost 1/4 mile away, the group of antenna experimenters set up a monitoring position in a large parking lot adjacent to the meeting room on the Penn State DuBois Campus and took signal strength measurements of various 2-meter antennas that they brought for the occasion. The winner was a homebrew contraption made by Lars SM7FYW/KB3WBT.
Larry KB3YJH placed his home-made groundplane atop the test mast and the measured signal strength was good enough to take second place. Lars and Don KB3LES each tested several antennas and found the truth about directivity and gain.
After the meeting Joe W3BC presented a program on computer modeling of antennas. The highlight of the presentation was to input the dimensions of Lars’ blue ribbon winner, and see if it was supposed to work in theory. The answer was surprisingly close to the pattern measured on the test range, with deep side nulls predicted just like those measured on the range, and a fairly large lobe off the back of the antenna, again in accordance with the actual measurements.
It was so much fun, that another shootout is planned for 6:30 August 17th, before the meeting at 7:30. This second shootout will also be for UHF antennas.
 Don KB3LES will be bringing his secret weapon, which looks like something from NASA… You’ll have to be there to catch all the fun!!!
 On Saturday, June 2, 15 QCARC members and guests set up a demonstration station and and gave a public exhibition of foxhunting at the American Red Cross PA Heartland Chapter’s “First Bash of Summer” carnival in the DuBois City Park. Don Jewell KB3LES was the project leader, and provided the HF radio, VHF/UHF J-Pole, antenna analyzer, hardware and know-how. The Punxsutawney Area Amateur Radio Club provided the tent, which turned out to be very much needed when Mother Nature showed everyone who was boss.
Jeff Rowles KA3FHV held down the fort on the HF rig, and the HF antenna system built by Joe W3BC was given a thorough workout. The results were good, and Jeff reported that he was able to work every station he heard. The entire operation was set up in under an hour and it was great to see so many hands make light work of all the heavy lifting. In a Quad-County first, at no time did anyone discover they had left something important at home!
 Joe Rouse K3JLR drove in from Strattanville and brought Deirdre and Magi who gave us a special treat: Homemade Ham Radio cookies!
 Technology Specialist Lars KB3WBT/SM7FYW led several teams on foxhunts, and fielded questions from curious fairgoers. There seems to be a growing interest in foxhunting locally, and it’s a great opportunity to show the public another side of Amateur Radio they probably didn’t know existed. It’s an activity for the whole family, and participants don’t even need a license to have some ham radio fun!
Jefferson County ARES EC Kevin Snyder KA3YCB, along with assistant EC and Punxsutawney Area Amateur Radio Club President Steve Waltman KB3FPN were both on hand to help out and take part in the activities. Kevin also serves as the Quad-County ARC Public Service Officer, and brought portable tables and chairs for the event. Red Cross Liaison Greg Donahue KB3WKD made sure we had everything we needed, and connected us to the electrical power system for the duration. He also set up PA announcements directing fairgoers to our location.
Before the rainstorm hit, we discussed how much fun it was, and our desire to do more events like these. We look forward to the next events: Field Day, Race Day, Car Show, and Baker Trail Marathon.

We finally stopped talking about it and just did it! Before the April meeting, several members tried their hand at finding W3BC’s hidden UV-3R somewhere on the Penn State DuBois campus. Lars KB3WBT brought his DF tape-measure antenna, and Don KB3LES brought one of his home-built log-periodic antennas with his UV-3R for a receiver.  Ed and Don close in on the fox, as passing drivers gape in wonder... Stomping around the campus with antennas, the hidden transmitter turned out to be harder to find than expected. Lars reported the signal level picked up INSIDE the Swift building, and Don couldn’t get a good direction as he got closer to the fox.
The “winner” of the first heat was… Ed KB3VWX, who found it without using either a radio or antenna! We’ll have to call him “Eagle Eyes” from now on! Don took some time to introduce Bev W3BEV to the art of foxhunting before heading out to find the fox.
The first to find the fox using proper radio and antenna technique was Don KB3LES. After finding it, he got to silence it, and hide it in a second location. That second location was even harder than the first, utilizing a brick wall, a large flower pot, a metal trash can and a pile of leaves to hide out from the DF antennas. Lars was zeroing in on it when time ran out. Ed “Eagle Eyes” KB3VWX retrieved the radio and we all went inside for the meeting.
Reports were all positive, and some areas for improvement were discussed, notably signal attenuation when close to the fox. Others remarked that passing drivers gave us some astonished looks as we marched around campus with “space antennas!”
Everyone thought it was a lot of fun, and we look forward to perfecting our setups to do it again next month.

 Hello all readers, this is the Swede again.
This time I have been playing with a piece of pvc pipe and some aluminum wire, the result became a cheap and simple antenna for 70cm.
The pvc pipe is about 57″ end to end and is 5/8 diameter (you can use bigger, if thats in your junkbox) and then a couple of short pieces about 1/2″ used for the reflector and also the driven element. I also got a T pipe, as a “mastclamp” since the antenna only weighs a few ounzes ;)
Here are the element lengths: Reflector loop 28″ Driven loop 26 5/8″ Directors 11 3/4″ to 11 7/16″ in 1/16 steps….
Element spacing: R-DE 7″ DE-D1 5 1/4″ D1-D2 11″ D2-D3 5,85″ D3-D4 8,73″ D4-D5 8,73″ D5-D6 8,73″
I will bring it to the meeting, so if you have any questions, I’ll be more than happy to answer them.
Lars KB3WBT
 The big brother of the Baofeng UV-3R micro-HT is now available for a few dollars more. The UV-5R has a numeric keypad for entering frequency and DTMF tones, 128 memory channels, and 5 watts output power. It features a true drop-in charger, and a 7.4v 1800mAH (13.3 WH) Li-ion battery pack. The dot-matrix, alphanumeric display features tri-color LED backlighting, and the keypad has backlighting as well for night operation. See the article in the April Parasitic Emission for a review.
 The group price is $60, and shipments are arriving within a week of ordering.
I am looking into sourcing for extra battery packs. The best pricing I can get is $16 each with approximately two week shipping time. This situation should quickly improve, as this is a brand-new model that was just released this month. So far in our area, 10 have been purchased. They sound great on the air, and no complaints have been registered! This radio is every bit as good and in many ways superior to its nearest competitor, the Wouxung dual-band HT and only costs half the price!

Here’s a schematic for building a serial programming interface: 
 The Quad-County Amateur Radio Club 70 Cm net debuted Sunday April 1 five minutes after the conclusion of the QCARC 2 meter net. 12 stations checked in.
We will do this again on Sunday, April 8th. Please consider joining us. We will be using the K3EDD repeater on 444.625. The purpose of the net is to familiarize area amateurs with the characteristics and capabilities of the 70 Cm band. So circle your calendar and prepare to join in!
You might be surprised to see how well UHF works with today’s equipment!
SUSPENDED AT REQUEST OF 444.625 REPEATER OWNER
RESUMED June 3 on 443.475 N5NWC Repeater
 NEW Baofeng UV-3R Dual-Band HT I will be ordering 5-unit lots of Baofeng UV-3R HTs from China as orders come in. The cost is $46.00 per radio, shipped. I will program them with all the local ham radio frequencies of interest free of charge. (If you prefer to do it yourself, here’s the file: QC-Ham)
I can also obtain spare batteries at $3.95 each. Better deal: I found a supplier of 1800 mAH batteries for $4.00 each, which gives 20% longer battery life for a nickel more!!!
These prices are for 5 units or more, so orders will be held until I get at least 5.
Please note, these are the improved “Mark II” version with the dual frequency display and 19 menu functions. Color (red, blue, yellow or camo) units are $49.00 each and take longer to ship (two weeks). The regular ones take a few days. The first group order was for 8, I expect them to be here in time for the Meeting Friday.
Kevin W3PIG made a very nice ecomm box. Here are some photos.
 
Great Job!!!
TTHE BIG DAY is here! All the planning and preparation comes together today at the Old Town Sportsmen’s Pavilion on the Clearfield County Fairgrounds. This morning, we are setting up antennas and radios and computers, and the grill… and everything else!
The contest portion begins at 2:00 pm and ends Sunday at 2:00 pm. Help will be needed to tear down as well, so please stop by. Many hands make light work, you know!
The Public and media are invited, and this year we’re trying something new – a GOTA station. If you don’t know what that is, it’s a “Get On The Air” station to allow unlicensed people, new hams and old-timers who haven’t been active lately to make some contacts at a more leisurely pace.
We are there now, come on over!!!
Update Saturday 10:00 pm
Channel 6 News visited our Field Day site and depending on the other stories (of course) plans on airing their coverage of us tonight on the 11:00 news. Catch us tonight, and stop by in person Sunday after 10 am. The contest period ends for us at 2 pm, but we’ll be cleaning up and enjoying a hotdog and conversing with old friends for hours after that!
