SLAARC Field Day 2015

Here are 45 photos from the South Lyon Area Amateur Radio Club’s participation in the 2015 American Radio Relay League (ARRL) Field Day 24-hour operating event.

2015/06/28 (N) Field Day Teardown

I was up at 7:15 AM and showered.  The rain finally cleared out leaving blue skies but with scattered white clouds still blowing across the region on brisk winds out of the NNE.  Linda was up by 8 and got the fresh fruit ready for our breakfast cereal while I made the coffee, which we enjoyed in the living room to warmth of the natural gas fireplace.  I did not expect to be using the fireplace this time of year but we have the furnace turned off, and are still getting overnight lows in the 50’s, so the fireplace is an effective and charming way to alleviate the slight morning chill in the front of the house.

In spite of the weather the food tent stayed up and open for business.

I finished up the draft of my blog post for yesterday and started on this one while I drank my coffee.  By 9:45 AM I was ready to install the #6 green coated ground wire I bought last night.  I also decided to switch out the coax from the cable entry box (CEB) to the ham shack.  Linda had made a grocery list and left to do the shopping.

Outside I opened the CEB and disconnected the current VHF/UHF coax and let it slide back into the sump pump room (SPR).  Inside I removed the suspended ceiling tile in the northeast corner of the ham shack and routed the ground wire over the wall into the SPR.  I fed it through an existing cable tie on the bottom of one of the floor joists and through the outer wall into the CEB.  I had an unused copper ground lug and used it to connect the ground wire to the lower right mounting stud for the CEB copper backplane.

Back inside I uncoiled a length of 50 ohm coax that I borrowed from Mike (W8XH) and followed the same path as the ground wire.  Outside at the CEB I installed an N-male/SO-239(F) adapter onto the PL-259 connector on the end of the coax and attached it to the N-female socket on the lightning arrestor.  I was finished working in the CEB, closed the cover, and went back to the basement.

I decided to install the 36″ copper ground bar on the wall behind the ham shack desks just below the 120 VAC outlet strip, which required me to move the desks away from the wall.  I attached the end of the ground wire to one of the studs by spreading the strands and placing them under a washer and wing nut.  I need to get another copper lug to do this right.

I had a five foot length of braided tinned copper strap and used it to connect the ground terminal on the Go Box to the ground bar.  I spread the braid apart to make a small hole near each end, slipped the holes over the studs, and clamped them under washers.  This was a temporary arrangement for testing purposes.  I need to configure a length of #10 copper wire with a ring terminal on one end and a make spade connector on the other but did want to take the time to do that today.

With everything hooked up I called Mike (W8XH) to see if he was available for a quick radio test.  He was still at home and about to leave for the SLAARC Field Day site but gladly delayed his departure long enough to help me test the new configuration.  The result was a better send and receive signal on 2m, both direct and through the South Lyon K8VJ repeater, with an S3 received signal strength with the pre-amplifier turned on.  The direct signal was also a little better on the 440 MHz band but my received signal from the Novi repeater was still weak and noisy and my transmit signal was still not strong enough carry the repeater.

I had planned to leave around 11AM for the SLAARC Field Day site but wanted some lunch before I left.  I had just made a sandwich and was gathering up my equipment when Linda got back from her grocery shopping.  By the time I left it was past noon.

I was interested in our ham radio club’s participation in this year’s ARRL Field Day event but neither Linda nor I had had any need or desire to operate radios.  I worked all day Friday on the setup of the towers and antennas and helped a bit last night with the emergency teardown of the VHF/GOTA canopy.  The 24-hour Field Day operating window closed at 2 PM today but some of the teardown began before that time and I wanted to be there to help.

Some teardown was already underway when I arrived at the SLAARC Field Day site and lunch was also just being served, so everyone took a break to get something to eat except Steve (N8AR).  He was sitting in his car making contracts on the six meter (6m) band using the mobile radio in his car.  He had connected it to the 6m beam antenna on top of the big tower.  The 6m band is known as “the magic band” because it will suddenly “open” and allow very clear communication over great distances and then just as suddenly close.  It had apparently opened up this morning from the Mississippi River to the East Coast and south into the Caribbean.  One of our members made a contact with someone in the Dominican Republic.  While I was watching and listening I heard calls coming in from South Dakota and New Mexico.

This is the fourth year that Marianne Roney, the wife of one of club member Ed Roney (KD8OSM), has taken care of the Field Day meals, which include lunch and dinner on Saturday and breakfast and lunch on Sunday.  The meals are $5 per person per meal, which is a bargain for the variety and quantity of things she prepares and provides, except that there is typically very little we can eat.  She would make special provisions for us if we asked (she did the first year) but it is extra work for her and we are still left with not being able to eat most of what is available, so we do not purchase meals.

Operating stations are often staffed by two people, one operating the radio (left) and the other logging the contacts (right).

As the operating event was drawing to a close the computer in the 40m tent shut down.  The computers are not used to operate the radios, but are connected to them and are used to log the contacts using the N1MM Logger+ program.  The program reads key information about frequency and mode from the radio so all the logger has to capture are call sign, operating category, and section.  (Club member Larry, K8UT, is a member of the N1MM Logger development team.)  Every radio was paired with a laptop computer running this program, and the computers were all linked together via Wi-Fi.  As a result, the operators/loggers at each station could see all of the contacts that were being made regardless of which station made the contact and each computer contained a complete list of contacts.  The program also flags “dupes” (duplicate contacts).  In a contest situation this allows the operator to see that they have already worked that station on a particular band and mode and not spend time working it again on the same band and mode as duplicate contacts do not contribute to the contest score.

Just as it had started 24 hours earlier, at 2 PM it was all over without any fanfare.  The radios and computers were shut down and then the AC power generator was shut down.  Cords were unplugged, coiled, and staged near the vehicles they would eventually be loaded into.  Radios and computers were carefully disconnected, boxed (in some cases) and carried to the vehicles of their respective owners.  Tarps were pulled from the tents and folded and then the tents were collapsed and folded.  Four of use took down the 40m crossed dipole (inverted V) antenna and then took down the small support tower and disassembled it.  A larger crew eventually lowered the bigger tower, which required a winch, until it was resting in a step ladder.  This was necessary because of the two beam antennas at the top of the tower.  They removed the 6m and then the 20m beam antennas and then lowered the tower to the ground.  Part of the crew disassembled and packed the two beam antennas while the rest of them took the tower apart

We were essentially done with the teardown by 4 PM.  The teardown is always much faster than the setup and yet it was very relaxed and went very smoothly.  In spite of weather challenges all day Saturday and overnight into Sunday, and the disappointment of not having all of our stations on the air due to losing tents to the wind, we had a beautiful last day for the event and teardown.  Blue skies, white puffy clouds, cool temperatures, lighter breezes, and low humidity combined with a sufficient number of competent, helping hands, made for easier work for everyone.  The group stood around reflecting on the event and everyone was in a good mode, a sure sign that the 2015 ARRL Field Day had been a success for the South Lyon Area Amateur Radio Club.

I was the last one to pull out, right behind Steve who was towing a fully loaded enclosed trailer with a lot of the club’s equipment in it and on it.  We chatted via the South Lyon repeater on the drive home, our last radio work for the day.  I was home by 5 PM and just relaxed until dinnertime, tired from the sun, fresh air, and work.  For dinner Linda made a potato and spinach curry dish that she found in her Indian cookbook.  She also steamed some asparagus that she bought at the Howell Farmers Market this morning.  We had a quiet evening of reading, writing, and games before turning in at 10 PM.

 

 

2015/06/27 (S) ARRL Field Day

At 5 AM I was vaguely aware of the sound of rain.  The cats were chasing each other through the house so I got up to make sure nothing was amiss, such as another mouse.  They were just having a bout of morning friskiness.  I added a little food up to their bowls, which drew their attention, and went back to bed.

I finally woke up and got up about 8:15 AM and got dressed in a suitable manner for today’s American Radio Relay League (ARRL) Field Day event.  The temperature was in the mid-50s, overcast and raining with blustery winds; not exactly the nice summer day we were all hoping for.  Some of the members of the South Lyon Area Amateur Radio Club (SLAARC) were gathering for breakfast at the usual place (Senate Coney Island) at the usual time (8 AM) but we obviously did not join them today.

I went to my office to retrieve my Sony DSLR and decided to turn on our Icom IC-7000 ham radio.  I had it tuned to the SLAARC (K8VJ) repeater in South Lyon when Keith, KD8YYJ, announced his presence.  He was driving from the west side of Howell to Wixom and seeing what repeaters he could hit.  We chatted for 10 to 15 minutes and I invited him to stop by the SLAARC Field Day site at the South Lyon Township James F. Atchison Memorial Park.

I worked all day yesterday as part of the SLAARC Field Day setup crew.  There was more setup to do starting at 9 AM this morning but the setup mostly involved radios, computers, Wi-Fi networking, and power.  I was not in any humor to rush off into the clammy weather conditions, and Linda was up by this point, so we had breakfast.  She found some Silk brand ‘yogurt’ at Meijer’s last week so we had that.  It was OK.  It is a creamy style yogurt, which is not my preference, but it was tasty enough.  Bananas, cinnamon raisin bread, and juice rounded out the meal.  Linda even made the coffee.  I turned on the natural gas fireplace to ward off the chill in the living room where we lingered and enjoyed our morning brew.

I finally left for the Field Day site around 11 AM.  The operating event started at 2 PM but the first of four meals was lunch today at noon and I wanted to capture photos of the rest of the setup and the lunch event.  It was raining lightly when I arrived and continued to rain until I left at 2:15 PM.  In between arrival and departure I took some photos and helped out a little bit, but there were plenty of people there taking care of what needed to be done.

Mike (W8XH) brought his Icom IC-2820H dual band mobile radio and several lengths of 50 ohm coax and we transferred those to my car.  He then walked me through the various menus and functions his new Yaesu FTM-400DR/DE radio, a dual band (VHF/UHF) 50 Watt rig with digital voice capability and a color touch screen display.  A group of SLAARC members recently purchased a Yaesu DR-1X repeater that works with the new Yaesu digital voice and data modes in addition to the traditional FM mode and are testing it as a replacement for the current, and very old, K8VJ repeater.

Mike’s IC-2820H is available for $350 but the FTM-400DR has a $100 rebate through the end of June, bringing the price down to $500.  As much as I would like to have a VHF/UHF radio in my car I am looking at one of these radios to install in the cockpit of the bus so we can use it going down the road.  The long-term plan is to put the Icom IC-7000 HF/VHF/UHF radio in our towed vehicle and get the Hi-Q 80-6 antenna mounted and operational in addition to the Diamond SG-7900 VHF/UHF antenna that is already on the Honda Element.

For base station use I would like to get an Elecraft K3s or Flex SDR rig.  The K3s has become the rig of choice among the members of the SLAARC who are serious about working HF and contesting.  Either of those are radios that could be fairly easily moved from the house to the bus when we travel.  Antenna options in the bus could include running coax to the Hi-Q on the toad and/or a “flagpole” HF vertical that is mounted using the towbar receiver or a base stand that goes under one of the tires.  An antenna switch would allow the use of the VHF/UHF antenna that was already installed for the cockpit radio.  All of these “base station” options would obviously be for stationary use only.

I uncoiled the coax cables that Mike lent me to see how long they were.  There was a 5 foot piece that was too short for what I needed, and a piece that was approximately 40 feet, which was longer than I needed.  The third piece was at least as long as the 40 footer.  I “tagged” his coax with small white cable ties so I could identify them later and return them to him.

I did not want to mess around switching coax cables in the rain so I unboxed Mike’s Icom 2820 and got it set up to use with my existing antenna and transmission lines.  I spent a little time with the manual and then powered it up.  It was already configured from when Mike used it in his ham shack so I did not need to do any setup to use it.  I monitored both the South Lyon 2m and Novi 440 MHz repeaters and was able to “hear” both of them, although the South Lyon signal was much better (stronger, quieter, clearer) than the Novi.  A couple of SLAARC members were on the South Lyon repeater taking care of Field Day business.  I waited a suitable amount of time after they were done and called for Mike (W8XH) and he came back right away.

We repeated the testing we had done last night.  The performance with the 2m South Lyon repeater seemed to be much better but the performance on the 70cm Novi repeater was the same or worse with a fading component to the noise.  I think we were on the air 15 to 20 minutes.  Based on the test results from last night and this afternoon I think I have two separate issues that are probably interacting; the IC-7000 needs to be grounded and the 25 feet of coax from the cable entry box (CEB) to the radio (Go Box) needs to be shorter and much higher quality.  I need to install the ground bar on the wall behind the ham radio desks and then purchase a suitable length of ground wire and run it from the CEB to the copper ground bar.  I will also need to get a 15 foot length of 50 ohm LMR-400 coax from Scott (AC8IL) with an N-male connector on one end and a PL-259 connector on the other end.

Linda prepared our dinner at 5 PM.  She made corn-on-the-cob and “cowgirl steaks,” a new (to us) vegetable protein product she found at Meijer’s.  After dinner we drove back to the SLAARC Field Day site to socialize with club members at dinnertime.  The weather at our house was still rainy with light-to-moderate winds and occasional stronger gusts.  We arrived at the Field Day site to find a flurry of activity and strong, steady winds out of the north with continued sporadic rain.

The small red tent that was originally supposed to be the VHF tent was nowhere to be seen and at least eight people were engaged in trying to control and fold up the large canopy that the club purchased yesterday at Costco to serve as the combined VHF and GOTA tent.  We quickly learned that the small tent, which was not being used, had collapsed and the large tent, which was unoccupied but full of radios and computers, had come unstaked and blown over in the wind.  Those who were not helping with the equipment canopy were gathered in the food canopy.  I pitched in on the equipment canopy rescue and Linda took the camera and joined the folks in the food tent.

After gathering up all of the pieces of the canopy and getting them back in the trailer some of the team added extra ropes and stakes to the windward end of the food canopy and both the 20m and 40m tents.  Another part of the team, including me, got Marty’s (KB8JIU) satellite tracking equipment out of the screen room, which had been draped with solid plastic tarps to keep the rain out, and then took the room down, disassembled the legs, folded it up, and stuffed it in the trailer.  The red tent was stuffed under a picnic table that was in the screen room so I grabbed that and put it in the trailer.  The support pole for one end of our off-center-fed dipoles was bending over to the south more than we liked.  Steve, N8AR, tied a rope around the existing rope, which was inline with the antenna and being used to keep it taught.  He slid the second rope up the first one as far as he could get it to go and then pulled it out to the northwest (the antenna was oriented east-west with the tension rope running east off of the east end).  He pulled it out until the support pole was reasonably vertical and I staked it down.

The winds really howled out of the north driving the rain before them.  This shelter (from Costco) did not survive along with another tent and a screen room.

So the bad news was that some of our Field Day setup had not survived the weather which had not even reached severe conditions.  The good news was that our generator was still producing power, all of our towers and antennas were intact and functional, we had our two key stations on the air, and our food canopy was full of people and hot food.  Not the Field Day everyone had hoped for, but a great opportunity for teamwork and camaraderie and a learning experience to be sure, even if it was not the kind of lesson we wanted to learn.

We left around 7:30 PM and went to the New Hudson Lowe’s, which was very close to our Field Day site, where I bought 18 feet of AWG 6 stranded copper wire with a green sheath.  As soon as the weather improves I plan to run this from the CEB to the ham shack and use it to connect the ground bar in the shack to the copper backplane (ground plane) in the CEB.  I will then connect the ground on our Go Box (Icom IC-7000) to the ground bar and see if it helps with my noise issue.

Back at the house Linda wanted to watch an episode of NCIS Los Angeles, which we can now do thanks to our new OTA TV antenna.  We then watched an episode of Christina Cooks, Christina Perillo’s vegan cooking show from a decade ago.  These are still relevant and useful episodes and we especially enjoy them having seen and met her and her husband Robert on our two Taste of Health Holistic Holiday at Sea vegan cruises.  Linda read and I wrote for a while before lights out and off to sleep.

 

2015/06/26 (F) Field Day Setup

I was up at 7 AM and ready to leave for breakfast with the other SLAARC members who would be setting up our temporary field site for the ARRL Field Day event.  I called the SLAARC repeater and Steve (N8AR) came back and wanted to know if I had the site use permit from the township?  No, I did not.  Paul, N8BHT, got on the air and said he gave it to Linda so I went back home.  Linda was up but had no recollection of receiving it.  We looked through the materials she got from Paul but could not find it.  I left again for breakfast but after more radio QSO went back a second time to retrieve all of the records and bring them with me to the field day site.  (Our best guess is that he gave the permits to the other Linda (NF8C) who is the club secretary.

By this time it was too late to make it to breakfast so I stopped for coffee and fueled my car.  Mike (W8XH) also did not go to breakfast with the group in South Lyon so we were the first to arrive at the site.  Another 10 guys showed up shortly thereafter.  John’s Sanitation then arrived and dropped off our rented porta-potty.

We had 12 people for most of the day and 14 total who were there for at least part of the day.  It was a good group and just the right size for the task.  We worked steadily from 9 AM until almost 5 PM except for an early afternoon lunch break.  By the end of the day we had erected two towers and set up six antennas (20m beam and 6m beam co-located on the taller tower, two off-center fed dipoles from the taller tower, a 40m crossed dipole from the shorter tower, and a 40m 1/4 wave vertical with four elevated counterpoise wires).  We also put up three radio tents, a screen room, and the big food tent.

The weather was cloudy and dull and not the best for taking photographs but I took pictures anyway.  I had to be deliberate in my shot selections, however, as both of my memory cards were almost full.  All of the work that needed to be done today was finished by 4:30 PM and most of us took off.  Our Field Day chairman, Paul (KD8SNZ), and a new member, Ron, setup their tents as they would be spending the night and keeping an eye on the site.  Steve (N8AR) and Eric (K8ERS) stayed a bit longer to test the antennas using the mobile radio in Steve’s SUV.

Back home I took a nap for an hour before dinner.  Linda grilled Portobello mushrooms and corn on the cob and cut up some fresh strawberries and cantaloupe.  After dinner I went to my office and transferred all of our recent photographs from the Sony alpha 100 DSLR to my computer and then to our older NAS device which we had with us this past winter.  I then started backing up all of the photographs we had taken since December 2014 from the old NAS unit to the new one.  This involved a significant number of images, a lot of gigabytes of data, and took a bit of time.

Rather than sit around waiting for file transfers to finish I decided to turn on the Icom IC-7000 ham radio and see if I could figure out why I could not hear the Novi 440 repeater on Wednesday when we tested the antenna and coax installation.  I checked the Nifty guide for the Icom IC-7000 and, as Mike had suspected, I did not have the Tone Squelch frequency set correctly for the Novi repeater.  I changed the mode on the 440 MHz band from ‘Tone’ to ‘TSQL’ and then caIled Mike (W8XH) on the phone to see if he could help me do a radio check.  We spent about an hour going back and forth between the Novi and South Lyon repeaters.

With the correct settings I was able to work both repeaters although I had a lot of background noise (static).  I played with the noise reduction (NR) and pre-amplifier functions and both seemed to help.  Mike tried various combinations of power and simplex operation and we determined that the basic problem seemed to be a weak signal in both directions.  I am still suspicious of the fact that I do not have the Go Box grounded as I vaguely recall from three years ago having noise problems with this setup until I grounded the box, which is tied to the radio ground.

Mike was suspicious of the coax I used to go from the lightning arrestor to the radio but looked up the specifications on my Diamond X-50N antenna and suggested that an antenna with more gain might be in order.  We also discussed the location where I placed the antenna on the tower.  Although most of the antenna is above the tower it is on the northwest leg.  The two repeaters lie to the southeast so the tower may be ‘blocking’ some of the signal although that does not seem likely to me.  Of more concern to me is that I mounted the base of the antenna so that two of the three counterpoise (ground plane) rods are even with, and parallel to, two of the three topmost crossbars.  If anything is being blocked it is likely those as the crossbars are between the rods and the repeater locations.

Ed (KD8OSM) jumped in briefly to let us know that I also had a ‘hum’ that sounded like the 60 Hz power line frequency only higher pitched.  I have a small fan installed in the back of the Go Box so I hummed the same pitch as it was producing into the microphone and both Ed and Mike confirmed that this was the tone they were hearing.  The fan is audible, but not that loud, and was two feet behind the microphone so I would be surprised if it was picking up the fan noise.  It is possible that the fan is inducing the hum electrically, but I believe it is a DC fan, so that seems unlikely.  I do not have an AC line filter installed on the fan, or anywhere in the box, so that may be a next step.

The larger of the two towers is up and secured.  It has a 6m beam antenna on top of 20m beam antenna on a common mast with a rotator.  We also attached one end of an off-center-fed dipole to this tower.

We also attached one end of an off-center-fed dipole to this tower.  Tents are being erected to house the various operating stations.  The weather was overcast and forecast to get much worse before Field Day as over on Sunday.

Mike and I wrapped up our QSO and I shut the radio off.  I checked my e-mail and saw that the May 2015 issue of Bus Conversion Magazine was available.  I logged in to the website and downloaded both the standard and high definition versions of the April and May digital editions.  By the time I got to bed it was well after 11PM.  I finished up yesterday’s blog post draft and outlined as much of today’s post as I could before I lost the sequence and details of the day’s events.
