Kirk Showed pictures and discussed a recent business trip to Maui where he brought his amateur radio and the club’s buddipole antenna system.

 

We will have a trailer cleanup day on October 6 at 11:30 AM at the EOC trailer in the West Parking area of A6.

 

October 26 from 9AM to 11AM there will be a CERT exercise that needs Amateur Radio volunteers.  It looks like we need 5 people.   We need to select a simplex frequency to use.  147.510 on 2m, but we are thinking of picking one on 70cm to avoid interference with the security radios.

 

We discussed budget items, and it was put forth to get new VHF radios before next year’s field day.

 

We also discussed ways to get more people to come to the meetings, and we may have a raffle at the meetings in the future.

We had some discussion about the upcoming Field Day. We considered what we could do for a 20 or 40 meter wire beam antenna on top of the parking structure and how we would keep the driven element and the reflector parallel to each other. However, given that we expect very few people to be available to do Field Day with the club, we decided to just stick with the antennas we already have: the CrankIR and Buddipole for HF and the verticals attached to the fiberglass masts for UHF/VHF. We will probably run a 20 m station and either 40 or 15, depending on conditions that day.

On the Wednesday before Field Day, we will put up signs advising people to not park in the travel parking on the 4th floor and the North-East section of the 3rd floor. Cones and tape will be put out Thursday afternoon to block off parking spaces, and tables and chairs will be delivered to the 3rd floor Friday afternoon. All equipment will be moved Saturday morning. Kirk will bring 5 gallons of gas for the generator. We won’t invite any external visitors (like city council, press, etc.)

For general emergency use, we discussed having a 30 m APRS system that can send an email out in case of emergency. Ryan will spec out a system and report back. We will also want to be able to communicate with COS/Chantilly on voice, which can be set up over email via APRS.

Kirk brought up the point that during the A6 evacuation a couple months back, the security radios caused a lot of interference on our standard go-to 2 meter simplex frequency (147.51 MHz). He suggested trying a 440 simplex frequency. We would have to test to see how far we can get with 440 simplex. If there is someone with access to a real antenna, we might be able to relay messages.

It was recommended that we purchase the Yamaha CM500 headsets for the rigs in the trailer and for Field Day use.

Kirk reported that he had asked about putting an A6 shack in an electrical room on the second floor of A6. Maintenance people got upset about us using the electrical rooms in general. We will be cleaning to be sure that we are not blocking any electrical panels in any of our shacks in electrical rooms, especially in A2. Kirk is waiting for approval on the A6 shack but will put together a preliminary list including costs for budgeting purposes.

Joe wants to buy a good Software Defined Radio for the D8 shack.

Budgets are due in July so we should allocate/spend money now.

May 21, 2015 Meeting Minutes

Five members in attendance: Kirk Crawford KG6MTE, Donald Hall KK6DCX, Ryan Noguchi AI6DO, Phil Martzen KK6PSA, and Teresa Moore AG6OD

Discussed putting a current club inventory and a list of things that can be checked out by members on the web site. Ryan will work with Joe to categorize the D8 shack, including creating a block diagram of how everything is connected and directions on how to use various equipment.

Field Day: 1800 UTC Saturday to 2059 UTC Sunday = 11 am Saturday through 3 pm Sunday

We will use the trailer as a base again this year, and park it at VC1. This year’s goal is to stay longer and make more contacts than we did last year. Don will be our publicity chair and contact the Orbiter and or Aerospace photographer to cover the event, as well as consider external media and inviting distinguished guests. Ryan will bring over equipment from the D8 shack. Kirk and Teresa will work on logistics, including loading the trailer, bringing over equipment from the A2 shack (easy up, banner, antennas, etc.), moving the radios in the trailer so that they are far enough apart that a different person could work each station, coordinating signups, and getting folding tables and chairs for the event. Kirk will coordinate getting the trailer moved after 11 am on Friday.

  • Things that need to be done in preparation for Field Day:
  • load trailer
  • space out radios
  • install circuit board in KX3 (Kirk)
  • buy headphones
  • get permission from Security
  • buy tower
  • look into off-center fed multi-band dipole antenna
  • move solar system over to trailer
  • make sure batteries are charged
  • make sure we have enough extension cables/feed lines
  • order table/chairs to set up under easy up
  • masts for 3 VHF/UHF antennas and one HF antenna
  • guy lines for masts
  • check out mics
  • gasoline for generator

Plan for stations: 2m, 220, 440 in trailer, Kenwood HF rig in trailer, KX3 HF rig, Teresa’s Yaesu FT920

Kirk will bring laptop and logging software

Do we want to try a laptop for digital modes?

Everyone should bring snacks/drinks

Other upcoming events: HamCon in Torrance September 11-13

Minutes from April 30 Meeting

Radio club meeting 4-30-15

5 members in attendance:  Kirk Crawford, Don Hall, Ryan Noguchi, Jason Bayonne, and Teresa Moore

Antenna Test report:  Last week we set up the Crank IR and Buddipole antennas and got some experience with tuning them.  The Crank IR is pretty easy; the Buddipole has to be adjusted manually.  It took a while to figure out how to use the SWR meter in the trailer as it is not a design anyone was familiar with.  We heard a couple people on 20 and 15 meters, but the bands were not very active.  We did not make any contacts.  We plan to do another test on Wednesday, May 6.  Ryan volunteered to go to the D8 shack to see if he could hear us.

On May 19, the club will be manning a booth at the Aerospace Career Development Day.  Our plan is to set up the KX3 and the Buddipole and just see what we can hear, and talk to people about the club.  We have to be there between 11:30 and 1:30, and will probably have to be there early to set up.  We need volunteers to help with the booth.  You don’t have to stay the whole time.

Pain, cheapest price for levitra http://amerikabulteni.com/2014/04/14/2014-pulitzer-prize-winners-full-list/ weakness of the extremity, and loss of vision are not present in its herbal version.

It has become viagra ordination amerikabulteni.com a blessing for the individuals suffering from the pain of injury as depicted by physiotherapist Glasgow. There are some other problems that stop sans prescription viagra a man performing well during the time of intercourse. June 27-28 is Field Day.  We discussed some plans.  We will use the trailer rig, the KX3 + amp, and Teresa’s personal HF rig for three HF stations.  We can use the Buddipole, CrankIR, and a club dipole on Teresa’s portable mast for these stations.  We will need to either guy the antennas or use weight sacks to put on the tripod legs of the two club portable antennas.  Don volunteered to look into weight sacks.  For the VHF stations, Kirk found some better whips than the current little tiny ones on top of the trailer.  Jason and Kirk will move the trailer out of the tent so we can test these VHF whips.  We can move extension cables, the awning, and anything else we may need from the shacks and into the trailer before Field Day.  We will plan several lunchtime trailer events over the next couple months to get the trailer ready.  We need to space the VHF radios farther apart so there is room for multiple people to work them.  We can get extra points for advertising (put a notice in the newspaper, invite representatives to see our site, etc.).  If you are interested in volunteering to help with the advertising campaign, please contact Kirk.  

Don gave a report on the cross-band repeater project.  He has identified the Kenwood TMV71A 144/440 dual band radio as the best candidate.  The plan would be to mount it on a cart so it is portable and not necessarily tied to the trailer.  He will be doing more research on an antenna, portable mast, cart, and battery that can last at least 8 hours.  Next month he will have a list of parts/prices for us to consider.

Our ultimate goal is to be able to contact Colorado Springs and Chantilly from the trailer.  However, we’re not there yet.  As an interim measure, after Field Day we would like to set up a regular sched with the radio clubs at COS and Chantilly from the D8 shack.  If anyone wants to volunteer to lead that project, please contact Kirk.
