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.

Field Day

Field Day Preparation Report

5/11/16 Field Day preparation

Kirk, Teresa, Ching, Bob

We finalized our location and will be setting up on top of the parking structure. Unless a lot more people express interest in coming we will not set up multiple locations this year.

Radios: We will be using the Kenwood and KX-3 HF radios and the three VHF/UHF radios from the trailer. We will use the two power supplies from the trailer, one for the two HF radios and the other for the three VHF/UHF radios.

Antennas/masts: For VHF, we have the multiband Comet CX-333 antenna (2m, 440 MHz, 220 MHz), a 2 m F23A vertical, a 220 MHz F142 vertical, and a 440 MHz beam with rotator in the trailer. There is a 440 vertical in a shack somewhere. We have 2 10’ masts in the trailer and a 5’ mast in the A2 shack.

For HF, we have the CrankIR for the Kenwood and the Buddipole for the KX-3 in the trailer. We plan to also build/buy a 40 m beam to be used with the Kenwood. We have 3 33’ masts that we can use for this, we need one more. We can use the light pole in the parking structure for the center mast.

As an aside, we also saw a 80/40/20/15/10 vertical in the A2 shack and plan to set that up as the HF antenna for the A2 shack.

Feed Lines: The Buddipole has its own long feed line. We found one 50’ and one 100’ feedline, but the 100’ line has the big N-type connectors.

Power: Need to make a power cable to go from the generator to the stations. The A2 shack has a 100’ 15A cable and a power strip. We’ll need extension cables and plug strips for each table.

Computers: Kirk will bring his laptop/software. Teresa may bring a laptop as well, in which case we would need to buy another copy of the software and figure out how to connect the two computers or log the results from two different computers.

LIST OF THINGS TO BUY

  • 4 headsets
  • 1 10-ft mast to strap to wall for VHF/UHF verticals. (We have a 5’ section in the A2 shack)
  • Gear for strapping masts to the parking structure wall (ratcheting nylon straps)
  • 3 50’ feedlines
  • 8 adaptors from N-type connector to normal RF connector
  • 30A/125 V NEMA L5-30 connector
  • 100’ of 30-A rated cable
  • Regular 30A/125 V connector for other end of generator cable
  • AC splitter
  • 2 100’ extension cords
  • 2 power strips
  • 40 m beam antenna (or everything to make one)
  • 500’ of rope + pulley (so we can use light pole in parking structure as the center mast for the 40m beam)
  • One more 33’ mast for the fourth end support for the 40-m beam
  • 4 large pipe clamps
  • 4 3’ sections of pipe
  • Whatever is needed for the KX-3/Buddipole setup
  • 3 lamps for the tables
  • Possibly another copy of the software (if we have multiple laptops)

LIST OF THINGS TO DO

  • Order 3 tables and 8 chairs from facilities
  • Have security cordon off parts of the parking structure (ideally by 11 am on Friday so we can start setting up Friday)
  • Make adaptors to hook KX-3 to power supply
  • Figure out what the various unmarked antennas in the A2 shack are and mark them
  • Move canopy in A2 shack to trailer
  • * Figure out how to log results from two computers

Repeater Status: WB6VMV repeater is fixed, just needs to be connected to the controller, which will happen 4/29/16. We will keep the net on W6HA for Monday and then switch back to WB6VMV on Tuesday May 3.

Field Day: the El Segundo gate is now closed on weekends, so VC1 is not an available location for Field Day. We can use VC2 and/or the parking structure. In the parking structure, we can use pipe clamps or big nylon straps to attach antennas to the wall. At VC2, the trailer would be parked to the north of the building. If only a few people plan to come to Field Day, we will not set up at two locations. The final location(s) will be determined at the next meeting.

Everyone that is bringing personal gear to Field Day should get it ready. Be sure to bring a self-contained system (except for power, which we will provide from the generator.)

Teresa will run the Kenwood HF rig and Kirk will be in charge of the KX3. We may want to set up a 40-m beam.

On May 11 at 11:30 we will meet at the trailer to do an inventory of the five rigs that will be used on Field Day. Then we will make a list of things to purchase before Field Day.

A2 shack: Bob Lanahan was designated at the new custodian for this shack and tasked with inventorying what is there and determining if we need to purchase anything.

Budget: We have $8K in the bank.

Ideas for spending money included:

  • Create an A6 shack
  • Upgrade D8 shack
  • Waterfall display dongles (3) with upconverter
  • Heil headphone sets (5)
  • New microphone for Kenwood
  • Portable tower w/ 20 meter beam so we can hit COS/Chantilly after a big earthquake
