San Antonio Hams

In a recent posting by W2IK, the upcoming drill on Saturday, August 29th, was discussed in rather general terms.   Since that time, we’ve increased the scope of this event somewhat.    We’ve added one ARES group (Hayes / Caldwell County) to the mix, and have room for more if other groups want to  participate.

The event will only last 3 hours of radio time (11am – 2pm Saturday), compressing several days into 3 hours.  What fun!   We’ll be using local VHF freqs for operations near SA and another freq for local CC comm, plus a 40 meters net for the group, and MARS’s HF freq for their internal operations.  We’ll be using the NWS office in New Braunfels KD5UMW and Drisocoll Childrens Hospital W5DCH as net controls.

Event:  Hurricane “Albert” is expected to make landfall just north of Corpus with maximum winds at 130 mph.

• Hour 1 – Pre-Landfall – evacuation of residents in coastal cities in path of storm. Problems with evac routes and major side routes.  Status of Shelter fill rates, etc.
• Hour 2 – Landfall – Loss of power, high winds, property damage noticed, major flooding and high surf conditions.  Problems with evac routes and major side routes.  Status of Shelter fill rates, etc.
• Hour 3 – Post-Landfall – Sending in teams to evaluate damage, return residents, status of evac routes being returned to normal use, power failures in area, comm failures in area due to towers blown or power failures, etc.  Wrap up.

The Bexar Operators Group (W5BOG) is in the final stages of acquiring a 1994 Chevy Van/Bus for their use as a general communications and/or emergency communications vehicle. This 18 passenger bus will be converted into a go-anywhere communications van which will also be used for casual outings and “in the field” communications experiments. This “green” bus runs on propane. It will be fitted with complete VHF and HF  operating areas, propane stove, sleeping accommodations and “bathroom”. Special antennas will be used and a portable generator and solar panels will supply energy.    It is hoped to have the vehicle “up and ready” in a few weeks.

Never know who is going to stop by. In March, I had President Bush chatting with me. In May, I met all of the San Antonio Spurs and they gave me an autographed basketball. This Friday (07/24) some of the “Hooter’s Calendar Girls” stopped by my place of work and served the wounded warriors chicken wings and autographed calendars. All I got was this picture.

It’s a tough job, but someone’s got to do it.

Used my emergency go-kit today to run net control for the Small Texan Triathlon up in Boerne, TX. 

I took the photo (on right) while standing on the back ramp of the race director’s trailer used for running net control during this event.  I’ll post a separate blog entry with my photos from today’s event.  We were on the air from 7am until about 12:30pm for the event that had 137 entries.  1480 meter swim, 45k bike ride, 10k run, certified course.  Temp only got up to the low 90’s by the time we shut down net control, but we also had a fine light breeze, enough to keep us cool inside the trailer, but not strong enough to bother the athletes.

Using this go-kit with the bigger external antenna wWas perhaps a bit “over-kill” in terms of my actual needs since the 2 meter repeater we used was full scale on an HT antenna, but as I told one of the other hams, the big antenna in the air and the rolling toolbox with radios looks more impressive to the (non-ham) event organizers or other spectators.  I was able to charge 2 of my HT batteries using the DC-AC 300w power converter just to do it.  Didn’t actually need the extra batteries or HT’s charged, but I wanted a real life test.

The Bexar Operators Group has closed the availability of our late October, three  day “Jump Team Boot Camp” session as we have reached both our limits of registered applicants and  filled a short standby list.

I did turn away a few people, such as a father and son team from the mid-west who wanted to “audit” (just watch) the event. This boot camp is only for the “doer” and all participants are expected to do everything so they can be prepared for any real emergency event.

Some slots were filled by hams from North Texas, Army MARS and hams from the mid-west. There were no hams from South Texas who wanted to attend. I may have to make some minor adjustments to the timing of the event in order to accommodate people coming in from out of state and so the personnel teaching survival skills can be available. 

I probably will have a few of the special 200+ page session guides available after the event, replete with any additions made during the event, for sale to others.

This morning I met Bob W2IK up on the north side of San Antonio at a county park named Bullis Park. This is near Blanco Rd & Borgfield Road, on the back side of Camp Bullis (way outside Loop 1604). The purpose of this meet was to test some of Bob’s new antenna deployment ideas in preparation for the CQ VHF Contest next weekend. He had just received a new aluminum flag pole that would extend from 6′ to 25′ tall in 5 sections.

Bob rigged a mount in the bed of his truck, using an old heavy-duty umbrella stand (emphasis on the “heavy” part of that description) that he had rescued a couple of years ago at a yard sale or side of the road (I forget which), strapped the mounting pipe to that stand, inserted the flag pole, attached the yagi 2 meter beam antenna and coax, then raised it up to the full height. The pole itself only weighs about 10 pounds. He bought it on eBay for about $80 including shipping.

He powered up his rig on battery power and started calling CQ, CQ on 144.200, but at 10am on a Sunday morning, there weren’t all that many folks running SSB on 2 meters. He contacted one ham up in Boerne, TX, but that wasn’t more than 20 miles from his setup location at the park.

Here are some photos….

The much shortened version of my full 3-day Jump Team Boot Camp which was offerred for a July date  has been cancelled due to not enough interested parties signing up.

This was to include such sections as site survey before structures are erected, sheltering and how/where to properly put them up, station operating posts, antenna building and erection, power generation, food support/dining areas, message handling, troubleshooting your station, propagation, water purification, basic survival techniques, creating a complete EmComm cache of gear to have on the ready, etc.

All participants would have been exposed to every phase so they would have been able to “do it all” from scratch in case of an emergency, with session taught by a team of experienced communicators and also survival experts from the military.

Note: My full 3-day boot-camp is still being held in late October. We will go through the same  steps needed to set up and run a complete emergency communications complex at a location where nothing would be standing and included will be a comprehensive book/guide enabling people to start their own emergency communications jump team in their area.

Besides the deer, “Murphy” came out in force when the Bexar Operators Group, W5BOG, assembled for their Field Day 2009 operation at Lost Maples State Park.

Despite “Murphys” best efforts, the Group would not bend whether it be from the 108 degree heat, no wind to drive the wind turbine, lack of park water and sewage due to a clogged septic system, the searing sun which blasted our digital camera after only a few shots nor the nearest ice machine being 5 miles outside the park entrance.

W2IK writes: I have listed a few tips which may make your field day setups more successful and more enjoyable.

1. When setting up antennas within close proximity: If you are using wire antennas such as dipoles, and they run parallel to each other there will be interference on your HF operating bands in the form of hash so arrange them at right angles to each other and at slightly different heights. If you use wire antennas such as dipoles, try to stay away from trap dipoles and use full length antennas instead.  You may also wish to run your dipoles in different configurations such as have one as an “inverted V” and another as a sloper, etc. An antenna cut to the exact band you are using will decrease interference to and from other bands. Do not use compromise or “all band” antennas. On HF, stay away from vertical antennas as they receive too much man-made noise from sources such as generators, etc.

2. When operating within a tight area, as required by FD rules, it also pays to use “band pass filters” such as those manufactured by ICE. I have a full set of these HF filters and they work great. They are only about $ 38 per band and drastically reduce interference from your other operating posts. If your pocketbook can’t afford them, use coax “stub” filters. The lengths of these and how to build them can be found at: http://www.k1ttt.net/technote/k2trstub.html They are simple to make and easy to use. Both systems have been used by the major DXpeditions all over the world with great success. On HF frequencies make sure each operating station is properly grounded. Do NOT use a common ground for all your operating posts.
