San Antonio Hams

Members of the Chaparral Amateur Radio Club (which happens to also be the Guadalupe County ARES group) set up and tested NVIS antennas at the county EOC in Seguin on Sunday, September 13th.   Their goal was to design an antenn that could be raised or lowered from the ground, in order to find that sweet spot where the noise floor was the lowest.  

We’re hoping to get an after action report to be added here in a few days, so please check back for more details about the results of this test.

The following photos were taken during the event by the well known local NVIS antenna consultant and guru, Bob W2IK, who was obviously present but not shown in the photos since he was on the other side of the camera.

I watched this video and thought “Wow, KC3VO is like W2IK on steroids”, but after second thought, decided that even though W2IK likes to invent stuff like this that works better than the ordinary store bought stufff, but he wouldn’t be dumb enough run something like this so close to his own body.

At 1kW power, Bob Curry KC3VO (the inventor) says he gets 1 hour of transmit time, and about 15 minutes at the full 2kW power level. The antenna used for the demo was restricted to 500watts.  I checked out KC3VO on www.qrz.com and found that he lives only about 3 miles north of Washington, DC, in Adelphi, Maryland, and has a Honda Goldwing motorcycle set up for HF operations also.  He works as the full time commercial transmitter engineer for a high power UHF TV station, which might explain some of his need doses of high power RF signals in his body. 🙂

Information about the Bexar Operators Group, including what they have done and their planned events, can now be found at their new site: Bexar Operators Group – Home  

This club is an active amateur radio group and not a social club. Up coming events include participation in this year’s JOTA event which will focus on operating “green” with solar panels and wind turbines.

We also sponsor the annual “Jump Team Boot Camp”. All types of antenna testing and field operations are done in order to make members better operators in both contests and during emergency conditions.

This webpage also includes two links which will get you to W2IK’s old AOL webpages (45 of them) that were thought lost. Between the two you should find them all!

For further info, contact us through our new web page or at: W2IK@arrl.net

Planning is good, but sometimes even the best planning needs some “tweaking” in the real world.

Being flexible in field contesting, just as in emergency communications deployment, is the best way to get things done.  All ham radio operators need the experience of going out in to the field to do this sort of thing. It makes them better operators.

I tend to over pack my truck when it comes to doing ham radio events, and for good reason: You never know what obstacles you might encounter and how to overcome them. However, this time I had a minimal amount of gear and supplies. This was the height of my “daring”. Never again!

Lesson number one learned: Pack for the worst, pray for the best and be happy with the in between. New hams need to remember this

I wish to thank all of those readers who have expressed their concerns over the loss of my van last Sunday to the engine fire. 

The old van now has a new home in a junkyard somewhere in Texas, and I now have a new(er) van sitting in my driveway with seriously less mileage and years than the old van had on it.  

The new van is a late model Chrysler Town & Country mini-van with a factory installed alarm, dark limo tinted windows, sliding doors on both sides, and more option packages than I’m normally used to having.  At first, I was concerned about the black exterior causing the van to be too hot, but actually, it hasn’t been any hotter than my old van got on a summer day. Guess that’s why I always put that window shade in the front  windshield when not driving.  Those shades really work!

I sent out tweets and emails to various groups and individuals asking for input / suggestions on the best way to install the antenna in this type of vehicle.

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 Bexar Operators Group will be operating W5BOG during the “North American QSO Party” on January 17-18th 2009. This is a SSB only contest. We have tagged this as “Operation Deep-Freeze” as we will be operating from a field location, CHOKE CANYON STATE PARK (Three Rivers) – CALLIHAM UNIT (Screen Shelter Area) – NOTE LOCATION CHANGE!   This is a 12 hour event and, as in the past, we will continue to do field testing/experiments of different antenna systems to further our knowledge of short-term, deployable antennas and to enhance our camping abilities. 

If anyone is interested in joining, please email alonestaryank@aol.com with your interest. 

ARRL WEST COAST CONVENTION – “With A Little Texas Touch”

In mid July, Bob Hejl, W2IK, was approached via email by Per Brashers, KI6JJS, requesting permission to reprint several of his Emcomm and antenna building web sites to assist in presenting a RACES forum at “PACIFICON 2008”, which is also known as the “Dayton Of The West”. It is the major ARRL West Coast convention held in mid October and offers dozens of lectures, a swap meet, exhibits, demonstrations and even an operational JOTA station. To learn more, see:

http://www.pacificon.org/index.html

Emails were exchanged and the request soon escalated into more than simple reprint permission. KI6JJS also requested assistance with creating his actual presentation script.

BEXAR OPERATORS GROUP
TESTS NVIS ANTENNA THEORIES
DURING THE TEXAS QSO PARTY

A group of hams representing the Bexar Operators Group, and using the W5BOG callsign, drove over 100 miles to Garner State Park to operate during the 2008 Texas QSO Party (September 27-28) handing out contacts from Ulavde County.

While we were there, we also tested our camping/deployment abilities and did some tests of NVIS antennas at different heights.

Not wishing to get “soft”, we reserved a tent site to operate from rather than a cabin. Krissy, KD5YTN, set up the eight man tent while Bob, W2IK, began the station set-up using a 10×10 screened “EZ Up” as the main operating area.
