ARRL SEPT VHF QSO CONTEST

                                        ARRL SEPTEMBER VHF QSO CONTEST 

 

                                        Rear mounted yagis for 23 cm, 70 cm, 1.25 m and 2 m.
 

Finally, I decided to stop procrastinating and I took some steps to turn my Silverado into a more serious rover.  I've roved before with Herbert AF4JF and Harry WA0CNS to grid squares EM48 and EM49, but those outings were more portable set-ups.  They involved going to location and setting up, tear down and resetting up at another location. I wanted to get more serious about roving.

  I wanted to minimize set-up time.   I have end mounted yagi antennas which require a mast with a good base.  My past, portable set-ups varied in quality and overall were not that good.  This time I purchased a tripod with a steel mast and bolted it down to a plywood sheet.  I then put a heavy weight on the plywood and the antenna system stood up to highway speeds.

On the other hand, I found out the hard way, my folding bed cover needs to be strapped down.  On Sunday, while traveling up Interstate 55,  heard a "boom" as the wind blew my cover backwards against the antenna mast.  The cover blocked my rear window vision. I've done this before and never had a problem.  Then again, I wasn't traveling over 60 mph.  One lesson learned.

I also need to get an antenna switch and longer coax runs.  I fed my coax through the passenger side of the truck.  For the January contest, I plan to use foam rubber to fill in the air gap between the window and the coax.

This turned out to be a good trial run.  Debbie KC9ULA and I decided to not make this contest a "full-press effort."  On Sunday, we wanted to be back in time to view the KC Chief's vs. Eagles football game.  KC lost BTW...drats....  This decision limited our contest time, but this was a trial run.

The weekend of September 13-14 was hot (at times 100 F on my truck's thermometer).  We were under the influence of an weaker, omega, high pressure system.  Humidity levels were way down and so was propagation.  Many of the ops we worked noticed poor, propagation on 6 and 2 meters.  70 cm had better  conditions it seemed.  

On Saturday, Debbie and I started off at the park near St. Charles Community College, near Cottleville, MO EM48.  We made contacts with Herbert AF4JF, Mel K0PFX and Jeff K9KLD in Maryville, IL EM58.  From there we went to Foley, MO EM49 and worked Herbert, Jeff.  Not a bad start for our first day. Herbert convinced us to try again on Sunday.

 Sunday, September 14

 I'm glad we decided to go.  This was going to be a busy, full day in that we wanted to be back in time for the Chief's.  We were on the road by 9:30 am and we worked Mel, K0PFX, en route to EM 58 from EM 48 (I-270).  Our first stop was at a park in Troy, MO, EM58.  I couldn't hear Herbert AF4JF in EM48 or Warren WD9EXD in EM57, but we did work Jeff K9KLD from the park.  Jeff is only a few miles away.  I don't think we'll use that park again, too many trees and houses nearby.

From there we went to Staunton, Il in EM59.  We parked at a dental office located on a hill.  This turned out to be a very good spot.  I worked Warren WD9EXD, Jeff K9KLD, Tony KG9AP, and Gordan N9HYC. We did some band running.

On our way back home, we stopped again in EM58 at a higher location near SIUE.  I was able to work Herbert, Tony, John KE9CIP and Jeff from that location.

STATS 

Debbie and I activated 4 grids, EM48, EM49, EM58 and EM59.  We drove 300 miles on this weekend triip.  We worked 3 grids EM48, EM58 and EM59.  We made 37 Qs, 55 QSO points, 19 mults for a claimed score of 1,045 points.

FYB0 (Freeze Your Buns Off) Microwave Attempt

The weather forecast wasn't especially encouraging.  Debbie and I were up before dawn and we were almost ready to go by our planned time of 7:00 am and we were only 15 minutes late.  That's good for me, since I am on "Ochu time" which translates into at least being 30 - 45 minutes later.  Our eleven old son, Roman didn't complain and he, too, was ready for the trip.  My idea of putting some Anderson power poles on one end of a pair of wires and a cigarette lighter plug on the other as a means of hooking up my 10 GHz rig in the car to warm up the 10 MHz oscillator worked well.  I did not have my usual 20 - 45 minute waiting period.

By 9:00 am, I am up and running at the grid corner of EN50aa and EM59ax and not far at all from the corner of EN40xa and EM49xx (about 200 yards).  I first try  to work Zack, W9SZ on the hill in EN50rl about 81 miles away.  I can copy his signal just out of the noise and there is severe QSB.  Likewise with Zack.  We both are experiencing 30-35 mile/hour winds and the temperature is about 42 degrees.  It is cold outside. The 1.2 GHz antennas behave more like wind vanes so we didn't even attempt that band.  So, Zack and I almost made a two-way, but not quite.  Oh well.

I next called Jim, N5MU at the Y in EM48sq about 96 miles away and we tried, but neither one of us heard even a peep.  The same story with Jim and Zack.  At this point we are struggling to keep our dishes from toppling over in the wind.  The wind broke up any ducts that may have formed so we called it a day.

I gave Ron, W9ZIH a call, but he was in the middle of a 2 meter QSO and he'd be happy to work me later and that was very nice of Ron, but I decided not to struggle with the winds and raw temps so we agreed to make it another day.

The grid corner of EN40, EN50, EM49 and EM59 looks like it will work.  I met the manager  of the property and he'd check with his boss to see if I could set up in the actual corner.  Otherwise, he was fine with me staying of the field edges. 

So what did I learn on this excursion?
*  Zack, Jim, Debbie, Roman and myself are microwave troopers.
* It was COLD outside!
* Strong winds are not conducive to good microwaving
* My DC power cord from the van's cigarette lighter to my rig is a great idea!
* Quicker set-up time to get on the air.
* The new grid site looks promising.
* Starbucks coffee tastes even better in 42 F temperatures and strong, gusty winds!
* A big THANK YOU to Zack and Jim for braving the elements!

       Debbie, Roman and I stopped for lunch at the Golden Corral in Springfield, IL.  Notice the landmark smoke stacks from the electrical plant along I-55 about 2 miles away from us.
