ARRL VHF Contest January 2005

 

The antenna setup just before departure:

Top to bottom: 6M loop,  2M at the top, 222, and 432 and 903 on the bottom level, 1296 in the middle center.  The front support masts are solid 1.25" fiberglass rod.   The rear is a hitch mounted 6061 thick wall pipe.  I have a heavy duty roof rack mounted support channel running the length of the roof that I can put brackets onto without damaging the roof.  

 
January 2005 VHF Contest pictures from CN98 on Green Mountain @ 2950ft.

K7MDL/R 10GHz setup with towel to keep the light rain and cold wind off.  Pointed south at N7EPD and KB7DQH/R on Poch's Peak in CN96 84 miles away on USB no problem.   This is Sunday afternoon on Green Mountain in CN98 at 2950ft.  The snow topped mountain to the left is Mt. Pilchuck with the often visited "bench" area visible just to the immediate left of the dish.   Everett is about 90deg to the right from this angle.   The black box on the back is velcro'd in place and is a 15.36MHz TCXO connected into the directional coupler to act as a reasonably accurate marker generator at 10368.088MHz.  I added a crystal oven to the brick PLO last week, and after a short warm up I found Eric*2 within 3 KHz of where I expected.  145.092 should be 10368.100 after full warm-up.   W7NBH in eastern Washington CN96 came in strong on this angle on 6M through 1296, presumably working the bounce off Mt. Rainer.  It was mostly dry except when we wanted to work 10GHz!

The FT-817 IF rig display shown in the picture above is the S7/S8  from N7EPD & KB7DQH/R stations.  They were about equal in strength with roughly equivalent stations at 15mW.  My setup is about 90mW at the dish feed which is a reverse splash. which from what I can tell might be only 20-30% efficient.  Most of the dish is used to support the front cover, not reflect signals.  The noise floor sits about S3/S4 so they put out a strong signal, intercom quality.

The above pictures are the rover truck interior setup with and without flash a little later in the evening at CN98.   The antenna setup (8ft yagis on 144, 222, 432, 903, 1296, and a 6M loop) is about the same as in the other pictures on this site, except I replaced the 1296 antenna since the old one was fragile and self destructed over several trips and was non functional last September at CN78.

Traveled 4 grids, CN87, CN97, CN88, and CN98.  The plan was to limit the road miles, stay closer to home, but extract every last QSO from each of the 4 grids.

Started off at high rock road in CN97 at 900ft, then moved to Mt. Anderson at 3000ft. south of Bellingham to be able to work VE7DXG/R and VE7DAY/R roving down east Vancouver Island.  I worked a surprising amount of VE7 stations especially from CN79 that I have never heard on before on all bands to 1296.

I returned home Sunday at 2am and then resumed at 10:30am Sunday to stop at Monroe High School parking lot, which was not a bad spot at all for a easy quick CN97 stop, and then stopped at Lord's Hill Regional Park at 600ft in CN87 south of Snohomish, WA.  Finished the contest in CN98 on Green Mountain.
