What a great writeup, Roger.  Thanks!

73,

Hal W1NN

PS:  Hope I can make it next year.

> lunch.  At that time, we start to load 
> all the equipment to transform the family van into a
> contest station for the weekend.  
> Here comes the understatement of the year; it is so
> much easier to find and fix the 
> problems while sitting in your driveway ahead of time
> than to fix them on the side of the 
> road in a panicked-state during the middle of the
> contest.  So, Saturday afternoon after 
> loading all the equipment, we are busy testing -
> looking for anything we can possibly find 
> before the contest starts.  Using the final
> configuration, we go through all the bands 
> checking for any interference, rfi, hash, or whatever
> else that may slow progress during 
> the contest.

> So what does the equipment list look like for KF9D/M? 
> Here is the rundown, with a lot 
> of redundancy in case of equipment failure.  
> HF Transmitting rig: TS450S with autotuner.
> Back-up HF rig/spotting receiver: TS430S.  If you
> think it is fun trying to get the 
> interference down at field day because of too many
> close transmitters, try doing it in one 
> vehicle with antennas and rigs 3 feet apart all
> operating from the same power source.  
> That is what it takes to get a spotting receiver to
> work next to the transmitter.
> Computers: two identical IBM Thinkpads configured
> identically with 12 to 16 volt 
> inverter supplies, one for logging and one for
> APRS/navigation with GPS receiver.  They 
> can be quickly interchanged in case of failure.
> Antennas: Homebrew antenna number 1 allows
> simultaneous operation on 3 bands, either 
> 40/20/15/10 meters.  Subscribing to the theory that
> size does matter, homebrew antenna 
> number 2 is a trailer hitch mounted monster for 40 or
> 80 meters.  This antenna gets really 
> strange looks while on the highway, all part of the
> fun, right?  I noted one passing car 
> taking our picture as we motored down the interstate! 
> A coax switch arrangement 
> connects the proper antenna to the proper rig.  Band
> changes are instantaneous with the 
> flip of a switch.  Backup antenna: multiband Outbacker
> with roof magmount.
> 2 Meters: Dual-band HT with 60 watt amp to 5/8 wave
> roof mounted antenna.

> Sunday morning arrives.  The van engine starts at 6:50
> am, and is never turned off until 
> safely back in the driveway at 9:30 pm.  With the high
> gas prices we decide to forgo the 
> extra expense of an overnight stay, instead opting for
> a marathon day on the road. With 
> 275 miles to the start, we turn on the 2-meter APRS
> station.  The pre-contest trip 
> progresses, and turning down the final one-lane gravel
> road while carefully watching the 
> low-hanging branches, the GPS navigation and computer
> mapping come in handy to 
> confirm the starting 3-county corner.  About a mile
> from the start, we come to a sign that 
> reads At Grade Crossing.  What does that mean? Well,
> it means that we are about to cross 
> a creek without a bridge!  Luckily in October, the
> creek is dry.  As we approach the start 
> point, there are no signs at all indicating a county
> change.  This is rural!  (See the IQP 
> photo area for this location)  After we transmit a
> couple of spots on our starting point, we

> on the band than desired due to the 
> severe RTTY congestion.  The one hour earlier contest
> finish this year meant an extra 
> hour of overlap with the RTTY guys.  Also, the earlier
> finish meant less time on 80 
> meters, which, even from the mobile, was producing
> good rates during the low sun spots.
