[aprssig] Operation Uinta Report

Operation Uinta turned out differently than planned, but I suppose all such 
operations have their unexpected twists and turns.  I planned a multi-day 
backpack trip.  It turned out to be a car-camping experience.  My initial 
acclimatization time at 10,560-foot elevation was the only period when the 
weather was completely free of the threat of thunderstorms.  I experienced 
one such storm directly.  One lightning strike was extremely close, as I 
sheltered in the car, grateful for its insulating rubber tires.

I received no APRS Operation Uinta messages at all.  I was, however, able to 
send two e-mail messages via the APRS system.  Here’s how I did that:  using 
the APRS message system in the Kenwood TH-D7A(G), I went to Input, then 
under TO: I wrote EMAIL and then I began the text with the e-mail address 
following by a space and the rest of the message.  The e-mail message had to 
be extremely brief, but it worked.  See 
http://www.findu.com/cgi-bin/msg.cgi?call=N7RR for examples of APRS 
messages.

I want to thank C.H. Stewart, Seabury Lyon, Don Wilhelm, Howard Kraus, Jack 
Bennett and Erik Weaver for their advice about dealing with static discharge 
from a kite-lofted antenna.  Since I never reached a summit, I didn’t ever 
use a kite to carry an antenna. I was equipped with a 1.2 megohm shunt 
resistor, however.

W7GHT, W5UYH and W7GB provided excellent service by relaying formal traffic 
through the Idaho Montana Net (IMN: 0300Z daily on 3647 kHz) to my wife, 
K7MWP.

The announced exchange for Operation Uinta was the 6-character Maidenhead 
grid and name.  Only three operators furnished their 6-character grids.

All contacts used CW.  Here is the log:

Thanks to all of you who participated.

I found that the end-fed wire & counterpoise antenna system did not load 
very well using the internal tuners in the KX1 and K1.  (Bill, W7GHT, a 
renowned CW traffic handler, and recent inductee into the Idaho Amateur 
Radio Hall of Fame and recipient of the Presidential Volunteer Service 
Award, managed to copy my traffic one night while my SWR was 7.6:1, 
according to the readout on my K1.  Margaret and I stopped to see Bill in 
his Boise home on our way back.  We were intrigued to hear about his service 
as a high-speed CW operator and as an OSS officer during World War II.)  
Although I’ve written a favorable review of the Elecraft T1 for a future 
issue of QST, I didn’t bring the T1 along on this trip, relying instead on 
the optional tuners which are built into my KX1 and K1 rigs.  Testing the 
KX1 and K1 tuners in my backyard in Western Washington, with moist, 
clay-rich soil, worked fine, but in the arid Uinta Mountains of Utah, I 
assume that the ground conductivity was too poor to provide an effective 
capacitive ground coupling with my two counterpoise wires.  So, I retreated 
to the town of Roosevelt, Utah and bought some 18-gauge zip-cord.  I 
fashioned that into a zip-cord dipole, 65 feet on each leg, tied at the 
feedpoint of the legs with a figure-8 knot.  The zip-cord dipole loaded fine 
on 80, 40, 30 and 20 m bands.  The 18-gauge zip-cord is too heavy for 
backpacking, however, so I’ll duplicate the antenna using lighter-weight 
22-gauge speaker cord for future backpacking.  I just bought a 100-foot roll 
today at RadioShack.  We’ll give it a go.
