2021 CERA Enduro pictures - Net Control

Hi folks,

Fun event, for sure! A lot of noise when the bikes were around (and
these were supposedly the quiet ones), but very peaceful when they
weren't there. Light breeze, periods of direct sun but mostly light
shade through the pines. Lots of dust.

Radio operations were fairly normal, trying to keep track of the riders
when the sweeps failed to show. The event course wasn't published for
security reasons, and the very few who did have access to it only had a
piece of the picture. One broken bike, and two that ran out of gas,
giving locations that had no correlation to points on the Forrest
Service map. I'm really curious about the back-story of the place
called "Rock Lobster". A few random non-participants on the trail
causing confusion. Fortunately, no injuries, and I don't think they
lost anybody (though a few apparently discovered some "alternate paths"
between a couple of the checkpoints).

I remembered to take some pictures this time. See views of
the Net Control station that I operated with Aaron, K6ABJ on our Dropbox site.

Greetings,

Please enjoy the photographs in Club Dropbox from Endura Race 2021, Darling Ridge post. AI6US and AI6JB ran HF during the weekend with a homebrewed 80m antenna at 100', launched into treetops by home made antenna-canon. Meanwhile, there was a GP-95 mounted at the top of another nearby tree for maintaining Darling Ridge's crossband comms. This is everything ham radio is about!

Please add your 2021 Enduro photos and experiences

Re: AM radio propagation #antennas

Possible, but kind of unlikely that it's related to that station.  I suspect all AM stations come in a bit louder over the bridge, and that might make for an interesting test.  Could just be a difference in what appears to be ground to the car's electrically very short antenna.

I have a vague recollection of a similar effect from the deep past, but can't quite place it.  Now it will keep my up all night trying to figure it out.

Just a thought.  Could the bridge be acting as a kind of travelling wave antenna, like a Beverage, and re-radiating to the vehicle driving across...?

Foresthill Fire District has an emergency radio operating on 1020 AM under TIS
rules.  The usual distance/signal falloff has been noted in contour mapping.
Note, no spectrum analyzer on hand, just receivers with relative
dBu/v readings.  Power is 4 Watts CW, but with 90% mod when messages are played;
PEP 7-8 watts estimated (simple power meter) Inital setup of the transmitter field density
is 2mv/.93 miles. Antenna is at 3200 MSL, in downtown Foresthill.

However, it was noted that the signal was higher, and obtained receiver quieting
while crossing the Foresthill Bridge at about 15 miles distance.  From that point towards
Foresthill, the usual PGE, growlights and cable system noises interfere as expected while running at
this low power level.  Why does it sound so good there?   Is it the bridge structure and groundwave?

Take a crack at this one Extra Class!

Two of My Favorite Childhood Memories...

Alan - W6WN
 

Cruising around on the World Wide Web today, I found this image of Mickey Mouse and radio, two of my favorite childhood memories:
And the image reminded me that, when I was a kid and misbehaved, my parents would send me to my room. But they soon realized that was no punishment. I loved my room because that's where my radio lived. And my radio put me in touch with the Whole Wide World.

And that was the original, and best, "www" of all. 🙂

I have mudcovers on the tires...prevents splash. Though I suppose with rain, I should put a gallon ziplock bag in the bag to put everything in just in case.

Hi Carl and group. I asked him via marketplace to see if he has any more 12V panels.  Waiting reply

[HamSCI] HamSCI Telecon Today: Informal Radiosport Discussion

Jef - N5JEF
 

Forwarding this about an open web discussion today at 6PM Pacific time about plans for the HamSCI Radiosport league.

HamSCI is group that's a little more science-oriented than most.  That, combined with the sport of radio direction finding (RDF) might be of interest to some on this list.

Hi all,

Today's 3pm ET telecon will have an open discussion of plans for the HamSCI Radiosport League. Please bring your thoughts on contesting for science: datasets that would lend themselves to radio contests and contests that would lend themselves to data collection. See you there!

73,
