RIP – John Butler KF6GNI (sk)

My good friend, and Radio Sausalito consulting engineer John Butler passed away recently. I’ll try to get some more photos of his amazing radio “shack” which, it turns out, had over 100 radios in it. All in perfect working order. I look forward to displaying the “cream of the crop” (as he called it) recievers [...]

KCSM 91.1 antenna

Here’s a shot I took recently of the KCSM FM antenna tower on the campus of the College of San Mateo. You can see the primary antennas on top (4 bays) and their backup is underneath (5 bays). I think the little guys on the back are just antenna mounts, not actual antennas. It’s a [...]

A brief snow shower coated the pavement, but since the air was so dry, any snow in the sun almost instantly evaporated. The result makes it look like it only snowed in the shadow of the car:

Thinnest runway in america?

This is me lying across the runway at Ft. Bragg, California airport (82CL). Thankfully there’s plenty of grass on either side of this runway for the planes to land on, but the total width of the asphalt must be only about 12 feet wide! That would make it the thinnest runway in the US that [...]

Minds Over Matter (KALW Show)

Propagation study for Police Volunteer Group: VHF vs. UHF

I designed and carried out a propagation test in 2006 for different radios that the Police Department was purchasing for its volunteers. We tested the ability to communicate between eight locations in town using three different radio technologies. The results were that UHF (Business Band) was by far the superior technology for Sausalito’s undulating terrain. [...]
