Reading up on the Tuna Topper and funding for amateur radio projects

Since we're now blowing FETs on Project TouCans, and KO6BTY and I are giving a presentation about the rig to the San Francisco Amateur Radio Club on Friday, I've been reading up on amplifier theory. I really like this article explaining how the different classes of amplifiers work except for the horribly gendered  first paragraph.

In other reading news, (it's finals week for KO6BTY and I'm getting ready for our camping trip, so mostly all I've had time to do over the last few days is read), Simon Willison pointed out that the Amateur Radio Digital Communications group has grants for advancing the usage and technology of amateur radio. Here are some examples of what's been funded.

And finally, here's a link to the article that taught me how to increase power output on the Tuna Topper by upping the bias voltage. It's an even more cool article now that I know how the calls A Tuna Topper amplifier actually works.

To wrap things up, we're hoping to get TouCans back up and running today. Here's a nighttime look at the rig from the ground. The white object is the 10 meter rig's balun.
