Ham Shack Cam
Welcome to Matt's (N6EAJ) web page.
Over to the right side is the Ham shack cam. It is updated every ten
I had a DIY (do-it-yourself) audio web page on the SDSU (San Diego
State University) server for many years.
It was a collection of some of my audio related projects ranging from a
class A 20W/channel audio amplifier to a 15" cylindrical sub woofer.
It was interesting to hear from people from all over the world that were
working on audio projects (the same fun I have with Ham radio).
I haven't done any audio projects for awhile, but you can still check
DIY audio archived site.
Solid State 600W HF amplifier project:
I started this project about 10 years ago and got through a lot of it (put together the main board, made and tested the output filter), but eventually burnt out on it. Someday I will return to it. It is based on an application note from Motorola. The main
"RF deck" is part of a kit, but it is up to the builder to provide the power
supply, output filtering (to keep the harmonics low and the
amplifier legal), protection, and everything else. It sounded like a
good way to learn RF (the best learning is hands on).
You can see details on the amplifier
