Before I get started, let me explain the reasoning behind this.
I know the FT-817 is not designed to be used as a base station, it's geared more for portable use, and that's primarily why I bought it, for travel purposes, which my job requires now and then. I would like to use it in a base station mode as well, and given its 5 watt output commercial amps are out of the question for the HF bands due to FCC regs. BUT, doesn't mean I can't build one.
So, when time and money (mostly money) will permit, I'd like to construct an amplifier for my rig that will boost it to, say, 50 watts or so. I'm not looking to go big gun, just enough to make ragchewing easier. I've read some material on the theory, but I want to learn more about how you go about designing one of these bad boys. Can anyone recommend some sources? Good books, web sites, etc?
