Did you get a chance to look at the spectrum?
That seems like a lot of power for BS170s!

*** It's a digital PA. In the schematic, the BS170's are fed
RF by LOGIC gates. I think it's what's called a "class E".

They don't even have heat sinks. They output 5W without
breaking a sweat.

The spectrum looks good on my FTDX10. I haven't hooked it up to
a spectrum analyzer yet.
