Well, my build seems to have passed the smoke test OK. I was able to program it to sweep between 2000 khz and 10000 khz with 500 hz steps and watch the output on my O-scope and frequency counter. The output looks like an OK sine wave. The -10 dBm output is exactly that on my W7ZOI/W7PUA power meter and the output before R19 is 0 dBM. My little homebrew bench frequency counter is a bit "deaf," so I probably will remove this resistor for the counter output (unless there is a compelling reason not to).
I noticed that R7 did get kind of warm, so I may replace the 1/2W one with a 1W version. Seems like a good idea.
Now I have to start thinking about making a case for this FB project.
Thank you, Jim and Jerry! Well done, gentlemen.
