LOL good video Joe.

Found another example of superior quality control. One of the top covers they missed countersinking three screw holes (1st pic).

I'm going to use the boards that came with the metal cases now for this project. I changed the input components as has previously been explained in this thread.
Each AD8307 chip can have a slightly different response, the most important is as follows:
log slope 25 (+/- 2) mV / dB
log intercept is -84 (+7 / -3) dBm
So at a minimum I'll have to re-cal but I think I'll more accurately determine these values for each board. I was using the "typical" values from the datasheet in the software: 25 mV / dB and log intercept of -84 dBm.
I labeled the boards "A" and "B" (I know pure genius). Using my Agilent 8648A I made a series of measurements and found the responses of the boards as follows:
Board "A" has a response of 24 mV / dB and a log intercept of -84 dBm
Board "B" has a response of 25 mV / dB and a log intercept of -82.4 dBm
That's all in-spec, but now I know the actual measured values, to be used in the power calculations.
My collection of parts at the moment shown, except the case. I called Amazon today and he said they put my order in the wrong bin and it returned to some Amazon warehouse. Supposed to be sent out again -
"don't worry".
