Hello, 1. The comments in Lady Heather are placed there by Mark Sims. There are comments for all kinds of events during the year.
2. Yes, the output of the HP 5065A is 5MHz (and also 1MHz and 100kHz). I have a board from another HP instrument that multiplies 1MHz to 10MHz (there is no identification on the board other than an HP logo, at first I thought it was a 5MHz to 10MHz doubler, but the signal generator and spectrum analyzer set me straight). 3. I actually saw a 5065A recently that had a modification to decrease the C-field sensitivity. It had two 10-turn dial pots, the normal and another that was about 2x10E-14 per division. Unfortunately, I did not take note of the circuit to see how it was implemented.
