Default Re: HP8640B Signal Generator

The harmonic levels are lower Guy.
I ordered some new diodes from Farnell. It was going to be RS but my main order was double the price of Farnell so I ordered SMS7630-079LF.
I'm thinking I might try two in a doubler cct if one doesn't provide enough voltage. They have a rating of 0.3pF/0.7nH.
A couple of lift repairs tomorrow that have to take precedence.
Sporadic E or tropo. I remember the days of black & white Band I watching bullfights from Spain and even a signal from South Africa up in Liverpool.
