to the performance level of either one. The 10811 is probably the easiest thing to both identify and find. You see them selling anywhere from $100 to $200 depending on just how patient you are.

just for show-and-tell: I've been disassembling the Schmomandl ND100M oscillator block to see if I could use it. I figured, it's the bird in hand, and once was a high quality piece of equipment so maybe... The physical construction is great. Lots of fine pitch slot head machine screws. Lots

That is a really cool picture. Can I be like you when I grow up? I've figured out which of these silvered modules in this Schomandl sig gen is the oscillator (the one that got warm). I have to figure out if it is voltage adjustable in some way. Does anyone use mechanical adjustment with a

Bob asks a reasonable question: What kind of accuracy are you trying to obtain? Bob I would like to end up with something that is usable on a home electronics workbench. Something like a Z3801. Something I can use if I ever try to do some goofing around with microwave radio operation.

I'd like to build a GPS disciplined frequency standard. I am slowly gathering up pieces. I have a Trimble Resolution T GPS card that appears to work, and an antenna for it. I'm thinking now of the oscillator part. I have two Racal 1992 counters with the stable oscillator option (probably
