[time-nuts] 10 MHz Band-Pass Filter Needed

[Brian Kirby]

A quick filter would be a series resonance circuit.  My notes show that 
on a circuit that was 10 Mhz and terminated into 50 ohms load, I used a 
10uH choke and a 22 pF cap.  Both of these items were off the shelf , 
the cap was a silver mica 5%.
