Hi:
That circuit should work. The exact value of the filter capacitor is not
critical. Lead length is important. If your copy look EXACTLY like the
pictures then it could work. The diode pictured is important. A common
glass type diode will not work well. Also the pictured diode type is very
static sensitive and should come to you wrapped in metal foil. If it wasn't
likely the problem is a bad diode. Building things for this high of
frequency is tricky and if any short cuts are taken it will probably stop
the device from working well.
