John, Io have purchased some 100 MHz xtals through ebay. Plese give me Your adress then I will send You two of the xtals.

Henning I hadn't thought of eBay. Thanks for the offer. Before I put you to that trouble I have a couple of leads on local sources. I'll let you know if they don't pan out. And thanks again for the kind offer. John Shepherd

Betreff: [emrfd] 100 MHz Crystal Source

I'm half-way through building the W7ZOI Spectrum Analyzer, as described in
Section 7.8 of EMFRD. But I'm stuck on the 100 MHz second oscillator-mixer
module. The 100 MHz. crystal, that came with the kit, seems to be
inoperative. If I replace the crystal with a 51 ohm resistor, I do get an
unsteady 100 MHz. signal out of the mixer. But when I re-insert the
crystal, there is no oscillation.

It's difficult to buy this "Thru-Hole" crystal. Digi-Key and Mouser don't
stock it. Manufacturers like Vectron and ECS sell through distributors that
aren't interested in small orders.

Can anyone suggest a source? Or does anyone have a spare in their junk box
that I could buy? I'd like to get two, and have one as a spare. I don't
think that the specifications are critical.
