Sourcing crystals for a G2DAF receiver

May 26, 2010 0 Replies

Dear All, I have a colleague who wants to build a version of the G2DAF receiver which needs a set of crystals with unusual frequencies. The ones on his list are;



Freq/MHz Category ======== ========



7.0 Fundamental
9.0 Fundamental
12.5 Fundamental
19.5 Fundamental
26.5 3rd Overtone
33.5 3rd Overtone
34.0 3rd Overtone

The only one I have managed to source so far is (a very close match for) the 9.0MHz. Short of having bespoke ones made up, which is going to be relatively expensive, I wonder if anyone knows where he might get these items?



Many thanks Tom Crane
