Message Date From Subject 2887 2009-04-08 16:54:23 Phil Sittner Crystal Sourcing I'm looking for a good source of custom quartz crystals. I need to modify my w7zoi/k7tau SA tracking generator to support a 10.7 mhz IF. Does anyone have a recommondation for purchasing in single quantities?

Since the 1st LO is uncalibrated it doesn't really affect the performance ... At least that's how I did mine and it seems to work great

I need the crystal for my tracking generator. The need is to maintain the IF offset between the second local oscillator and the tracking generator. Last night I did some searching and found some crystals at Surplus Sales of Nebraska--I'll be using a 98.9mhz in the second LO and a 109.6 in the tracking generator. I think this will work out just fine. Thank you for the recommendation and I'm looking forward to adding the narrower resoluti2902 2009-04-09 19:07:42 Wes Hayward Re: Crystal Sourcing Hi Phil,
Yours is the best possible solution. Cheap, but to the point. Way to go.

Thanks for your words of encouragement. These days it's important to incorporate the best of both worlds-use the new SMD and digital products and take advantage of what's lying around. Have a great evening.
