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?

I use Quartslab. They are good and like to work with experimenters. Their prices include shipping to the US.

Hi Pat,

Does Quartslab have a website? How do you order from them?

I believe you can do that without a custom crystal by tuning the 110Mhz IF up to 110.7Mhz .... 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 resoluti

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.
