Hi,
I need a good second LO at 44.545MHz.
I have a few crystals that I bought, that are say they are 44.545MHz, but
are really 44.548MHz. I tried pulling the frquency somewhat, but to no
great avail.
I have read that overtone crystals are hard to pull.

Does anyone know where I can get good quality crystals at this frequency?

Or how I may combine some easily available crystal frequencies to get
either 44.545MHz or 45.455MHz?

Best regards,
John.

Hi,
I would like to thank Joe, W3JDR and Tim Wescott for thier help. I made a
common base colpits oscillator, as per the ARRL handbook, with a 2N3904,
and got it working at 45.455MHz...Great.

That's a lesson learnt.

Best regards,
John
