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.
