Is there a typo in the specs of their 435 and 145 MHz converters? The frequency stabilities are specified at a whopping 25 ppm.

Joe,
The spec reads "+/- 25 PPM versus operating temperature" which is typical for a crystal oscillator in that frequency range.

Looking around at other, similar devices they carry, they show 2.5 PPM. Probably just a missing decimal point.
