      Can you let me know what xtals come with the V7, and also if you have an xtal for my V6 for 30m (must be around 40.5 megs).

      Cheers

It should also cover 1741-1837. I have a number of these xtals available if anyone in Australia is interested in changing the frequency range of their softrock.

      > The v7.0 is intended as a 10m IF for converters and with the 28.06 MHz crystal supplied with the kit the coverage is +/- 48 kHz each side of 28.06 MHz when used with a soundcard that can sample at 96 kHz. The quadrature clocks result from using a phase shift network prior to a voltage comparator to get the clock that is shifted by 90 degrees.
