      Hi Peter,
      The crystal marked 28.2C69 is actually the 28.224 MHz crystal which will give a 40m center frequency of about 7.055 MHz.  The 40.5 marked crystal is for 30m and will give a 30m center frequency of about 10.124 MHz.

      Hi all,

      I am constructing a Softrock TXRX v6,1 kit.

      The Crystals I have are:-

      28.2069 Mhz


      40.5 Mhz

      The info I have says I should have a 28.224 Mhz for the lower frequency.

      Which is correct please??

      Many Thanks & 73s, de Peter G4WJJ
