10.7 MHz BPF for v6.0 IF use
SoftRock operated in 1/3 sub-harmonic sampling mode. Reverse audio cable connection to board with tip going to R on board and ring going to T on board.
L1 9T of #30 on a T25-6 core (0.22 uH)
L2 28T of #30 on a T25-6 core (2.0 uH)
T1 8T of #30 on primary and 4T of #30 in each of the two secondary
"bifilar" over the top of the primary on a T30-6 core (0.24 uH on primary)
C21 = C23 = 1000 pF
C22 = 100 pF
Crystal X1 is 14.318 MHz

I am trying to make my V6.1 board work as a 10.736Mhz IF.
I remember seeing a message from tony that some parts would have to be
changed in order to use a common 14.318Mhz clock xtal, but can't seem
to find which parts need changing.
If anybody can please forward me the changes.
