Hi all
Has anyone made the fsk modem by Rildo Pragana?
Im thinking of constructing it but am unclear on a few points.
1.
C9, C11, C13, C14, C15 and R8's values are unclear. Does
anyone know what they should be?
2.
Transformer T1's size or value is unclear.
3.
Will the modem work on Australian phone network?

Can anyone fill in the blanks?
Thanks
Justin
