Any chance that the component values etc can be posted on here?
EDIT: BTW I've posted the xtal current question on another forum, I'll see what turns up.
Lawrence.
Yes for the first question, he states 'Crystal, select for the desired amateur band', so it seems he is just using the fundamental frequency.
I've attached the whole circuit again, this time with the component values, also attached are coil details for L1, L2 is the same except for a centre tap, but I don't suppose anyone will want to build the second stage.
It will be interesting to see if anyone from another forum can shed some light on this subject.
