what JFETs did you use on the VXO?
ReplyDeleteThe VXO oscillator has 1 mH RFC which I recall, DemAw use a lot.
ReplyDeleteSRF is < 1 MHz and not so good for 23 mhZ oscillator. Just 5-10 mickrohenry all is what needed.

Alan: I used MPF102s. 73 Bill
ReplyDeleteVerdeep: Thanks. That may help explain the low freq oscillation problem I had. For now, the 1mH choke is working OK, so I'll leave it in mine, but I'll update the drawing. 73 Bill
ReplyDeleteBill,
ReplyDeleteWhich CAD package did you use to get that hand-drawn look.
I like it!
I use PencilPAD (tm). It is not really "cutting edge." It is more "sharpened edge." Perfect for discrete, analog, HDR projects.
