PY2OHH is a very creative ham with an excellent website full of good circuit ideas. I noticed a neat Colpitts VFO calculator there today. You put in the frequency range needed and the variable capacitor range available and out pop all the capacitor values in the tank circuit.
Since including this link the original site has removed the schematic.
Nice calculator but not much use without a schematic .... can you post one?
ReplyDeleteThe original site Image236.gif is not there.

The schematic does seem to exist on the site, but the link to the picture is wrong.
ReplyDeleteIt seems to be here instead:
