For you more experienced homebrewers - can anyone tell me why varactor
diodes are not more widely used in QRP VFOs? It seems to me that their
much smaller size and mechanical stability, compared to air variable
caps, would make then ideal for QRP gear, especially backpackable gear.
There must be some deep dark secret about these that I don't know.
Or is it just a small capacitance range?
