A kit I'd like to see.

[Conrad Hoffman]

An Opinion,

Building a really good VFO is not all that easy.  I have done them from
scratch and have assembled a couple while doing a Heath Marauder and Apache.
The best of the bunch is one I made using a capacitor from one of the ARC
units, which is really a beautiful variable.  Hate to have to buy one new.
It was also built like a tank.  All of these were tube circuits, but some of
the same mechanical and thermal problems still exit when you go solid state.
I have seen some designs that will do the job, but they all tend to get sort
of exotic in order to achieve real mechanical, electrical and thermal
stability.  Would sure be interested in trying another VFO if someone has a
new up to date circuit that doesn't require parts that are overly hard to
obtain.
