The original BITX20 is getting rather old.? After several thousand posts
there may not be much more to be said about that design.? There are
still kits available for BITX-xx transceivers, but many who built it did so
from junk-box parts which allowed a great many modifications, some of
which have been included in present day BITX-xx builds and products.
If you scroll back into the older posts on the discussion group you will
find those older BITX-xx related posts.?
Single-band BITX transceivers have been built for almost all the HF and
LF bands.? If you are interested in building your own BITX from scratch,
you can benefit from learning to use a Spice Circuit Simulator ( many use
LTSpice, free from Linear Technology Systems) as a way to visualize how
each individual stage of the BITX actually works, and to play what-if
games with the design.?
