how about you guys fitting in _our_ group ??? :-)

Many of us (I being one of them) consider that LF may be one of the last frontiers
of _experimental_ ham radio . Lots of (if not most) things have been done in HF and
VHF. In Microwave, most experiments may have to do with using either old Navy or
Air Force equipment, and very expensive test equipment.LF, on the other hand, has
the advantage of needing only very simple equipment. Any old 'scope will do, almost
any bulb will work as a test load, and almost any amplifier will perform at 136
kHz. It remains that one really has to reconsider everything one does. How does an
antenna which is << lambda really work? How do we reduce the QRM to a minimum?

as I said, this happens to be where we live...
