iN nWVT we add a little to that technique. We use paper clips opened
up and cut into 1", 2", and 3" lengths and when we get to a point
that where ever we go is full scale we take off the antenna and
insert the 3'' until its full scale and then on down to 2", 1", then
nothing and use body block. Three years ag we had a club project and
we built active attenuators with 2 MHz crystals and that also works
pretty well, better than the 5KHz off technique ... but its no good
like say at the Fox hunts at the Dayton Hamfest with all that QRM.
