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.
