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. --- cheers ... 73 de brian riley, n1bq , underhill center, vermont <http://web.mac.com/brianbr/> Tech Blog <http://www.wulfden.org/TheShoppe.shtml> Home of the K107 Serial LCD Controller Kit FT817 Power Conditioner Kit Tab Robot Laser Tag Kit MSP430 Chips and Connectors Propeller Robot Controller SX48 "Tech Board" Kit On Jul 25, 2007, at 7:34 PM, Scott Miller wrote: >> peak is VERY broad, but the null is very precise.
