[TenTec] Centering Orion II Roofing Filters

[Bill Miner]

The Elecraft XG-1 or XG-2 mini modules are inexpensive and perfect for 
alignment and checking sensitivity.
XG-1 is 40 meters only and the XG-2 is 80, 40, and 20 meters.  The output is 
selectable between 50 microvolts and 1 microvolt.  The output level is 
stable and very accurate.  (and no computer required!)

73, Bill - K6WLM
