Heathkit SB-101 - Page 4

An 11 megohm input VTVM, such as the Heath Model IM-11 , (a 20 K /V VOM may 
also be used)..................................................................................................................32
A 50 nonreactive dummy load that is capable of 100 watts dissipation, such as 
the Heathkit Model HN-31. Do not use light bulbs as a dummy load, as their
resistance varies radically with voltage......................................................................32
A receiver capable of receiving WWV, such as the Heath Model GR-54, at 2.5, 5,
10, or 15 MHz. If this type of receiver is not available, a receiver tunable to a
standard broadcast station that is operating at an even multiple of 100 kHz (such
as 600 kHz, 1000 kHz, etc.) can be used......................................................................32
