[Test-Equipment] Hickok signal generator

[Carl]

One limitation of the 288X is the lowest frequency is 100 kc which 
eliminates several Halli, Hammy, and National receivers with their low IF's.

For simply sweeping higher frequency filters I suppose a varactor pulser 
could be used with selectable ranges and rates.
