[Sbarc-list] Help: Wiltron Model 640 RF Analyzer

Hey:

From the Bill Lake estate (WB6RIJ) we have an item I know less than nothing about.....any ideas on function and/or price would be appreciated.....(and $$ offers also accepted)

Wiltron, Model 640, RF Analyzer, about the size of a Tektronix 7000 series oscilloscope.. I assume(?) it's some form of spectrum analyzer ?? Tnx & 73's Bill W6FF@sbarc.org
