tried searching but no definitive answer here to the question:
What makes a boat anchor?
i have thinned the herd over the last several years of R75s, SGC SG-2020s, ICOM 703s, RS 394, Lowe 225, Europa, TS-570D, my Ten Tecs (Argo V, VI, Jupite)r, FT-857, 897 and so on...
i now use more modern rigs w/waterfalls, SDR, etc.
my personal criteria is that a rig is a boat anchor when 1) the manufacturer goes out of business 2) the rig is discontinued with no parts availability and 3) when LIDs try charging outrageous prices for used gear
