Heath AR 1-3 And More

[Garey Barrell]

The AR-3 also had a vernier (4:1 ?) on the bandspread knob which made 
the receiver almost useable!

My AR-3 in 1957 gave up it's power transformer, rectifier tube and 
filter cap to power a BC-454. 

MUCH better receiver, even though it was only 80M.   Addition of my 
clock (AC/DC) radio tuned to 1415 kc as a "tuneable IF", (passband 
tuning!) and a BC-453 as a THIRD IF at 85 kc made a pretty powerful 
receiver.   Addition of the QF-1 Q Multiplier to the clock radio (AC/DC 
remember) was an interesting experiment costing several house fuses 
before all the wires got the right way around, adding a regenerative IF 
and notch filter.
