QF-1 FS

[Ken Simpson, W8EK]

For Sale:

Actually, I have two very different QF-1's for sale.  One is 
the Autek QF-1 audio filter, and the other is the Heath 
QF-1 "Q multiplier".

Autek QF-1 active audio filter
This is an audio filter that goes between your rig and 
speaker. It runs off of 110 V AC, and will peak, notch, 
or become a low pass filter. Selectivity (bandwidth) 
and frequency are adjustable from the front panel. 
The input is a 1/4 inch phone plug, and the output is 
a 1/4 inch jack on the front panel. This particular unit 
looks very good, and works the same. Paper work
is included for $40.

Heath QF-1 "Q multiplier"
This unit attaches to a receiver to improve selectivity. 
Memory says that it needs a 455 kc IF. The styling 
matches the DX-60 / HR-10 rigs and others of that era.
There are a few scratches on the case. $10

Prices do not include shipping from Florida.

Thanks.

73,

Ken, W8EK
