[Hallicrafters] Rf gain Pot for SX 100

[wa1kbq at aol.com]

The RF gain control is most likely reverse log taper and they are hard to find. You will really know it when you have an incorrect one installed. I have several here that have been changed to something other than the original design that need to be fixed.

I need a RF Gain potentiometer for a  Hallicrafters SX 100 receiver. I replaced 
ine with a Precision Controls mil spec pot and it is not the correct taper so I 
eed one from a parts unit if anyone has one.
I am not sure if the RF Gain pot from a SX 99, SX 101or other Hallicrafters 
eceiver of that vintage is the same as the one in the SX 100.
If you have a parts unit, and can part with the pot out of it, please email me 
nd let me know. My discussions with another Hallicrafters owner/technician 
eads me to believe that the RF Gain Pot in the Hallicrafters is an unusual 
aper, NEITHER linear or audio taper.
Please check your stash and parts units for a GOOD RF Gain Pot and let me know 
f you have one for the SX 100. Thanks and 73, John, K5PGW
