This Hammarlund HC-10 Super IF and Audio System, provides SSB reception and greater selectivity for receivers without a product detector.

This one is in excellent cosmetic condition. I powered this unit up with no problems and all the tubes light up okay.

I have not used it with a receiver.

 It does require an interface cable and it is a simple assembly you can make one up easy as outlined in the manual which is included. This plugs into the last IF tube in your receiver.

This unit basically is a full receiver that uses the panel controls of the receiver it is being used with.

I am selling it as is as described for the family of a silent key who was my friend.
