It had major short comings. SSB and CW were crudely heard by tuning with a "sensitivity" knob. I couldn't find an external BFO add on because it used a 1650 IF instead of the common 455 IF. Selectivity was marginal.
Short comings aside, what a great gift from my grandfather when I was about 10 years old and listened to for about 6 years or so.
Thank you Grandpa.
