  1. I had one about 15 years ago, I do not recall it being very sensitive, but it was different in its mechanical tuning mechanism and availabile crystal control; a glorious receiver!

I will not part with them for any amount or offer or consider any trade for modern equipment. They have no equal, except maybe for the Collins R390-A, which is another amazing receiver in its own right.
