>SS-1R
I have owned a couple over the years...the cw filter was pretty poor, and
sensitivity wise it was very mediocre (not really a problem on low bands but
a problem on 15 and 10). It was also prone to IF breakthru...a problem since
there was a strong BC station on it's IF (1 Mhz). But the front end overload
characteristics were strong (7360 mixers) and the AGC very good. I built a
cw filter using 6 1 Mhz crystals from surplus store and then it was a great
cw rx. It had a motor-driven main tuning knob for it's slide rule dial to
QSY between band edges. There was also a matching Panadaptor (never owned
one). One of the coolest exotic ham band rx, along with the Davco (probably
the first serious solid state ham rx), which I wish I still had.
