Great synopsis Pete! Glad you mentioned the little SW1.

Most of the newer stuff uses glass epoxy circuit boards and SMD
technology, so actually, it isn't bad. Most of the older stuff did not.
I had an Icom 735, and although it was a good unit, the Kenwood 570 has a
better overall receiver. The 735 uses a dual JFET balanced mixer, while
the 570 uses the same type of quad JFET mixer that is used in the Yaesu
FT1000 series and the Racal 6790. The quad mixer has a theoretical IP3 of
+30dBm if implemented properly, while the dual JFET design is typically in
the +15 to +20dBM range. Mind you, this isn't bad.
