  Recently I learned how important electrical contact
at these screw points is.
 I had low speaker output and I thought the band
conditions were the reason. I noticed at some point that
in picking the K2 up from the left side, the volume
increased and the leftmost LED on the signal strength
meter disappeared. I removed the bottom panel and on
screwing it back with power applied, turning the screw
created electrical noise. I worked it back and forth
until the noise disappeared and now the K2 is much more
sensitive and louder.
  With no other K2 to compare, I hadn't realised there
was a problem.
