Hi Greg,

As to your first question.  Make sure you are on the sub receiver  to tune
that 155 mhz freq.   The main receiver will not go that high.    Turn on the
sub rx by pushing in the  knob at  the lower right hand corner of the  front
panel of the rig.   Once it's on, select it by  hitting the  rightmost of
the four  buttons in a diamond pattern  to the right of the  main  tuning
knob.  The tuning knob and keypad will now  work the sub rx which has a
wider freq range than the main rx.  Only am and fm however.

To go back to main, hit the left button in  that  4 button diamond  pattern.


Have fun, 73, Steve KW3A
