hi scott

yes 5 sec is maybe to long but when i change band i have to just push only 
one buttun to tune up
and you still need to look to amp and move band switch, tune and load!
if i move from 15 to 10, amp will be stayed tune on 15m till i push the 
motors are rotating always in same direction and when i tuning  for example 
from 15 to 20
this gonna take 5 sec but from 15 to 10 it´s take only 1 sec!
PTT is loocked when motors are running so i cann start transmiting trough 
amp with TRX  till motors are running
and as soon they stop PTT will be unloocked and amp will serve the power.
next step is to remove amps from the schack!
also everything else like BPF, band switch, tuner etc. is also controlled 
with radio/band decoder!
