<font size=3>Cory and Group the HRO 500 is
a very temperamental radio. The phase lock
loop loves to just drop out for
no reason... Band switching is difficult
because of this.... De Oxit is for
sure cans and cans needed... Alignment
takes lots of gear and a long
time,,, Almost no one around<br>
that fully understands the radio... I
have had two and sold two will
not own another...<br>
My opinion only....<br>
