Hi Gary,

on DL4YHF's HP you'll find some info about the IC706 (first version,i.e. no MK1 
nor Mk2)
on 630m.
http://www.qsl.net/dl4yhf/mf/mf.html#IC706_on_MF
It would appear that all three versions of the 706 behave quite identical on MW.
My 706/Mk2's output signal on MW looks like Wolf's 706 signal on the scope.
