[R-390] R-1051

[Steve Hobensack]

I use an R-1051b as an auxilary rx in the ham shack. When changing bands, is 
it better to move the mode switch to the standby position, before changing 
bands (mhz)? The motor doesn't start and stop as much, but it puts more 
ware/tare on the mode switch. Is there a better procedure for changing 
bands?
