No, you can't see the frequency on the Beomaster, only on the Beolink7000.
However, if you know the frequency you're after, you can enter it in four figures on FM only.
Radio Goto 1015 store 7 store = 101.5 FM stored on channel 7
As soon as you press Goto, it should say "F" on your Beomaster.
If you want change to AM, then
Radio Goto Shift Sound then immediately up or down button before it slips back to FM
It should say "A" on the Beomaster..
I am not 100% sure but I think the only two differences between 6500 and 7000 is that
6500 only available in White or Aluminium 7000 also available in Black and mirror finnish
7000 has RDS decoder whereas 6500 hasn't.
RDS decoder is not much use unless you have a Beolink 7000. However, if I remember correctly, Channel name and frequency can be seen on a linked in TV like LX4500. Radio AV Radio Menu springs to mind but don't quote me on that!
