I have an R-75 with all the Kiwa mods.
Here's the scenario:
I'll tune to an international broadcast station on AM.
Then, if I switch to either USB or LSB and tune off the frequency either
way,
I'll hear a whine which gets higher in pitch as I move further away from the
center frequency.
Is this normal?
Can SSB only tune an AM station on it's exact frequency?
Thanks


Correct. That's why you have Dual PBT. These let you tune away from
dead center without creating beat frequencies.
