[TenTec] Corsair II buzz

[Bwana Bob]

Yes, the magnetic field from the power supply will frequency modulate 
the PTO coil, making received and transmitted signals sound bad.  This 
happened to me when I stacked the Corsair on top of the external VFO and 
power supply. It looked nice but sounded bad.
