[ARC5] Lopsided modulation

    Depends on weather you mean unloaded, where the Q may be very 
high, or loaded, as with an antenna connected and tuned. The 
loaded Q may be very low since the resistive part of the antenna 
impedance is imposed on the circuit. The loading is why the plate 
dip becomes so broad as the loading comes up to its working 
value. Along with the effective Q becoming lower the bandwidth of 
the final tank becomes broader. In general, if the grid and plate 
tanks have been tuned to optimum they are tuned to the carrier 
and will not discriminate sidebands or even be narrow enough to 
do so.
