This is not the best approach because of the following: when the 50 and 
100 Hz DSP filters are enabled the RX EQ is disabled (I forgot the 
reason for this, but Lyle explained it to me). So the effect of 
narrowing the bandwidth is that the signal suddenly drops several dB!

If you want to use the RX EQ for this the best way to do it is to leave 
the desired bands at 0 dB and *reduce* all others by the amount of 
'boost' that you prefer.
