uThe band-pass filter
was moved from behind the second amplifier to behind
the first amplifier.
Basically the signal
coming into the amplifier is too large. The amplifier can only handle a gain
of about 70 dB. It becomes saturated, heats up and suffers a lost in gain.
RFI is created when this happens. Carl hopes that by moving the band-pass
filter the signal can be attenuated to some degree. Carl only worked on the A
channel.
