	You presumably are also going to run into another issue,
or more probably NON-issue for that app... Likely the IQ output
that runs continuously is pre-most-AGC and wideband, likely the
stereo one is POST AGC and only +-audio-bw (whatever they chose).
Might make no difference, but depending on the modulation you are
after it might...
