The rx is not calibrated, nor have I looked at background
variation.  I will set up something to record relative average
background, we can see what the diurnal looks like and pick a
good time from that.

I don't know.  I guess the signal will be detected with some
integration, no problem.  But decoding a message?  Not sure,
your 4mW signal might be about 2 or 2.5fT at Caselle, but we
don't know the background noise.
