A recording would be grand. We may have heard something on Friday,
though we're still piecing together what we can expect. If recordings
are made of the times when Prospero is to pass then we can get an idea
of what everyone is hearing now.
On Friday we listened to a complete pass and definitely heard something
different when Prospero was in our vicinity. Whether this was
coincidence with some QRM we don't know. As long as others aren't
transmitting at the same time as us on the Prospero frequencies, we have
a reasonable chance to apply the scientific method to be certain of what
we're listening to.
We probably won't make another attempt till Monday - and we will
probably try the passes at around 1800.
There is information on this on the AMSAT-UK site front page: this
includes the passes we've marked out for definite attempts (we may try
others) and there are some archived recordings of Prospero to compare to.
