Re: [amsat-bb] Possible AO-40 Beacons!

OK, another update:

435.609.9 MHz modulated carrier still there.  Much weaker, but can still
hear it.  Interesting thing is that the polarization sense has changed to
LHCP.  I can copy it better with my polarity switch flipped.  Don't know why
this would be, particularly if the bird is using the omni antennas.

I did not check the other frequencies at this time.
