Hi Bob.
> Drats. Bad news.. Good news!
I don't think the ionosphere will allow 160 meter downlink propagation... on a
regular basis, at least.
UoSAT-OSCAR-9 carried HF beacons on 7, 14, 21, and 28 MHz, and if I recall
correctly, the only beacon never heard was the one on 7 MHz.
So, receiving might be more beneficial than transmitting. It might prove
interesting to have the satellite generate a spectrogram of received signals in
the form of a GIF image that could be downloaded from the satellite, thereby
eliminating the requirement that the receiver's input be within a satellite
sub-band. ;-)
A spectrogram plot covering a whole orbit might also prove to be very
interesting. It might answer questions such as: Can sferics from lightning be
received outside the ionosphere? What does the VLF spectrum look like over the
poles vs. the rest of the globe? How does solar activity and auroras effect
VLF energy above the ionosphere? Can energy from the 50/60 Hz power grid be
received in space?
