Don't forget they ran L/V (23cm up / 2m down) for a short period in January
Unfortunately few takers, I think only three of us in the UK.

Mode VU suffers from interference at the atellite from illegal use of
2m for taxis etc.
Mode VU has a higher path loss on UHF from the satellite to ground
Mode A has issues with higher noise levels and the size of antenna
required on the satellite.
But, I agree mode A would get a lot of interest from people with HF +
- HF antenna = prototype deorbit system??
or 2 x ferrite rods at 90 degrees on receive
