Don't forget they ran L/V (23cm up / 2m down) for a short period in January
2009.

Unfortunately few takers, I think only three of us in the UK.

Hi.

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 + 
50MHz equipment.
- HF antenna = prototype deorbit system??
or 2 x ferrite rods at 90 degrees on receive

Thanks
