Alan Kung, BA1DU and CEO of CAMSAT was one of the speakers at the Dayton AMSAT Forum.  He reported that HO-68 is suffering from a bad relay or relay driver that is used to switch from the beacon to the transponder.  The likelihood of recovery is low, but not zero.  

Here is the explanation from Alan's slide.  These are exact quotes, not my interpretation:
-- The current situation is the transponders will be difficult to switch the RF PA from beacon mode to transponder mode

-- The RF relay or its drive circuit is failing, it is a stick relay.  Probability of success of switch is probably a few tenth

-- On the other hand, up to now the both solar and lithium-ion batteries are in very nice condition

-- The exhibitions of the thermal-control, onboard flight computer and TT&C are also excellent.

Can anyone give me an update as to the statis of HO-68? I used to be able to access the web site,but can't even do that now? I know the Bcn is working but what about the rest of the bird? I seemed to have missed something somewhere? 

Thanks! Ellis
