For this once every few years attempt, it is not really anyone's fault that
they may have not seen the bulletin to stop transmitting.

I did just find that his APRS home station is showing his email address, so
hopefully now he will get my message.

Thanks, Bob, WB4APR

Almost recovered.  Mike got command over Germany (DK3WN) but it did not
hold.

At 1300z pass over east coast,  I got 3 telemetry packets, 5, 6 and 8
minutes into the pass with Latitude between 29N and 39N.  The first packet
showed +Z (best panel) current was 93 mA.

Above that latitude, packets got weaker.

One person got a perfect digipeat just about when I was going to try to
command at 7 minutes into the pass.  So I waited 1 minute and tried to
COMMAND at 8 minutes into the pass, but it killed it.  No response after the
first ACK.

TLM did not appear again until 10 minutes into the pass.  But +Z current was
down to 59 mA.  Only decoded that one packet for the rest of the pass.

WE MUST GET EVERYONE TO STOP TRYING TO DIGIPEAT.  Chances are, that one
successful user packet should have been mine for control, it was at the
right time, and best sun angle.  It used up all the power and so I had to
wait another minute, but by then the power had dropped.
