Dear VLF,

It seems these batteries are not in best condition. The carrier got weaker=
 and=20
weaker in the morning and disappeared arround 5 UTC.

The SMPS that drives the PA is designed to generate its own 15 V supply on=
ce it=20
started to run. But if the input voltage falls below 10V (or 9) it shuts=
 down.=20
Seems that this has happend... The batteries have > 300 Ah in sum so it sh=
ould=20
have been no problem, actually...

I assume no one except me has detected anything?

BTW: The starting time was 15:30 UTC so the DFCW shift appeared at 23:30=
 UTC

73, Stefan/DK7FC
