[amsat-bb] Cease PCsat OPS for today please

[Bob Bruninga <bruninga@xxxxxxxx>]

Please cease PCSAT transmissions today.

PCsat reset overnight over Europe and we are trying to get it back into
low-power conservation mode.  We will try hard for a day or so, and so it
will be nice if everyone goes QRT to give us a chance to get back into
positive power budget.

Thanks.

Here is the chronology:

> 01 Jan 2003:
>  at 1917z still OK as     PCSAT-1 #344  00111111 Over EUR in Dark
>  at 1945z had reset to    W3ADO-1 #002  11111111 First light after Europe
>  at 2124z had reset to    W3ADO-1 #001  11111111 First Light after Europe
>  at 2145z VK2XGJ restored PCSAT-1 #021  00111111
>  at 2220z it was still    PCSAT-1 #056  11111111

> 02 Jan 2003:
>  at 0012z it made it to   W3ADO-1 #068  11111111
>  at 0048z it RESET  to    W3ADO-1 #001  11111111 First light after Europe
>  at 0154z it made it to   W3ADO-1 #066  11111111 volts were 150/151

*  at 1230z W4EPI Atlanta reports sigs too weak to connect in dark
