KO-23 eclipse-less


KO-23 has entered another period of permanent sunlight; looks like it ends
on 28 November.

For newbies: this causes the spacecraft temperature to rise (because there
are no eclipse periods in which to cool off). The higher temperature brings 
on a known fault in the transmitter whereby the fm deviation increases and
so stations with narrow filters in their receivers will experience degraded
reception (strong carrier but little or no data received). 

Theres a second transmitter on-board (same frequency) but, in the past,
when requested, KAIST have not changed transmitters. Speculation: perhaps
its faulty and they don't want to admit this.

I thought these only happened every five months but they seem to happen
more often lately.
