Notes:

* Malaysian tv effective radiated powers are probably 10 dB higher than these stated tx powers.

1.  The Limbang tx has two exciters.  It is on one of these frequencies from sign on (~2145 UTC)
and does not switch over during the day.  Both frequencies sound warbly in ssb mode.
Both exciters can show a frequency variation ~100 Hz over days to months.

2.  Cameron Highlands was on one of these frequencies from May 2000 to <Feb 2001

3.  These are educated guesses based on:

 A.the improvement in signal strength of closer txs as the single-hop F2 MUF rises;
