I'm not sure if they are using any low powered transmitters anymore.

I'm not certain either. As recently as a few years back, they were
using something like a 15 or 25kW xmtr on 19m (15425, IIRC), but since
have (1) upgraded to 80 kW or thereabouts and (2) apparently abandoned
that frequency. Now I hear them on 31m using the 80 kW, same
timeframe, coming in *about* as good as they used to around sunset on
the older lower power xmtr. Of course, I was able to hear some Sri
Lankan hams on 20m about the same time as the 19m transmissions, so I
presume that frequency and time was a sweet spot for both the
transmitter, the propagation and the receiver/antenna system (my
DX-Ultra antenna is a honey on 19m, its best wavelength). It still is
a sweet spot for signals from that part of the world to here, even with
the sunspot cycle at it's current near-minima state.
