Congratulations and well done on some superb logs as usual, especially from

RRI Serui is interesting. I see that it is now moved from 4606.6 to 4605! -
I think reception in U.S. is favoured by the fact that the Serui TX has the
large mass of Irian Jaya mainland behind it and the high mountains. In my
empirical experience this would favour transmission to your QTH as some of
the transmitted signal would bounce off the mountains in your direction.
Received here in Montagu at 2100 utc, bang on local Serui sunrise. Very
faint though and confirms it's 500 watt power. Only managed a very faint RRI
"Radio Republika Indonesia" ID. Signal was barely readable and only came in
for about ten minutes.

OTOH I received RRI Fak Fak also at 2100 utc booming in quite clear with
excellent ID's on 4790 Khz. According to my theory Fak Fak is located on a
large bay with its outlook pointing directly to South Africa and mountains
behind the TX favouring reception in my area. This is also confirmed by the
fact that the signal is so strong here that it gives the impression that the
TX power is much more than the listed 1 Kw, but bear in mind that it is not
received in the U.S. at all.

Why would you say Fak Fak is not received in the U.S. at all? It is reported
here from time to time.

In fact, I believe it is them that I have here at 1200 on 4789.95 or so.

Fak Fak signal still holding up well here, SCI (Song of the Cocoanut Isles) at 1200,
mentions of Indonesia, then into presumed news, and the ocean radar (swisher), has
faded a bit. Like a lot of stations, the voice modulation seems a bit low, but the
music comes through quite well.

One of the better Indo's on the band this morning.

I don't think the mountains have a lot to do with it.

Is there any site/source for the current details on what Over the
Horizon Radars are running and their impact on SWL?

The CODAR transmitters are causing some serious QRM on the tropical
bands in the range 4500-5000/Khz. I've emailed some of the operators,
which are usually universities, to remind them that their transmitters
are disrupting certain international broadcasts. However the FCC
encouraged them to use these frequencies because shortwave listeners are
at the bottom of the barrel when it comes to interference from licensed
stations such as CODAR. The current FCC chairman doesn't seem to care
about the possible interference from the proposed BPL systems, so I
doubt he's concerned about CODAR interference to shortwave listeners.

I get interference on two bands. The high end of 25 meters and the low
end of 22 meters. About as annoying as the Bryant interference on RRS.

I am getting what I believe to be CODAR on two areas of the dial, centered on
these freqs.: 4546 and 4800 kHz. As I am located on Long Island, NY I expect
that these are originating from stations on the New Jersey shore.
