255.550 MHz which satellite it could be in SEA?

Hello friends, I have sometimes monitored on 255.550 MHz here in Thailand broadcasting in unfamiliar language (may be in myanmar) whole day. Question is which satellite here will cover South East Asia region and who may override this downlink frequency 255.550 MHz? Thank you.

Here is a video I took while riding with an amateur radio friend in Sao Paulo, Brazil listening to Brazilian pirates on a US satellite. My friend listens to them all the time on his ham radio using a simple VHF/UHF dual band antenna on the trunk. It was really cool being in Brazil listening to the pirates and having my friend translate.

I think the other night I counted like 20 something Pirates from 250-270
alot it seems around 263 area ...just using a Discone it really is unreal how
many are on...not hearing the Car Alarm anymore by the way on 257.150,
alot of nights I just copy I guess Brazilian music on some of the frequencies.
73,s Good Holidays and DXing to all...Marcy

266.950....can,t figure that out though somebody dialing and then
weird noises??/ but I,m really not up to all the stuff there thats going
on satellite wise and such but with just a Discone amazing how much
you can cpy...73,s Marcy

I woke up this morning and 266.950 is still going actually louder
than last night does anybody up on this stuff know what it is ?
just wondering ..thank you...73,s Marcy

I had a listen to 266.950MHz this morning and didn't hear anything other than slightly raised noise floor indicating the output of a satellite transponder, maybe a different satellite.......

The satellite you are listening too is not likely not visible in Western Australia.

Likely the same satellite that I can hear, has a very large foot print.

266.950 is still going strong tonight here ....dial tone weird noises ...I was told it might
be a BBS ...bulletin board system maybe????,,73,s Marcy

You are right it is not likely visible here. I will re-align the yagi and see if i can identify the satellite .
I can see a lot of signals in the waterfall, some are very strong while others vary in strength too very weak, so i figured I can see a couple of birds.

I will ask someone at work to translate what the pirates were talking about.

266.950 and there abouts in 12.5 KHz channel spacing are inadvertent uplinks relayed from an old Soviet era mobile phone system. You will hear rotary dialing , ringing, voice. I don't thing the US has a concern as it is a plethora of Intel for US monitoring stations.

If I remember. It has been sometime back now when I used to listen to those Sats. The 266MHz range used to have a number of what were like Russian Phone Type comms. You'd hear Russian voices and dial tones.

My wife understands a few words of Russian, and a while back she heard me tuned in to such a conversation.

A lady talking to a male somewhere, we visualized her in Moscow and he way in the far east boonies, because she kept saying:

"Pochemu?" ("why??").

Perhaps he was telling her his tour of duty was being extended for 6 months (or something worse .....)
