Dear All,
This evening (19th January 2007) at 2222 hours Malaysian Standard Time or
1422 hours UTC, I had a 62 degree pass of Peheunsat-1 over West Malaysia.
As I was in the shack during the pass, I decided to track this satellite
and am pleased to report a successful reception of Peheunsat-1. 
Below are three voice recordings heard on 145.825 MHz +/-:

Unfortunately, the audio level of the 1200 baud packet was too low, and
I did not manage to decode anything.  I have the complete pass recording
in wav format, if it may be of use to anyone.

Equipment used were ICOM IC-910H, 10 Element 2M yagi, SSB SP-2000 Preamp.
Thank you and have a nice weekend to everyone.

Sion Chow Q. C.,
