Subject: [amsat-bb:96475] Peheunsat-1 over West Malaysia
From: "Sion Chow Q. C. (9W2QC)"
Date: 2:11, 20 Jan 2007
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 +/-:
http://www.9w2qc.net/peheunsat/voice-1.mp3
http://www.9w2qc.net/peheunsat/voice-2.mp3
http://www.9w2qc.net/peheunsat/voice-3.mp3
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.
73,
Sion Chow Q. C.,
9W2QC.

To All RADIO AMATEURS
BID: $ANS-028.05
http://www.amsat.org/amsat/ftp/news/ans.new
Engineer Jorge Lassig, director of the Penhuesat Uncoma project informed
amateurs that the satellite takes between 48 and 72 hours to charge its
batteries, due to the inadequate position of the nosecone to which it is
still attached in reference to the sun. Once the batteries are recovered,
the satellite transmits during several orbits until they discharge again
causing the onboard computer to set the system in safe mode, leaving just
the oscillator on. Folks at Uncoma are evaluating when the nosecone will
change its position in space to improve the battery charging process of
Penhuesat.
