Voice and Packet heard from ISS on 145.825 MHz
This audio was recorded during a 10 degree elevation pass of ISS over New Delhi at around 13:22 UTC (18:52 IST) on 02.02.2009. My antenna was a vertical gp. I could hear Russian voice on 145.825 MHz followed by simultaneous 1200 baud packet burstsin-between voice. Was this the voice [ heard on 145.825 MHz] of ISS Flight Engineer Yury Lonchakov, RA3DT?

Here is the recorded file (in mp3 format) of the HAMSAT
(Indian ham satellite:
VUSAT) aka VO-52 beacon. I recorded it on November
17, 2005 (23:00IST/17:30 UTC) while adjusting to the Doppler Shift (on 145.865 MHz). Antenna was a 7/8 lambda collinear stacked
vertical (Diamond SG 2000 Japan) and rig was FT 290R-II
was totally buried in the noise. The Beacon CW message reads like:
"This is VUSAT nw with the Dutch mode
UV transponder made by William Leijenar 73 de PE1RAH HI HI HI"
Listen to VO52 beacon (duration 5 minutes 54 second)
There are three CW "laughter" (HI), then the message repeats again.
It is said that CW (Morse Code) has an advantage of approximately 20 dB
over SSB. When the band appears
to be dead, when we can barely copy phone signals, the band still remains alive with
exotic sounding CWs!
