Hello,
recently I received some additional audio recordings and could thus
complement my "Sounds from Space" collection of satellite signals.
Many thanks to Rolf DK2ZF and Dave WB6LLO for providing their recordings.
You may have a look at www.dd1us.de at "Sounds from Space" and enjoy

Hi Luc,
a linearly polarized antenna on a satellite means, that you will see
different polarization at different times and different locations on
Earth. Assume the satellites transmit vertical polarization but "tumbles"
then the polarization you are receiving is always linear but can vary
between

Hi Zack and Domenico,
I would like to add, that the negative effect of the added losses in front
of the preamplifier and thus reduced sensitivity of your system is also a
function of the noise level: in terrestrial systems where your antenna
typically sees a noise temperature equal to the ambient

Hi Mike,
ich hatte heute Nacht den Empfänger mitlaufen und neben packet radio
signalen waren auch andere Störungen hörbar, die wie Rückkopplungen klangen.

Very nice copy of ARISSAT-1 on 145.950 MHz in Germany JN49QF at 20:28 UTC.
Satellite had strong signal until it switched off during the pass and did
not come back before LOS.

thanks for the hint. I contacted Bent and he was kind enough to provide me
several recordings. I am presently adding some of them including recordings
of the early RS satellites to the "Sounds from Space" collection.
I will upload the update shortly.

Hi Grahma,
I like your idea ... to receive signals at VLF which cannot be heard on the
ground and convert them to a frequency band which we can receive ... I guess
this will allow us to receive some "sounds from space" which we are
otherwise blocked from ...
