This is my TR7. Recentely I am making some performance tests with my home made mini whip. The design is the classical active antenna PA0DRT. Usually I am using my faitful RX from QRPLabs. The receiving range is from 50khz to 30MHZ. In the Picture, above the Drake TR7 you cam se the antenna preselector. With thermoionic tubes. Bands from 80 mt to 10mt. I am using several SONOFF(WIFI) modules to obtain a sort of remote control. Antenna switching , remote power on off and other functions
Here is our Cumino during his periodic maintenance.

Today I had my best SAT reception at 145.950 MHZ FM. The antenna was o short dipole , this resemble more to Rabbits Ears with a short 300 ohms line in the middle before the radio connector. In fact I stolen it from an old TV set. The idea was capturing an mp3 file , but just few minutes before the sat passage , I realized the I could make a video clip of the all setup.

Today I tried to receive ARISSAT-1 with the minimum cable lenght
from the dipole to the RX.
I Had a good audio for less than 1 min
with the horizontal dipole direction S/W.

ARISSAT-1 QRSS style 13_AUG reception

I am sorry for the terrible quality of the video clip,expecially the audio.
Yesterday's satellite passage was indicate as "good visibility".
I have a lot to improve in my reception setup (IC-R6 + 10 mt dipole).
Before the videoclip processing I was able to identify the audio callsign.
The 600 hz tone ,decreasing while approaching to the max elevation , was well
visible with SPECTRUMLAB.
In any case it was a nice experience !

Here you can follow realtime satellite's postion.

My first ARISSAT-1 reception

Yesterday 10AUG 2011 I did my first satellite reception .
It was ARISSAT-1 deployed from the ISS.

I was lucky to receive with my IC-R6 around 2350 local , his callsign in FM .
The carrier was off for the most part of his fly above my head.

Loud and clear when he switched on his transmitter.
