CHINA is not too far....

2011-09-23T04:19:00.000-07:00

From South Italy on board of LEONARDO (oceanographic vessel) I recorded this emission.
RX time was around 06:30 UTC , antenna 7mt wire referred to the Hull.
You can hear in the background the propulsion noise.

ARISSAT-1 18_AUG 1845 UTC LIVE RECEPTION

2011-08-18T13:32:00.000-07:00

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.

SUMMERTIME SAT HUNTING

2011-08-16T12:49:00.000-07:00

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

2011-08-14T02:21:00.000-07:00

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

2011-08-11T02:37:00.000-07:00

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.

IZ1KXQ SOLAR MEPT (tone)

HOME MADE ROTOR

2009-04-24T13:17:00.000-07:00

This is my first tentatives for my HF indoor magnetic loop project.

This is my 5mW SOLAR MEPT today.
It is triggered every minute from the reference
station DCF77. The signal has a shift about 10HZ
and remenber a camel when the strenght is enough.
In the picture the antenna is not connected (50 ohms dummy load).
My DSB receiver picks it very well even on this conditions.

DCF77 WORLD

2009-01-23T04:57:00.000-08:00

Modifying my 100% Chinese alarm clock , I discovered an interesting world.
At the frequency of 77.5KHZ is tranmitting the VLF station DCF77.

Capturing the tiny time digital code (0-1.5V) , by an optoisolator
I made a qucik sincronization with a microcontroller PIC16F84.
I was able to extract one pulse per mitute , necessary for
triggering my 5 mW SOLAR MEPT.

2009-01-18T14:33:00.000-08:00

Today with a new setup of my SITECOM WL-601
I gained a faster connection speed 6.8 Mbs/sec.
I reduced The "Beacon Interval" to 20 msc
in the wireless section.

Changing field.
Here is showed the first nice report
of my solar mept , thanks to Peter PA1SDB

2009-01-10T10:20:00.000-08:00

A new era started today , after a fantastic speed increase
of my internet connection compared with my previous 5okbps modem.

I hope to be more "internet active" this year compared with 2008.
I lot of micro projects and ideas are going to be published by me.

My SOLAR MEPT source of energy

2009-01-10T09:37:00.000-08:00

The power source is the 4x4 cm photocell in this picture.
Up to now I was able to transmit 5 mW max
on 30 mt dipole , into the roofspace.
I receive daily RX reports of it , at 1000 km.

IZ1KXQ PRESENTATION

2008-02-28T04:28:00.000-08:00

Hi all my name is Paul , I am an electronic engeneer and radiomateur since 2005
always interested on low power radio techniques.
On this Blog you can find some bits of my experience.
A lot of projects , never finished but sometimes failing and evolving somethimes.
Motor of all is my curiosity on the radio world.
