Ham Member Lookups: 7770

 

My start of interest of radio and electronics was in my childhood on the age of 9 or 10 playing with diodes capacitor and coils making a crystal radio.

later I discover the OC13 germanium transistor and added this to my crystal radio.

so I starting reading books about this subjects, over selectivity, detection, AM modulation ect whatever that means.

The crystal radio working so well that it was possible to drive a 800 ohm speaker without a battery supply, the disadvantaged the selectivity was reduced to one radio station.

1 year later i was making radio tube amplifiers and FM (3mtr band) transmitters also experimented on making antennas.

after a view years in 1977 on the age 18 I start with reading exam material and did my exam in begin 1978 and collect my license and my call sign PE1CXV.

My activity  in HAM radio was on the 2mtr band and 70cm band.

My first transceiver was an ICOM-211 and a home-made J-pole antenna, later a I added an 6el Quad for 2mtr band antenna with an rotor system.

after a few years I upgrade my station with an Yaesu FT-726 transceiver and upgrade my antenna system with 4 by 4el Swiss Quad for 2mtr and 4 by 88el for 70cm.

The 4 by 4el Swiss Quad working so well I was able receiving EME (moon bounce) signals

In 1978 I mastered CW and upgraded to "B License" and was issued call sign PB0AIC.

later the authority upgraded the B license to "Full License".

my transceiver for the HF band become an Yaesu FT-102 and a vertical for 10mtr band.

I redesign the 5/8λ with 8 times 1/8 λ radials from the CB 11 meter band to the 10mtr band.

the 5/8 was to short for 10 mtr (LOL) and extended the 1/8 λ radials to 1/4 λ radials.

Later in the beginning of the '90 I become a member of the contest group PI4COM (and still am today ).

I switch my antenna system from the 4 by 4el 2m Swiss quad and 4 by 88el 70cm to an 4el mono Yagi for 10m band and for 2m I reinstall the 6el Quad.

After many years I am still designing, building and trying antenna systems some with good results.

 On the left you see a screenshot during receiving cycle of een 6 meter backscatter, airplanscatter or meteorscatter.

  I have this received on 50.230kHz in JT6M mode on my FlexRadio on the 4el Quad in the direction east.
