Homepage von Bernd DL7APV Pulsare detection

Mit dieser großen Antenne kann man nicht nur EME machen, sondern auch ein wenig Radioastronomie!

With this huge antenna not only EME is possible, but also a bit radio astronomy!

 

JO62jr 40m asl.

 

Setup is here the 432 MHz EME Antenna on main page

128x11el. H-Pol. with

35,85 dBi gain @432MHz

Tsys=97K

RX RTL dongle V3

2MHz BW

 

TNX to OE5JFL, PA3FXB, IW5BHY and I0NAA I could detect a few pulsars

See for basics and more:

http://neutronstar.joataman.net/  and

http://i0naa.altervista.org/  and

http://iw5bhy.altervista.org/  and

https://www.qsl.net/oe5jfl/pulsar/pulsar.htm

First attempt in 2018: B0329+54 was detected within only 200sec.

The B0329+54 is the strongest on 432 in the northern hemisphere!

With longer integration time this pulsar could be seen even with very small antennas!!!

 

Detected were currently 24 pulsars, but I hope the number is growing with more experience

In 2020 I had to use an offset of -32ppm at my SR error to get good results, but I don’t know why?
