Pulsar Observations: Phase 2 - Nando Pelligrini (I1NDP)

Nando Pelligrini (I1NDP) has upgraded his system hardware and software has now detected 22 pulsars using a 10 metre dish @ 1296 MHz.

Improved 23cm System Pulsar Observations

Nando writes..

"After the first experience with pulsar B0329+54 I gave up because the increasing number of interference on the 23cm band reached such a level that was not compatible anymore with my setup.  The limitations were mainly the narrow available window due to the filters inside the transverter with 4Mhz bandwidth and also my Perseus SDR with its 2Mhz max sample rate did not allow a high sensitivity in pulsar signal detection.  The next big limit was my home made software far removed from the sophisticated algorithms used by professional observatories.  The original setup was therefore deeply revised, as much as possible, in terms of receiver chain and data post processing."

Nando acknowledges the assistance of OE5JFL (Hannes), I0NAA (Mario) and IW5BHY (Andrea) with various aspects of his upgraded system.

The Results (2017)

"The following is a list of the already observed Pulsars with a link to specific pulsar data and graphics. The graphics are composed by the full Presto output plus a zoomed view of the pulsar profile. The pulsars are listed in decreasing flux intensity order (which is measured in mJansky )and therefore in increasing order of difficulties for their detection which means in any case being able to detect few thousandths of db signal out of the noise:"
