Nando Pelligrini (I1NDP) has upgraded his system hardware and software has now detected 23 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."
