Keep in mind also that B0329+54 is really the only one within reasonable "reach" for an amateur in the northern hemisphere--the others are much fainter, although if one simply added another "gulp" of antenna every paycheque or two...
Also, you need a stable clock--I'm using an OCXO, but a TCXO will work for shorter observing times. So, if you are using a dongle, you'll need to replace its clock.

Hi Marcus,Brilliant. I am in the middle of assembling my own radio telescope,but had not thought Pulsar reception would be possible.I have a couple of questions on the RF Hardware. I see from some otherupdates, that the antenna is essentially sets of a 4 bay HDTV antenna.How are you phasing them all together ? Just additive combiners withsame length coax ? What amplification are you using before feedingthem to the SDR ? Or ?Best Regards Iain On 01/12/16 18:45, Marcus D. Leech wrote:
One of the many goals we set for ourselves at the Canadian Centre for
Experimental Radio Astronomy was to successfully observe
pulsar B0329+54 before spring. This pulsar is the only one bright
enough for a small observatory in the northern hemisphere to
observe.
See our update:

The software is available via github:

No custom blocks required--just a modern Gnu Radio install, and ideally,
pyephem.
Doing this with Gnu Radio was so very easy...
