Re: [Discuss-gnuradio] Probable pulsar observing success at CCERA

[mleech]

This is 6MHz, centered at 611MHz (a notionally-TV channel that is allocated in North America and Caribbean to Radio Astronomy).

I used a PFB channelizer with individual detectors, and then delay adjustment after the detectors and then simply added, low-pass filtered, then resampled to a precise multiple of the current topcentric pulse rate.

That's awesome work!  Thanks for sharing it.  How much bandwidth are you observing and did you also use de-dispersion?

One of the many goals we set for ourselves at the Canadian Centre for Experimental Radio Astronomy was to successfully observe

See our update:

The software is available via github:

https://github.com/ccera-astro/pulsar_pfb _display

No custom blocks required--just a modern Gnu Radio install, and ideally, pyephem.

Doing this with Gnu Radio was so very easy...
