What sort of gear does it take to hear a pulsar?
What sort of spectrum are they sending? What frequencies would I listen to?
What sort of bandwidth would the receiver use?
If I have a setup that can hear Pulsar A, will it also be useful for Pulsar B
and C and ...? Or do I need to listen on widely different frequencies?
One problem with pulsars is that they might go below the horizon for part of
Is there a convenient one up near the north pole?
I assume that they are weak enough that I need a steerable dish. Is there a
catalog of pulsars that might be interesting to use for amateur timekeeping?
I assume a strong signal would be the primary consideration.
Any chance of hearing one without a dish?
These are my opinions, not necessarily my employer's. I hate spam.
