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 
the day.

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.
