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.
