Does anyone in the group own either a crystal or regenerative set?

Yes, both.

How are the regeneratives sets on the BCB comparable to say a regular
just AM radio. Can you actually get some good dx from one of them on
his site? TIA

Regenerative set characteristics:

Very sensitive. Poor selectivity. Subject to tuning instability from the
"hand-capacity" effect. Not a 'good neighbor' to other radio receivers
in the neighborhood due to radiation back through its antenna.

That is not a problem here. :-)


These
negative characteristics could be somewhat mitigated by some design
tricks, but almost any superheterodyne will run circles around a regen.
To (sort of) answer your question about DX -- it has plenty of
sensitivity, so OK for DX -if- selectivity is not an issue. They were
great in their day (the 30s) because they could be built cheaply (not
many disposable $ during the Depression), there weren't that many
stations around nor very many 50 kW blowtorches. A good receiver for its
time, a technological curiosity today.

So I couldn't grab BCB DX from say Kansas/Nebraska from here in Ohio?
I am somewhat familiar with the regenerative sets I suppose. My
Hammarlund 129X has the Heathkit Q Multiplier add on, isn't that
somewhat comparable? The use of the Q Multiplier I mean. I lover the
129X but it just wouldn't be the same IMO without the Multiplier.

What would be the best type of antenna for one? Antenna wise isn't it
basically the same as connecting to any other radio? Or is a specific
type of antenna better. TIA
