Wow, John!
Way cool, indeed.
Thanks so much!

The sagebrush rocks.
I gotta try that one for sure.

I could go with mono, although I have lavalier mics I could try for the ste=
reo thing.

How wide is the Telinga dish?

I thought about a homemade job using a 14" "wok" lid.

However, that might be dangerous territory.
Either way, I need something I can use for several things, so the dish or t=
he shotgun might have to be it.

Thanks so much for all your help.
Do you have a Kindle book reader?
