It's looking like I might have a chance to travel to Austin, Texas, some ti=
me this summer. There are some great opportunities to record Mexican freeta=
il bats while I'm there (Congress St. Bridge, Bee Caves, etc.) but I don't =
have much in the way of ultrasonic-capable microphones.=0D
We only have one very rare species of bat where I live here in Hawaii, so I=
 haven't had much of a need for ultrasonic mics. I'm more than willing to b=
uild some, but I don't want to pour a lot of effort into a mic I'm going to=
 use for a week, and then not need again for years, if ever.=0D
 While I was looking at some of the capsules Nick Roast has on micbooster.c=
om, a thought occurred to me: I've got all the bits and pieces to build a d=
ual-capsule EM-172 SASS similar to the one Vicki Powys describes on her web=
 If I picked up four EM-258 capsules and either wired them in with the EM-1=
72 caps, or ran a completely separate set of wires, I could potentially bui=
ld a dual-range SASS (20Hz-20kHz on the EM-172s and ???-96kHz on the EM-258=
s). The EM-258 capsules wouldn't raise the cost of the build by that much, =
and in the end I'd still have an SASS I could use in my largely bat-free en=
vironment here once I'm back from Austin. This would also help solve the is=
sue of luggage space since I'm going to Austin for a conference and really =
can't pack gobs of recording gear for the trip.=0D
 My thought is to cluster four capsules for each of the two wings on the SA=
SS: two EM-172s and two EM-258s. I haven't worked through the packing densi=
ties in CAD, but I should be able to keep everything pretty close together.=
 Does this seem reasonable? Or am I barking up the wrong tree with this ide=
