1. [TenTec] Inrad 762 (score: 1): Author: Lee Crocker <w9oy@yahoo.com>; Date: Fri, 6 Aug 2004 05:12:58 -0700 (PDT); I ordered the Inrad 762 a couple of weeks ago. The anticipated arrival time of the filters at Inrad was expected to be the second week in August, so I expect the filter to ship sometime next week.

Since the 1khz filter does an excellent job down to 380 hz, would this not be a better use of the 762? Inquiring minds want; /archives//html/TenTec/2004-08/msg00613.html (7,159 bytes)

Inrad encloses their filters, thus they are a little higher. The filters are in the top section of the Orion, thus have very little risk of wiggling loose.
