As an update, I recently got a bounced e-mail which was sent to Jerry so I think he may have left Motorola. I know he was doing a lot of missionary work so he may be doing that exclusively now.
I was browsing the forums and spotted this old thread. I got a note from Jerry by e-mail recently so I thought I'd update it.
Jerry has been helping here on and off for years and I (and many others) appreciate Jerry's help. Jerry is with Philips Medical Systems now and continues to help out in the calibration forum when he has time.
