Several years ago, I had an installation of the non-unified chassis system installed at my then repeater site. Since it was wired as a repeater (amateur band) I wanted to be able control it as the FCC requires - so I left the DC transfer module and the line driver cards in the control shelf.
The line PTT worked as the factory had wired it. The remote controlled Private Line Disable latch on the DC transfer module was patched into pin 3 of the Station Control Module (key inhibit) to turn off the transmitter when the need arose. Worked for me. Neil - WA6KLA ---- Original Message ---- From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Can anyone identify this?
