HI Kevin, I use Spectra TAC Revievers (such as the C04RTB3108) as Link RXs stack at the same site as the Comparator and I directly wire them in within the same cabinet. In working on systems with these type of voting systems for many customers in the 80's -early 90's, I have found that the levels between receivers are very critical as are the levels between the audio and the status tone. Everything needs to be exactly the same for the Spectra Tac comparator to properly vote the best reciever signal.
For best results use all the same remote recievers as well. Make sure the audio response of all reciever paths are adjusted the same, I use an OP amp circuits to tailor all audio down links to be completely flat across the link. I'm sure you already do that though. 73's, Dan KA0OXH -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of Kevin Custer Sent: Wednesday, January 18, 2006 9:06 PM To: Repeater Builder; Micor List Subject: [Repeater-Builder] Operating a Spectra-TAC Comparator (Voter) without RX encoders. Hi, Need some opinions from folks that may be using the (newer) Motorola Spectra TAC Comparator as a stand alone voter, using RF links that don't transmit all the time. I have some theories on what to do, but I thought I would post to see what others have done. Please be as specific as you can. The comparator I have is the newer style that uses Signal Quality Modules that produce a voltage that corresponds with the quality of the signal received, not the 3 Micor squelch chips.
