Norm, Okay, so the frequency band will work for 154 MHz, but now the issue is with the minimum TX-RX separation. The spec is 2 MHz minimum, and you have a 1.3 MHz split. If this were not for a Public Safety application, I'd say try tuning it per the GE LBI and see what you get. It might work, but if the performance was not per spec, I'd recommend going for a new duplexer that is designed for this application.

I was not thinking of moving it down to 2m. I was thinking of using for a fire dept. Repeater that has a 1.3 mhz split in the 154mhz area. Looks like these will not work for this particular ap, but something will come up I am sure.... Thanks! 73 Norm N5NPO ----- Original Message ----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> > Sent: Fri Aug 27 19:06:30 2010 Subject: RE: [Repeater-Builder] Wacom duplexer Norm, The P1 duplexer is specified for 150-162 MHz. Having gone down this path before, I strongly suggest that you send the unit to Telewave for re-manufacturing to your specific frequency pair, which I assume to be in the Amateur 2m band. Unless you have unlimited time, patience, and access to a vector network analyzer, you'll be glad you did. When properly re-manufactured, that duplexer will be an excellent performer. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of NORM KNAPP Sent: Friday, August 27, 2010 4:26 PM To: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] Wacom duplexer Hi guys. I just picked up a set of Wacom duplexers. They have this on them: "REMEC WACOM 344A3371-P1". They may have come with a GE Mastr III repeater some time back and they are VHF. Does anyone have a spec sheet on these? Thanks N5NPO Norm
