That is what I was thinking as well. Perhaps if I had two more small cans the size of these.... Oh well.... Needs to be small to fit in 36" tall outdoor cabinet with TKR-751 and able to provide needed isolation at 50w for a 1.315 (to be precise) split... As for now it is no big deal. This TKR-751 is a remote receiver (tx frequency left blank) connected to a tk-862 for uhf link to a voter.. It could be a back up repeater however in the event of an emergency where the main repeater was down if there were a duplexer in the cabinet.... BTW, has anyone heard that Doug Hall was getting out of the voter business?
Thanks for your input as always Eric. 73 ----- Original Message ----- From: [email protected] <[email protected]> To: [email protected] <[email protected]> Sent: Fri Aug 27 22:33:16 2010 Subject: RE: [Repeater-Builder] Wacom duplexer 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. 73, Eric Lemmon WB6FLY -----Original Message----- From: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> [mailto:[email protected] <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of NORM KNAPP Sent: Friday, August 27, 2010 6:35 PM To: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> Subject: Re: [Repeater-Builder] Wacom duplexer Hi Eric. 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....

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: [email protected] <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> <mailto:Repeater-Builder%40yahoogroups.com> [mailto:[email protected] <mailto:Repeater-Builder%40yahoogroups.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: [email protected] <mailto:Repeater-Builder%40yahoogroups.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
