James,
I managed to tune this duplexer for 2 meter band with RX loss 1.8 & TX 2.5 db... Isolation was about 78db 73 's SAN VU2CEO, A45WH From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Eric Lemmon Sent: 22 April 2009 05:27 To: Repeater-Builder@yahoogroups.com Subject: RE: [Repeater-Builder] Motorola RFS Celwave 0185417U02 VHF Duplexer James, The Motorola part number 0185417U02 is a Celwave model PD5042-1-50 duplexer that has been optimized for the 144-160 MHz band. It is option X182AB when ordering a duplexer with a Quantar or MTR2000 station. Motorola duplexer 0185417U01 is optimized for 132-146 MHz, and 0185417U03 is optimized for 158-174 MHz. I just purchased this exact duplexer for a commercial VHF repeater, and its performance is awesome- better than 100 dB isolation between TX and RX. I have posted the 11-page manual in the MTR2000 folder in this group's files section. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> [mailto:Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> ] On Behalf Of James Delancy Sent: Tuesday, April 21, 2009 5:16 PM To: repeat...@yahoogroups.com <mailto:Repeaters%40yahoogroups.com> ; Repeater-Builder@yahoogroups.com <mailto:Repeater-Builder%40yahoogroups.com> Subject: [Repeater-Builder] Motorola RFS Celwave 0185417U02 VHF Duplexer Anyone got the spec sheet on this unit?? I am trying to find the original RFS sheet on this (which seems pretty near impossible since EMR acquired the rights to it). Also, does anyone have the actual RFS part number? Thanks! James WJ1D
