Hello Bryan, Ok, you have definitely shorter cable runs than we do. The cable loss settings may not be as important in your case, but why a split cable on Site A? Twice the chance of connector problems at Site A. Any chance of replacing the two cables at Site A with one LMR-400 cable?
I know this is a basic question, but have you confirmed the cables and all RF connectors are good? What power supplies are you using? I'd also suggest upgrading firmware. We just upgraded ours today: Site A: (trango-view)# ver Current Image Version IDU FPGA version: 00100108 IDU OS version: 2p6r14b3D01110801 IDU FW version: 2p0r1D01110801 IDU PIC version: 18 IDU Modem version: 40 ODU FW version: 07 Previous Image Version: IDU FPGA version: 02080907 IDU OS version: 2p6r14b3D09120701 IDU FW version: 1p0r1D09120701 IDU PIC version: 3 ODU FW version: 07 (trango-view)# cab cable loss at 140 Mhz: 4.45 dB cable loss at 315 Mhz: 6.76 dB cable loss at 915 Mhz: 11.81 dB (trango-view)# Site B: (trango-view)# ver Current Image Version IDU FPGA version: 00100108 IDU OS version: 2p6r14b3D01110801 IDU FW version: 2p0r1D01110801 IDU PIC version: 18 IDU Modem version: 40 ODU FW version: 07 Previous Image Version: IDU FPGA version: 02080907 IDU OS version: 2p6r14b3D09120701 IDU FW version: 1p0r1D09120701 IDU PIC version: 3 ODU FW version: 07 (trango-view)# cab cable loss at 140 Mhz: 5.34 dB cable loss at 315 Mhz: 8.11 dB cable loss at 915 Mhz: 14.17 dB (trango-view)# Best, Brad -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bryan Scott Sent: Wednesday, January 16, 2008 11:19 AM To: WISPA General List Subject: Re: [WISPA] Looking for short licensed link Brad Belton wrote: > If you like, please provide me the cable length and type on each end.
