9 Antennas – 23cm High Speed Data
10
10 The Equipment Cabinet
11
11 VHF DV Repeater Standard Icom ID-RP2000V May benefit from internal cable upgrade May benefit from PA to increase power to 100W but maintenance issues increase
12
12 VHF Filters
13
13 UHF DV Repeater Standard Icom ID-RP4000V May benefit from internal cable upgrade May benefit from PA to increase power to 100W but maintenance issues increase
14
14 23cm DV Repeater Standard Icom ID-RP2V May benefit from internal cable upgrade May benefit from improved receive pre-amp Would benefit from added external filtering
15
15 23cm High Speed Data Provides 128kb data Standard Icom ID- RP2D (contains ID-1) This is a simplex function like wi-fi Clear path between antennas is essential Users should use small yagi (vertical) or helix User should be stationary, mobile doesn’t really work
16
16 Gateway Computer - SW OS is CentOS5.4 (linux) Application Software – Icom G2 – dPlus – MonLink – dPlus report – DPRS – Icom Apache (httpd) – Standard Apache (httpd) – ircDDB – dextra

17 Gateway Computer 1 - HW Shared LCD screen IBM Thinkcenter S50/S51 SFF – CPU Intel 2.8GHz Pentium 4 – Memory 1024MB PC-3200 – HDD 80GB SATA – Video On board Intel 82915G – Sound On board Soundmax – USB 8 x USBv2 – Optical DVD-ROM – Eth0 On board Gigabit Broadcom – Eth1 add-on 10/100 – Serial Com1, Com2 – Parallel LPT1 Good machine – may benefit from more memory
18
18 Gateway Computer 2 - HW Backup machine to #1 Shared LCD screen Homebrew Tower w Intel D850 MB – CPU Intel 1.7GHz Pentium 4 – Memory 512MB – HDD 160GB SATA WD1600JB – Video GeForce MX4000 128Mb 3D – Sound On board – USB 4 x USBv2 – Philips CD/DVD R/W – Eth0 On board – Eth1 add-on 10/100 – Serial Com1, Com2 – Parallel LPT1 Adequate BUT should be replaced with same as machine #1
