VHF DV RepeaterVHF 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

UHF DV RepeaterUHF 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

23cm DV Repeater23cm 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

23cm High Speed Data23cm 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

Gateway Computer 1 - HWGateway 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

Gateway Computer 2 - HWGateway 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

Internet Feed(s)Internet Feed(s)

We have 2 internet connections:– RF last mile

Fast down, medium upReasonably reliable but subject to wx conditions

– Hotel feed from YVery fast up and downVery reliableInbound ports are blocked (typical hotel strategy)Possible opportunity
