As a result of the ongoing QRM - off air noise which is currently triggering the receiver input to the VHF repeater on a continuing basis; I have made the command decision to shut off the DC remotely to the RC210 controller via the APRS MARCAN network (VE1SDR APRS Node).
This was impacting a significant amount of interference to both the VHF repeater frequency and as well to the UHF hard-link being passes on to or repeated consistently to the VHF output at VE1WRC VHF repeater. Even with attempts in changing TX hang time and RX key up delay at theRC210 controller for Sand River did not curb the problem at hand.
As you already know this is not a new problem and has been a real pain now for well over a year (late September 2019) off and on. Even with of a planned introduction of a CTCSS decoder board with the Motorola MSR2000 repeater would still not address the problem of the source of the off air interference which to this day has not been identified.
I am pleased to report Phase One is now completed and the DR-2X VHF repeater 145.190- is now "ON AIR" as of yesterday May 19 2019 @ 4:30 pm.
I thought it more appropriate to install the DR-2X VHF Fusion Repeater project at Salem in two phases as more time would most likely be required to fit it all in just one day.
Phase One Installation (Completed May 19 2019)
Install VHF Multi-couplers in Rack 100
Install RX/TX RF RG-214 coaxial cables from Rack 303 DR-2X VHF Repeater to VHF Multi-coupler Rack 100
Terminate N-Male RF connectors on both RX/TX RF cables at Multi-coupler Rack 100
Install 2RU shelving for DR-2X VHF repeater and 1RU for HP Lap Top computer
Phase Two Installation (Completed June 1st, 2019)
Install HP Laptop WIRES-X computer and HRI-200 WIRES-X modem on 1RU shelving (already mounted) in Rack 303
Install D-Link DIR-819 router on top of IRLP Node 1RU computer in Rack 303 (1RU shelving maybe required if needed)
Install Web Switch 7 near bottom of Rack 303 (3RU blank panel required)
Update IRLP Node 1RU computer static IP information to match D-Link router already configured (Loan of Monitor & keyboard required on time only)
Connect HRI-200 to HP Laptop WIRES-X computer via USB port
Interface HRI-200 to DR-2X VHF repeater (ACC Port)
Set DR-2X from "REPEATER" mode to "WIRES-X" mode
Connect Laptop WIRES-X computer network port to D-Link router network port
Connect Web Switch 7 network port to D-Link router network port
Connect IRLP Node 1RU network port to D-Link router network port
Connect Seaside IP cable to D-Link router WAN port (internet drop)
AC remote outlets for interfacing in order of priority on power up:
D-Link router, HP Laptop, DR-2X VHF Repeater, MSR2000 VHF Repeater, DC power supply, RLC-4 Repeater controller , (AC-DC adapter provided), IRLP Node
Test complete system for both Analog RF operation and WIRES-X internet operation
