Yaesu DR-1X C4FM Digital and Analog Hybrid Repeater System
(using Justin Reed NV8Q's script and wiring diagram: Interfacing the Yaesu DR-1X With The SCOM 7330 Repeater Controller)

147.220 MHz (+0.6) PL100.0 Hz in Eagle, MI. (PRIMARY REPEATER)
444.275 MHz (+5) PL100.0 Hz (Not Online: Waiting for Yaesu DR-1X repeater to arrive)

2015-11-27: High winds knocked down my antenna. The repeater
is on a 10' fiberglass antenna in my attic until I get my 92' tower
put up in the spring.

Repeater Commands: 
EchoLink:  To connect:  xxxxx (Simply DTMF the node number. ex: 8126) To disconnect: Press #
WiRES-X:  To connect: # xxxxx (Press # then the node/room number). To disconnect: #99999
Listen to local NOAA Weather: 99 To cancel, press 99 again (or automatically stops after 2 minutes)

Repeater Features:
- It's like two repeaters in one: Analog FM and Yaesu C4FM System Fusion Digital
   - Yaesu C4FM Digital: supports local digital traffic only. Digital users only hear other Digital users.
   - Analog: All controller functions supported in analog only, including WiRES-X, EchoLink, and Weather Alert & Monitoring.
- EchoLink connection: WA8KIM-R, Node 8126
- WiRES-X connection: WA8KIM-RPT (21149)
- DV4mini connection: C4FM FCS001-72
- Weather Alert System (Monitors Clinton, Eaton, Ingham counties via the NOAA WXK81 162.400 Ch.1 Onondaga)
    ( Alarms for Watches & Warnings: Severe Thunderstorm / Tornado / Winter Storm / Blizzard / High Wind / Earthquake / Fire / Civil / Law Enforcement )
- Solar powered.
- Usually linked with my father's K8VEB Repeater which is located two miles west of my repeater.
- Mobile Coverage: Approximately 15 mile radius / Handheld: Approximately 4 mile radius.
- Established on May 8, 2015 using a Kenwood TKR-851. The Yaesu DR-1X repeater replaced the TKR-851 on August 4, 2015.
- In January, 2016, moved main repeater to 147.220MHz. Set up second DR-1X on 444.275MHz.

  • Backup repeaters: Kenwood TKR-851 and Kenwood TKR-820.
The 440.275 Repeater hardware includes (not online at this time: I'm waitng for the Yaesu DR-1X repeater to arrive)
  • Yaesu DR-1X C4FM Digital and Analog repeater, firmware v1.00b
  • 20 watts output (was 49w using the Motorola MSF5000's PA and an ARRA VARIABLE ATTENUATOR 2-3854-20D from eBay).
  • Decibel DB4076w Duplexer
  • Decibel DB420 antenna with a 10.4 dB gain
  • AR2 P432VDG Preamp
EchoLink: I wired a cheap USB sound card to the EchoLink serial adapter. I then wired the adapter to the RLS-1000B. The RLS-1000B and the EchoLink setup are both expecting to connect to a radio.. not each other. Therefore, I had to feed the PTT to COR and COR to PTT between the two, BUT on its PTT, the RLS-100B either grounds the PTT or opens it. The EchoLink serial adapter wants power applied to the SQL/COR line. To remedy this "problem", I used the 2 Channel Optocoupler/relay board listed above. I used one relay for EchoLink and the other for WiRES-X. I ran +12v & ground to the relay board. I placed a jumper from the +12v input to the relay.

I'm not an electronics expert.. I'm sure there's a better way to do this with just an optocoupler (or maybe without any additional hardware), but my setup is working great... "If it ain't broke, don't fix it"

Comment: I added EchoLink to the repeater using the ARS EchoLink Serial Port Adapter. One problem led to another and I ended up purchasing a USB-to-Serial adapter, USB sound card, ground-loop isolating transformers, and an Optocoupler Relay Module to get the EchoLink to work well. If I were to do it all over again, I would have simply purchased a SignaLink USB Interface… it already has the sound card, serial adapter, ground-loop isolating transformers build in with no need for the optocoupler relay.

WiRES-X: I wired the HRI-200 WiRES-X directly to the SCOM 7330 port 2.

SCOM 7330 Programming Script:  WA8KIM's SCOM 7730 Controller Script.txt (Last Updated 2016-02-11 Changed WiRES-X net & 147.220 freq.)
(Contains NV8Q's DR-1X specific code at end of file which I modified: a) Use Port 1 for the DR-1X b) - Changed Logics in and out c) Added a few things to get my CAT WX-250 to work with it)

- The white wire, coming from the lower relay top terminal (hard to see just above the resistor - the 3rd one up), provides (+12v) to the EchoLink Serial Adapter COS pad when active.
- The orange wire, coming from the upper relay, provides (+5v) to the WIRES-X harness when active.

DR-1X SCOM 7330 CAT WX-250 Wiring Diagram
The purpose of this harness is to inject a CTCSS signal to the repeater whenever the WX-250 transmits. The WX-250 does not have a CTCSS encoder.  Without this setup, no CTCSS tone is generated and therefore all radios with receive CTCSS squelch enabled will never hear the weather alert.
