Glenada Hill Yaesu C4FM UHF Repeater Features & Settings
IMRS (Internet-Linked Multi-Site Repeater System):
Currently our Glenada Hill UHF repeater system can be linked to a similar repeater which is operating in Coos Bay
on 147.320 MHz under callsign K7REA. The link is controlled by the DG-ID setting in your radio and the audio link
is completed from our repeater thru the internet to the repeater in Coos Bay. While this link is active any digital
C4FM user in Florence can communicate with other digital C4FM users in the Coos Bay area. Once established the
link remains open for thirty (30) seconds from the end of the most recent digital transmission.
There are some informative beepsthat occur as follows:
1 beep: Connection to remote repeater established
2 beeps: Link has been dropped
3 beeps: Connection failed on one or more repeaters
Additionally, we have a third repeater (Sherwood) which can be accessed during our testing phase. This repeater is
actually located SOB at AC0WN’s QTH and will eventually be installed in Sherwood, OR. The Sherwood repeater is
on a test frequency pair at 440.275 +5mhz
To use the IMRS system you set your transceiver’s TX DG-ID as follows:
Florence Repeater Only: 00
Florence Repeater and Coos Bay Repeater: 02
Florence Repeater and Sherwood Repeater: 03
All linkable repeaters (currently 3): 99
IMPORTANT: Once you are done with the link please remember to return your transceiver’s TX DG-ID back to 00.

Overview

This document provides a comprehensive guide to the Glenada Hill Yaesu C4FM UHF Repeater, detailing its features, settings, and operation within an Internet-Linked Multi-Site Repeater System (IMRS) and for WIRES-X functionality. The manual covers configuration procedures for several Yaesu transceivers, including the FT3DR, FT2DR, FTM-400, and FTM100D.

Function Description:

The Glenada Hill Yaesu C4FM UHF Repeater serves as a central hub for digital C4FM communications, enabling local users to connect with other amateur radio operators over a wider area. Its primary function is to receive digital C4FM signals and retransmit them, extending the range of handheld and mobile transceivers. The repeater is integrated into an IMRS, allowing it to link with other repeaters via the internet, specifically with a repeater in Coos Bay (K7REA on 147.320 MHz) and a third repeater (Sherwood) currently in a testing phase at 440.275 +5MHz. This internet linking capability facilitates communication between C4FM users in different geographical locations, such as Florence and Coos Bay. The link, once established by a digital transmission, remains open for 30 seconds after the last digital transmission.

Beyond IMRS, the repeater also supports WIRES-X, Yaesu's internet linking system, which allows users to connect to various WIRES-X rooms and nodes worldwide. This dual functionality provides operators with flexible communication options, either through the IMRS for regional links or WIRES-X for broader global connections.

Important Technical Specifications:

  • Glenada Hill Repeater Frequency: UHF (specific frequency not provided, but context implies it's the primary repeater for Florence).
  • Coos Bay Repeater Frequency: 147.320 MHz (VHF).
  • Sherwood Repeater (Test Phase) Frequency: 440.275 MHz (+5MHz offset).
  • Digital Mode: C4FM (Continuous 4-level Frequency Modulation), a digital voice mode used by Yaesu.
  • Linking Mechanism: Internet-based for IMRS, controlled by Digital Group ID (DG-ID) settings.
  • IMRS Link Timeout: 30 seconds after the end of the most recent digital transmission.

Usage Features:

IMRS Operation:

Users can select different linking configurations by setting their transceiver's TX DG-ID:

  • 00: Florence Repeater Only (local operation).
  • 02: Florence Repeater and Coos Bay Repeater (regional link).
  • 03: Florence Repeater and Sherwood Repeater (test link).
  • 99: All linkable repeaters (currently Florence, Coos Bay, and Sherwood).

The system provides auditory feedback through "beeps" to indicate connection status:

  • 1 beep: Connection to remote repeater established.
  • 2 beeps: Link has been dropped.
  • 3 beeps: Connection failed on one or more repeaters.

WIRES-X Operation:

To access WIRES-X through the Glenada Hill repeater, users must set their Wires-X DG-ID to 70. This setting is distinct from the GM DG-ID used for IMRS. Once the Wires-X DG-ID is set to 70, users can engage WIRES-X by pressing the red "X" button on their radio. The duration of the button press varies by model (quick press for FT2DR/FT3DR, ~2-second hold for FTM-400).

When WIRES-X is active, any digital C4FM radio in WIRES-X mode on the correct frequency can transmit and participate in the WIRES-X conversation. Radios not in WIRES-X mode will hear both WIRES-X and local repeater traffic, but their transmissions will only be heard on the local repeater, not via the WIRES-X internet link.

Transceiver-Specific Configuration Guides:

The manual provides detailed, step-by-step instructions with accompanying images for setting TX DG-ID (for IMRS) and Wires-X DG-ID (for WIRES-X) on the following Yaesu transceivers:

  • FT3DR: Handheld transceiver.
  • FT2DR: Handheld transceiver.
  • FTM-400: Mobile/base transceiver.
  • FTM100D: Mobile/base transceiver.

These instructions typically involve:

  1. Pressing the "GM" or "DISP" button for a specified duration (e.g., 2 seconds).
  2. Briefly pressing a soft button (e.g., "GM" or "Wires-X").
  3. Turning the DIAL to select the desired DG-ID value.
  4. Pressing the "BACK" button one or more times to exit the menu and save settings.

Maintenance Features:

IMRS DG-ID Reset:

A crucial maintenance reminder for IMRS is to return the transceiver's TX DG-ID back to 00 once the user is finished with the linked operation. This ensures that the repeater defaults to local operation and does not unnecessarily maintain an internet link.

WIRES-X DG-ID Persistence:

The Wires-X DG-ID setting of 70 can be left configured as a "set it and forget it" step when primarily using the local Glenada Hill Wires-X node. However, if an operator travels and uses other Wires-X nodes, they will likely need to return this setting to "Auto" to ensure compatibility with different node configurations. This highlights the importance of understanding local vs. global settings for optimal operation.

The document emphasizes the importance of not allowing IMRS traffic on the Wires-X network, indicating a design choice to separate these two linking systems for efficient operation and to prevent unintended cross-network communications. This separation is managed through distinct DG-ID settings and activation methods.
