Repeater System Term of Use

The fine print...

Table of Contents

Article 1 – Scope

The following articles shall apply to all persons intending to operate the repeater systems associated with Tucson GMRS Association, Inc, conducting business as the “Southwest Community Radio System,” hereafter referred to as the ‘SWCRS’ and ‘REPEATER SYSTEM’ respectively.

The rules and regulations posted herein and imposed by the SWCRS are subject to change at any time without notice.

Article 2 – System Owners

The REPEATER SYSTEM consists of privately held equipment from numerous entities (‘OWNERS’); ownership information for specific repeaters and associated equipment may be requested by any authority having jurisdiction by contacting:

Article 3 – Usage Requirements

In exchange for being permitted to use the system, all control operators (henceforth known as ‘CONTROL OPERATORS,’ ‘OPERATORS,’ or ‘USERS’) enter in agreement with the OWNERS the use of the REPEATER SYSTEM; USERS agree to operate in compliance with the following rules:

  1. Abide by the FCC’s rules pertaining to the General Mobile Radio Service.

    Commentary: You need a GMRS license to use this service, no, a ham radio license (unfortunately) does not grant you privileges to use GMRS, no, you can’t use GMRS repeaters under FRS rules. The FCC’s rules for GMRS (47 CFR, Part 95E) are our policy, in addition to the following rules:
  2. Identify transmissions appropriately.
  3. Keep language family friendly.

    Commentary: Remember; there’s kids with FRS bubble-pack radios that can easily listen in, let alone the young folks and families directly using our system – be an example, we’re not CB nor the 80 meter band.
  4. Treat any and all users of the system and spectrum respectfully.

    Commentary: Do not attack others. Leave enough room between transmissions to allow other stations to break in if needed.
  5. Limit conversations to 15 minutes in length before 7PM, then take a good long break. Alternatively, you may move your lengthy rag-chew to the sidecar.

    Commentary: There are other users who may need to use the system or are otherwise discouraged from using the radio due to “sandbagging” of the system. It is not adequate to pause the conversation and call for breaks, then resume: clear off or move to the side car, do not monopolize the system, do not hog the repeater. The repeater system is not a personal telephone service – if you need to discuss something ad nauseam you are encouraged to contact the other party via other means of communication.
    1. Exceptions: Approved nets as given in Appendix B of the Terms of Use, and emergency traffic.
  6. Do not cause intentional interference to the system itself and those using it, nor discuss acts of intentional interference.

    Commentary: If you hear it, be silent, don’t egg it on. Yes: we have malicious interference on occasion, yes: we’re aware of it, yes: we’re working on it with whatever resources we have.
  7. Do not kerchunk.

    Commentary: If you need to test your reception of the repeater and see if it’s still there throw out your call-sign to identify, such as: “[your-callsign] testing.” Listening stations are advised to not respond to ‘testing’ traffic unless asked by the station doing the testing or the call is specifically for a ‘radio check’.
  8. Disable the noise makers and beeps on your radio when using the system:
    1. Disable all roger beeps. Commentary: On Baofeng/B-Tech & Wouxun units, this means settings the “ROGER” menu to “OFF”. On Midland radios, consult your user manual.
    2. Disable the alarm button on your radio. Commentary: On Baofeng/B-Tech units, this means setting the “AL-MOD” menu to “SITE”.
    3. Do not use DTMF based PTT-ID or selective calling functions except to send intentional commands to a repeater on a radio without direct DTMF input. Commentary: not only will the repeater system mute the DTMF from being repeated (rendering it useless), you could inadvertently send a command that messes up something on the system.
    4. AFSK data bursts such as APRS, FleetSync, and MDC1200 are not permitted on the system. Commentary: AFSK based data bursts are not legal for GMRS, see: FCC Letter – APRS on GMRS and FCC Letter – MDC1200/FleetSync on GMRS
    5. Two-tone paging or other non-data types of in-band signaling for selective calling is allowed if properly identified and usage is kept to a reasonable amount.
  9. Do not use the repeaters to talk to another station on simplex unless it’s to facilitate them getting on the repeater system.

    Commentary: If you need to talk to a station you’re hearing on simplex, switch to a simplex channel or use talkaround modes. Remember that everyone else on the system can only hear one side of the conversation and you’re tying up a whole bunch of repeaters for a conversation that can be entirely sustained by simplex.
  10. Use simplex if you’re in stable ear-shot of one another.

    Commentary: There is no reason to tie up a whole bunch of repeaters between you and someone close-by. Use simplex if in simplex range of your party.
  11. Follow any special instructions or requirements when given by repeater owners, system administrators, and/or as otherwise noted on the SWCRS website.
  12. Business, commercial, or for-profit use is prohibited.
  13. Nets must be approved by the SWCRS, see “Appendix A – Permitted Radio Nets.”
  14. Remotely linked repeater systems outside of the SWCRS must comply with “Appendix B – Repeater Linking Policy.”
  15. USERS must be approved by the SWCRS to use any of its systems, see “Appendix C – Authorized Users.”

USERS are encouraged to help educate other users and enforce the above rules.

USERS shall agree to defend, indemnify, and hold harmless the OWNERS and the SWCRS and any of its affiliates from liability and claim for damages because of bodily injury, death, property damage, sickness, disease or less any expense arising from any situation resulting from the use and operation of the REPEATER SYSTEM. Use at your own risk.

Appendix A – Permitted Radio Nets

The following radio nets are permitted on the REPEATER SYSTEM. Radio nets carry no affiliation with the SWCRS, except when explicitly noted. Nets may be approved and authorized prior to implementation into this policy prior to the board acting to amend the following list with verbal or written approval from an officer of the SWCRS.

  1. Southwest GMRS Net, meeting every Sunday at 5PM MST
  2. National GMRS Net, meeting every Sunday at 6PM MST
  3. Tech Net, meeting every Wednesday at 7PM MST

Appendix B – Repeater Linking Policy

The REPEATER SYSTEM is available to external repeaters (‘NODES’) on a case-by-case basis for the purposes internet linking via Asterisk APP_RPT using the IAX voice protocol and as part of the myGMRS network.

Those wishing to link their own hardware to the SWCRS as an external node are to:

  1. Coordinate with the SWCRS admin team to establish a record for your node(s) on our network’s registration server and coordinate technical requirements. While the SWCRS is part of the myGMRS network, you will not be able to connect directly to SWCRS network elements without this in place. Contact:
  2. Connect to the main hubs only – 20400 for AZ or 23500 for NM.
  3. Your node should not be connected to any other nodes except other nodes you also own. Do not interconnect other systems to the SWCRS through your own nodes. Do not connect high-traffic repeaters. Nodes must have a receive PL or DPL enabled; CSQ is not acceptable.
  4. Please refrain from connecting systems with sub-par audio; link audio is to be flat, meaning it is de-emphasized exactly once after the receiver’s detector on either the radio receiver side or the node controller side. Audio levels should be well calibrated.
  5. All connected nodes must report statistics to the myGMRS network and must be visible on the myGMRS network map.
  6. If you schedule an automatic connection to our hubs, schedule that connection 10 minutes before a planned net.
  7. When connecting directly to our system, your users and system must follow all rules of the SWCRS. We do not impose our rules when indirectly connected through the myGMRS regional hubs (169, 172, 174, 175, 176 and 177)

Access to the REPEATER SYSTEM is a privilege, not a right. SWCRS reserves the right to disconnect or block nodes or external repeater systems that cause interference, social agitation, or otherwise generate excessive traffic. The SWCRS is not responsible for troubleshooting problems with external nodes on the myGMRS network and makes no guarantees of network availability – we’re not a linking tech support service.

Appendix C – Authorized Users

Only licensees explicitly authorized to access the REPEATER SYSTEM may utilize the REPEATER SYSTEM. The SWCRS maintains a list authorized licensees, use by unlisted personnel is not permitted. The SWCRS will readily furnish a list of users to any authorities having jurisdiction when requested to do so.
