    The following area systems will be in use by amateurs providing communications in support of the Allianz Partners Richmond Marathon all morning and most of the afternoon on Saturday, November 16:

    • W4RAT 442.550 MHz repeater (FM)
    • W4RAT 146.880 MHz repeater (FM)
    • KG4MRA 145.430 MHz repeater (FM)
    • DMR Richmond Metro talkgroup

    While these area repeaters are in use, please consider the following alternatives:

    • KA4CBB 147.36 (input PL 127.3) in Chester
    • KA4CBB 442.15 (input PL 162.2) in Chester
    • WA4FC 147.39 (PL 74.4) in Petersburg
    • N8ELS 145.11 (PL 74.4) in Hanover

    C4FM/WIRES-X users:

    • WIRES-X services will be disabled on 146.88 during the marathon, and the repeater will be configured to repeat C4FM traffic in FM mode (as the 442.55 already does).

    DMR users:

    • Please keep clear of TS1 talkgroups on the RATS 443.5875 repeater (DMRVA "RIC" zone) during this event.  This includes Richmond Metro, TAC A & B, the Virginia regional talkgroups, and "private" radio-to-radio calls.  Virginia Statewide and HEARS on TS2 may be used as normal without interference to marathon operations.

    • Please keep clear of RVA Metro (27500/31511) on all repeaters and hotspots.

    • If you wish to utilize one of the TAC channels or regional talkgroups, please use one of these other DMRVA network repeaters serving our area:  Beaverdam (BEA), Goochland (GCH), New Kent (NKC), or Powhatan (POW).  Note that you will be be competing against TS1 activity on Richmond Metro;  VA Statewide is recommended.

    Event radio traffic can be monitored online at the links below:

    Amateur radio support for this event is being coordinated by the RATS Public Service Committee.  For information contact Jim Rubin W4PKR.

    Dues for the 2024-2025 RATS membership year are due by September 30.  Members who do not renew by EOD 9/30 will transition to a lapsed status on 10/1.  Lapsed members lose their voice in club affairs and no longer count as a voting member for quorum purposes.  Members have until December 30 to reinstate their lapsed membership by payment of past-due dues.  After that date, a new membership application and vote-in will be required.

    The RATS Codeplug Project is considering support for select Motorola radios.

    We're starting with an experimental codeplug for the XPR7550.  This is a LTD codeplug that follows the usual RATS channel layout in the Richmond, Beaverdam, Goochland, New Kent, Petersburg, and Powhatan repeaters, and the two local portable repeaters.  [Note:  At this time, the 3-character channel label prefix (RIC, BEA, etc) is not implemented in this test codeplug.]  This file is based on a seed codeplug obtained from the SCHEART DMR network and it requires Motorola CPS 2.0.

    Experimental codeplugs for the XPR2500 and XPR7550e have also been posted.  If these become permanent, this will bring our list of officially supported radios up to 51 models (plus 10 more with unconfirmed support).

    The Motorola CPS is now available free of charge to ham radio operators, direct from Motorola, for their personal, non-commercial use.  While both the new CPS 2.0 product and the legacy CPS 16 are included in this offer, should we decide to move forward with additional support for Motorola radios we'll be focusing on development efforts in the CPS 2.0 system, which is not backwards compatible with CPS 16.

    Motorola equipment owners in the Richmond metro area who would like to see support for their specific model should contact codeplug-request@rats.net for consideration.
