DMR Information for Hamvention 2014


           UPDATES  (check back frequently)

  Attendance results are in and also all counts from 1991-2014
Hamvention will stream Live streaming Video or see video at bottom of page
All Codeplugs are coded, no further updates unless mistakes are found.  Did add Ohio St to timeslot 2 for the MARC repeaters and timeslot 1 for DCI.
DCI's primary contact points will be: 1) Fleamarket repeater (or talkaround if repeater is off-air, 2)  Simplex 4 (433.75000, TS1, TG 99) and 3) Dayton North repeater on Ohio (TG 3139 on TS2).  So be sure to program Ohio State (3139) as it is carried by both MARC (on TS2)and DCI (on TS1) and will be primarily for Hamvention wide area use.  Hara 4 Simplex (433.45 TG 99 on TS 1) for on-site simplex also.
DCI Michigan repeater will be onsite Saturday 0800-1700th at a minimum.  Or use Hara 4 Simplex to find us.  Check back for additional times at Hara.  Also will be at Hotel Alley Friday evenings & Saturday & Sunday mornings.

Introduction to DMR  John Burningham, W2XAB; moderator & author
Friday, 1545-1700, Rm 5, Get your "DMR for Dummies" book, will be SRO

DMR is an international standard for professional digital two-way radio systems.  A number of manufacturers including Motorola Solutions (MototrboTM), Hytera, Harris, BFDX, Tait, Vertex Standard, Connect Systems, Rayfield Communications, and Kenwood are involved with DMR. This presentation will include a basic introduction to DMR Tier2 which has been implemented in a number of Amateur Radio networks worldwide including the DMR-MARC and DCI networks. There are currently over amateur 550 repeaters and over 6000 users worldwide.

Time is running out.  We still need help with local Dayton repeater frequencies and info useful to (DMR) attendees.  If you know any info, especially HT coverages for Hara outside and inside as well as Hotel Alley (Miller Lane just south and east of I-70 and I-75 about 7 miles north of the center of the city of Dayton), please pass it along via Email to DCI.
