DMR Site Information

Rocky Mountain Ham Radio’s DMR Network Information as of 10/19/2020

SPECIAL NOTE:  Private calling, texting, DPRS/APRS/GPS Location Services should never be used on the RMHAM network.  Only our Brandmeister  repeaters on talkgroups specifically allocated for APRS/DPRS/GPS activity should be used for this. Please note that autonomous (GPS/Text or data) transmissions must be identified with your FCC callsign.  An ID number isn’t a legal identification.
Sample Codeplugs for several radios are available in the menu above under DMR Network.

Microwave Network

Rocky Mountain Ham Radio has built and operates a microwave network covering three states.  Our microwave link system covers throughout the Front Range from Wyoming to the Albuquerque and West to Vail to interconnect our radio sites on Amateur Radio frequencies and not be reliant on the commercial Internet as much as possible.  We’ve linked of our front range sites and are working to add others as quickly as the funds and time will allow. Rocky Mountain Ham Radio is an IRS 501(c)(3) Charitable Organization. Any donations you may care to make are fully tax deductible. Learn More Here

If you have access to a radio site and internet access and would be willing to assist us in creating and managing this network, please contact us and discuss what we can do to make this happen. We would like to create the network around the state, but we’re not building overlapping coverage.  If you have a site, and it makes sense for us to deploy there, we will see what we can do!

DMR Legality on the Ham Bands

The FCC has allowed DMR on the amateur bands by allowing the emission type specified for DMR. 7K60FXE is now allowed in Part 97.

Please note:  Certain autonomous features (like GPS positions and data transmissions) are definitely not allowed since there’s no way to transmit a FCC Legal Identification every 10 minutes as required.  Encryption is never allowed in part 97 and must not be used on DMR or any other mode.

Excerpt from §97.119 Station identification:

(a) Each amateur station, except a space station or telecommand station, must transmit its assigned call sign on its transmitting channel at the end of each communication, and at least every 10 minutes during a communication, for the purpose of clearly making the source of the transmissions from the station known to those receiving the transmissions. No station may transmit unidentified communications or signals, or transmit as the station call sign, any call sign not authorized to the station.

FCC GRANTS WAIVER:  March 22, 2013 the FCC Granted the ARRL’s  petition for a waiver to the commissions rules regarding the use of single slot TDMA on the ham bands pending permanent rulemaking proceedings on the subject.  The full order is here for your perusal.
