The RMHAM Network incorporates multiple groupings of repeaters, called an “IP Site Connect” by network designers.   We have linked selective repeaters together to create local, regional and wide area coverage.   We use only the Talk Groups listed below on the RMHAM network.  Brandmeister support will be included on another page.

Microwave Network

We are currently in the process of extending our microwave link system 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. We continue to expand and operate with your generous donations, to find out more click 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

Motorola filed and received approval on applications with the FCC to add emissions designators for use in many different radio services.  With the recent filings, the modes we use f0r amateur service are classified 7K60F7W for the repeater stations, mobiles & portables are classified as 7K60F1W which are all specifically allowed in Amateur Radio Service in Part 97.  These are now perfectly acceptable for use in amateur radio service.  With the receipt of these approvals, we believe that usage is not contrary to FCC Part 97 and allowed.

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 ID packet every 10 minutes as required.  Encryption is never allowed in part 97 and must not be used on DMR.

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.
