RMHAM-New Mexico is pleased to announce the 2015 New Mexico TechFest, an ARRL-sanctioned operating specialty event, on Saturday February 28, 2015 at the New Mexico Veterans’ Memorial Event Center located at 1100 Louisiana Blvd SE, Albuquerque, NM 87108.
Join fellow amateur radio operators from around the Land of Enchantment for a day of quality presentations, demonstrations, and instruction provided by some of New Mexico’s leading technical hams on a variety of emerging and relevant technical topics within amateur radio today. The New Mexico TechFest is designed to provide a unique opportunity for all hams interested in the technical aspects of our hobby to advance and expand their technical knowledge and to facilitate technical discussion, collaboration, and ideas with one another. Ham-specific and presentation-related prizes will be drawn throughout the TechFest event. Refreshments including coffee, water, and light snacks will be available. Tables will be provided for attendees to set up and conduct informal ham-related technology and project demonstrations between presentations, during lunch, and at the conclusion of the event.
For complete details or to register online, please visit the New Mexico TechFest event page.
Saturday, RMHAM tested one of it’s member’s, Zeke Ragsdale’s son. Colton Ragsdale, 5 years old, passed the test missing only three questions! He had the test read to him by RMHAM Members, Dean Mertz, K0MKT, Ken Zylla, KD0MGQ and George Bartling, WA9TCD. Congratulations, Colton!
In an expansion of the cooperative agreement between the Rocky Mountain Ham Radio and the Aurora Repeater Association, the 447.500 repeater, which lost it’s Conifer Mountain site back in August, is now located at Critchell, in place of the 447.225 analog pair. At 8,400 feet it is not quite as high as the old Conifer Mountain site but it does enjoy coverage of the southern portion of the metro area. The repeater was placed on Critchell Monday December 29 by Steve KØIBM and Scott NØOWY. There was a flurry of activity as people who had been regular users of the 447.500 machine found it lighting up their rigs in the scan mode. As we go forward, we’ll learn more about the coverage that the machine will enjoy using the ARA’s configuration. Rocky Mountain Ham Radio has relinquished their 447.225 pair back to the Colorado Council of Amateur Radio Club’s frequency pool at this time and is preparing to re-purpose the equipment that was at the site. The parameters of the 447.500 (-) repeater remain the same with a 88.5 Hz CTCSS tone.

Those who signed up for the AllStar Linking class got both an introductory and in-depth look at the All Star repeater linking technology including the required hardware and software. The “students” where treated to lively anecdotes and a dose of real word applications of this versatile system. RM Ham University classes cover a variety of subjects click on the RM Ham University tab and see what’s available!
Our Instructors were John W0VG, Jeff K0JSC and Doug K2AD
Rocky Mountain Ham Radio Inc. and the Aurora Repeater Association have signed a Cooperative agreement that will allow the Boards of Directors of both groups to interact and work together to better use both groups resources in a cooperative effort to further technological advances in Colorado. The first project for the Cooperative will be to split the responsibility for the “Multimode” Narrow Band FM/TRBO VHF repeater that nominally operates with an output frequency of 145.175MHz. The Cooperative agreement between the two organizations will be the cornerstone for more increased resource sharing and project planning for the betterment of amateur radio in Colorado and a sign of things to come!
If you’re new to MotoTRBO or just wanting to learn more about how it all works, you’ll be sure to mark your calendar for the First and Third Saturday of every month. Come to Colorado Wide and participate in the new MotoTRBO tech net.
We’ll have system designers and tech geeks there to answer your questions and help you to understand how to get the most out of your DMR radio. The net will be held on December 6th at 7PM on Colorado Wide, Talkgroup 700.

See you there,

October 25th was a gorgeous Saturday and for the Rocky Mountain Ham Radio crews a perfect day to tackle some of the last of the mountain repeater site chores. At Squaw Mountain Dave Maciorowski WA1JHK, Doug Sharp K2AD and Willem Schreuder ACØKQ reworked the microwave link from there to Devilshead and buttoned up some final last minute fixes.
At Devilshead the other end of the Squaw Mountain link was reworked and a new link to Badger Mountain established. They added a second frequency link radio and cable to the Almagre path as well. Scott Taylor WØKVA, Scott Burkhardt WØKU and Dean Mertz KØMKT took care of these tasks.
Badger Mountain is located south and west of Colorado Springs off of US Highway 24 near Hartsell.

Going to Badger Mountain were Mike Mullarkey K7PFJ, John Maxwell WØVG, Mike Gurski KØGUR, Wayne Heinen NØPOH and George Bartling WA9TCD There was lots of work to do here. There were two two foot dishes which required assembly, installation on the tower and alignment on the appropriate link paths. One was for the link to Devilshead and the other for a future redundant link to Cripple Creek. A two bay UHF repeater antenna was mounted on the tower and the new Badger Mountain MotoTRBO repeater and associated accessories were installed in the building.

During the 2014 year, Rocky Mountain Ham Radio personnel have spent significant amounts of time building and extending microwave radios to various locations along the front range to extend the reach of it’s radio systems. Our goal was to create a cooperative microwave network to carry IP traffic to repeater site locations while remaining technology agnostic. “We’re really creating a highway to carry all sorts of radio traffic,” said Doug Sharp, K2AD, Chief Technology Officer of Rocky Mountain Ham Radio.
Currently we have 18 hops of microwave installed into the system, adding more as time an weather allows. Plans are in the works for at least 6 more hops of radio and a few more MotoTRBO repeaters to extend the Colorado network.
While we would love to continue building these systems, maintenance of these systems are extremely time consuming. Distance from end to end on the microwave system is about 5 hours. We need to have partners to assist us in extending the reach of the network. Jeff Carrier, K0JSC signed on to do the Pueblo County/Fremont County extension and bring us closer to our goal of interconnecting with Rocky Mountain Ham Radio, New Mexico’s network currently under construction.
We have partnered with K0JSC for Pueblo/Fremont, N5UBJ, Bill VanHuss for Durango/LaPlata, W0FT/HEAHR for Ft Morgan. This can’t be done without help and support from all of these people and we welcome inquiries for network extension assistance!
