RMHAM University 2018-2019


We are excited to announce yet another exciting set of classes for the 2018-2019 season. RMHAM University is held on the third Saturday of every month and takes the form of a four hour in-depth exploration of a topic.

  • Oct 20, 2018: DMR Systems and Uses (Mike K0NGA)
    DMR use continues to expand and provide new interconnection possibilities.  This is an updated talk that explores how DMR works and the bewildering world of programming DMR radios to work with the various interconnecting systems.
  • Nov 17, 2018:  Ad Hoc IP Networks (John W0VG, Chris AE5IT & Willem AC0KQ)
    Providing IP in challenging terrain is one of the abilities served agencies value most because IP enables so many other services such as data, audio and video.  This talk explores planning, configuring and deployment of such a network using point-to-point microwave links, satellite and cell links, mesh networking, UHF data radios and similar technologies in mountainous terrain and remote locations.
  • Dec 15, 2018:  Test and Measurement (Bob Witte K0NR)
    How to measure noise, SWR, loss, signal-to-noise and similar things that we care about in the radio world on a ham radio budget.  How do you interpret the results and improve your station.
  • Jan 26, 2018:  Repeaters 102 (Doug K2AD)
    This class is updates the Repeaters 101 class and covers topics such as how to determine of your DMR repeater is operating properly, interfacing repeaters with linking devices such as an RTCM or MMDVM, how to determine if your repeater is de-sensing and similar topics.
  • Mar 16, 2019:  Designing, Building and Deploying your PodCom (David K0PWO)
    This class covers designing building and using a portable PodCom.
  • Apr 20, 2019:  Linking Repeaters (Jeff K0JSC & Willem AC0KQ)
    Linking repeaters together dramatically expands communications capabilities.  This talk covers linking analog repeaters using VOIP technology such as AllStarLink, digital repeaters such as DMR and P25 using native protocols and mixed technologies like MMDVM, as well as bridging between different technologies.

The classes are free and walk-ins are allowed, but we ask that you RSVP so that we can have enough coffee and treats on hand.

Classes are held Saturday mornings from 8am to about noon at

Cherry Creek Schools Educational Service Center

We usually meet for breakfast at the Village Inn at 9050 E Hampden Ave (Hampden and Yosemite) at 7am before class, and often enjoy lunch together at a restaurant in the vicinity after class to talk about the topic of the day as well as life, the universe and everything.  Please join us for some delightful conversation.

The Swapfest 2018


February 18, 2018, the weather was perfect for the first Metro area ham fest of the season. The Swapfest 2018 was a great event! We set an attendance record with well over 500 in attendance and once again sold out all the tables in the hall.
This year’s Swapfest featured the Rocky Mountain Ham University Homebrew and Kit Building Expo that had a very good turnout with a variety of presentations and great Q and A sessions.
The Aurora Repeater Association, Cherry Creek Young Amateur Radio Club and Rocky Mountain Ham Radio want to extend a hearty THANK YOU to all who participated and attended the event!

Thorodin Wind Damage


As of about 2PM on Feb 7, 2018, the Thorodin DMR went off-air as well as 449.225 analog and the Colorado Connection Denver transmitter.  The main antenna for UHF transmitter combiner broke it’s mounts at the roofline and ripped out it’s feedlines.  The system is temporarily repaired and back online as of Feb 9, 2018.  It’s amazing the damage that wind can do!  It was blowing about 25mph continuous and gusts to 60 while W0VG and Ben Hammond from Mountain Broadband were there affecting repairs.

RMHam U – Antennas, feedlines, SWR


About 25 hams attended Chris Hamilton’s (AE5IT) RMHam U class on Antennas, Feedlines and SWR (subtitled:  Every Antenna is a Multiband Antenna).   The Chris explained why even mismatched antennas can be effective radiators as long as your are using a feed line with low loss.  The class also had a practical demonstration of wave  propagation.  RMHam holds these classes monthly during the ‘cold’ months and you can sign up by clicking on “RMHam University” in the menu bar of this web site.
