Rocky Mountain Ham 2014 VHF Contest

Pueblo, Where Old Rovers Go To Die.

Pueblo, Where Old Rovers Go To Die.

The ARRL 2014 VHF QSO Party was operated on June 16th and 17th from DM78 Southeast of Pueblo. The Rocky Mountain Ham Radio team again fielded a great station with 9 bands. The team put in a great effort and submited the following score

We did have gear for 2304 and 3456 but true to form, there was nobody to talk to on those bands.


Band QSOs Grids
50 MHz 629 128
144 MHz 41 15
222 MHz 8 7
432 MHz 12 8
902 MHz 1 1
1296 MHz 2 2
10 GHz 1 1
TOTAL 694 162


All in all, the band conditions were bad this year compared to the last 5 years,  but we did have some openings that allowed us to work quite a few stations.  Local noise at the site was a bit high, but strangely enough kept moving around physically and could not be pinpointed to one location!   We will have to work on this later this year and see how we do for 2015.  Pray to the gods of propagation for 2015!



RMHAM Assists Colorado Coal Century


logoMay 17, 2014 Rocky Mountain Ham Radio assisted the organizers of the in pulling off a great early season 100 mile bike ride starting and ending in Broomfield, CO and traveling along many country roads to Johnstown, CO.  Many RMHAM members gave their Saturday in hopes of creating a wonderful ongoing, early season bike ride for the front range.

We provided health and safety communications as well as tracking first and last riders as well as providing sag services and access to emergency medical.  We deployed and used 8 APRS trackers on our Lee Hill digipeater, the communications trailer and about 20 of our club members to successfully execute a great event.

The Broomfield Rotary Club was the main organizing committee for the event and was very amazed by the tools and technology that we’re capable of.  A sincere appreciation was expressed for all of the members of the Rocky Mountain Ham Radio team that deployed to assist in this adventure!

Thank you for your time and dedication!

RM Ham Trailer Cover Story!


5-1-2014 5-55-10 PMBack in December, 2008 I had an article published in the pages of the now closed Monitoring Times Magazine “A Trailer for All Seasons,” about RMHam’s original Communications trailer, dubbed CommTrailer 2006, in this latest article “Rocky Mountain Ham Radio Communications Trailer”. The Spectrum Monitor is an e-magazine in pdf format that was created by Ken Reitz KS4ZR former editor of Monitoring Times. Many of the columnists and former contributing authors to Monitoring Times are a part of it now, and I count myself fortunate enough to join them.
As we know this, our second generation trailer, has many innovations that arose from the “what ifs” that we asked ourselves over the years, “if we ever build another trailer” I approached Ken with the concept of this article and I’m pleased that it became the cover story for this month’s issue, which is dedicated to Amateur Radio.
We at Rocky Mountain Ham Radio invite you to check out The Spectrum Monitor, a full service monitoring journal covering DC- to Daylight, Amateur, Public Safety, Utility and Broadcast monitoring.
Feel free to download the article, including errata pages, in pdf Rocky Mountain Ham Radio Communications Trailer and visit The Spectrum Monitor to see what they’re all about. 73 Wayne


Analog Repeater Controller Class



Rocky Mountain Ham Radio sponsored comprehensive courses in the basics of analog repeater controllers to 21 hams from Colorado. The class was presented on February 22, 2014 by Mr. Dave Maciorowski, WA1JHK, who is a repeater controller expert from SCOM in Loveland, CO. Mr. Maciorowski has been designing, building, maintaining and writing software for repeater controllers since the 1970′s.

The syllabus for the class included:

Analog Repeater Controllers 101
General Overview
- Audio Ports
- Signalling Ports
- Logic Inputs
- Logic Outputs

Analog Repeater Controllers 102
Hardware Interface
- Interfacing to audio interfaces (TX, RX, decode CTCSS, encode CTCSS)
- Interfacing to signalling interfaces (COS, PTT)
- Interfacing to logic inputs and outputs

Analog Repeater Controllers 103
Software functions
- Basic programming (callsign, passwords, timers, access mode, etc …)
- Advanced programming (macros, triggers, A/D converters, etc …)

Analog Repeater Control Applications 201
Adding links; radio or digital audio interfaces
- Interfacing link equipment to a controller
- Special considerations (filtering CTCSS, passing IDs, multiple hang tails, etc …)
- Macros to support remote enable and disable of links.

Don’t forget that we offer Rocky Mountain Ham University on a regular basis and you’re welcome to attend.  See the menu above.

RMHAM Test Bench


2014-02-23 15.40.29Did you ever wonder how we make all of the network hardware work? Well, we build a test bench with whatever hardware is required to duplicate the network and load them up exactly the way they would be in the field.  We use the same networking gear and configurations so that we can prove out all permutations and make the equipment work exactly the way it should in the field.

Some of the field locations are 12 hours round trip without any time on site, so having a good, solid plan with working equipment is critical.  The picture above is Mike Mullarkey, K7PFJ with our test bench for deployment of new repeaters, routers and fiber connections for Lee Hill and Almagre Mountain.


RMHR Receives Award from Boulder County ARES!


1622132_10200892388226746_296146765_nRocky Mountain Ham Radio received an award last evening from Boulder County ARES for the response and equipment provided in support of the Boulder floods. Jeff Ryan was in attendance and said “I was honored to accept on behalf of this fine organization.”

“The Hamfest” a Huge Success!


Sunday, February 9, 2014.  Aurora Repeater Association, Cherry Creek Young Amateur Radio Club and Rocky Mountain Ham Radio held their annual hamfest at Adams County Fairgrounds.  The turnout was spectacular on a gloomy, yet cold morning.  We beat our attendance figures by nearly 25% over last year.  There were many visitors in attendance, from League dignitary Brian Mileshosky from Albuquerque, NM and many other folks from around the state that braved the early morning road conditions and fog to make it to the event.  A special thanks goes out to all ARA, CCYARC and RMHAM folks that made this event a simple and memorable event!

Looking forward to seeing you all next year.

Analog Repeater Basics


Rocky Mountain Ham University hosted a class on Analog Repeater Basics on January 11, 2014. Mr. Doug Sharp, K2AD, from Rocky Mountain Ham Radio gave an excellent presentation to 25 enthusiastic attendees. During the 4-hour class, Doug explained in some detail the fundamentals of analog repeaters, hardware for analog repeaters, and the systems incorporated into analog repeaters.

Doug also took the opportunity to explain the fundamentals of Rocky Mountain Ham Radio to the class. A number of attendees had little understanding about the tremendous service that RMHR provides to the ham-radio community, to the public, and to ARES. Doug therefore briefly explained this purpose of RMHR, and the new technology and sophisticated systems provided and maintained by RMHR. There was also emphasis on the fun that RMHR members have while serving. Doug welcomed all to explore becoming a member of RMHR (no dues required), or of its affiliated ham-radio groups so that the services can grow and continue.

Following the class, many of the attendees gathered for a Mexican-food lunch to do what hams do best: chat and enjoy other hams! See photos of the class here.
