RMHAM Adds New Salida Machine and Update Colorado Connection

09/14/2014

DSCN0624 9/14/2014 The Rocky Mountain Ham Radio team (K7PFJ, K0GUR, K0JSC and W0VG) went to Methodist Mountain in Salida, Colorado to install a new high speed ham band internet microwave link to Fremont Peak at the Royal Gorge (With the help of Matt, W1ATE and Thirza W1NDX at Fremont) to interconnect the new MotoTRBO machine and backhaul the Colorado Connection’s 147.285 Salida machine to the rest of their system.  The team installed the new 100W MTR3000 and two bay UHF antenna on the RMHAM network and a new 100W MASTR-III on the Connection.  In the process of installing the system, we determined that the old system was damaged by lightning, destroying the polyphaser lightning suppression and detuning the VHF Duplexer.  A new polyphaser was installed and the duplexer retuned giving the users of the Colorado Connection new 21st century interconnect to their system.DSCN0628

The coverage of the site is all of the Southern end of South Park and the Eastern end of the San Luis valley.  This installation opens up vast new areas previously unavailable to MotoTRBO users.  See MotoTRBO in the menu above for more information on our system.DSCN0629


Boulder Mountainbike Alliance Uses 449.225

09/12/2014

bma_logoHey Rocky Mountain Hams,

On behalf of the Boulder Mountainbike Alliance and the team of hams who provided communications for this year’s “Caribou Classic / Sufferfest” event, I’d like to thank you for graciously allowing us to use your  repeater for the event on Saturday.  While we didn’t completely devour the repeater throughout the day as we had in prior years, your repeater was absolutely crucial to the safe functioning of this event.  BMA had more riders than ever before, and better communication than ever before.   It all went eerily smoothly, in no small part due to the combination of your repeater and our bigger-than-before ham team this year.  Thank you.

We deeply appreciate your generosity all these years, and you can bet I’ll be making the same request again next year.

73,

Rocky Mtn Ham Radio Rebuild Colorado Connection COS

09/01/2014

Sunday, August 31, 2014 three different groups came together to complete the Cheyenne Mountain, Colorado Springs installation. The Colorado Connection, Colorado Repeater Association and Rocky Mountain Ham Radio installed a spur of new microwave, digital linking and new GE MASTR III repeaters. This day was the culmination of years of design an implementation to attempt to upgrade the system usability of their respective systems. As of the writing of this email, the link to Colorado Springs was very solid and the quality of the audio on the system is exceptional compared to the old analog linking systems.

The CRA also installed their digital link in Colorado Springs and will be completing the tie in to their Conifer Mountain and Lee Hill sites.

In addition to the update of these links, Rocky Mountain Ham Radio has installed a new MotoTRBO repeater on Cheyenne Mountain to bring DMR-MARC into the Colorado Springs area. For more information as to the available MotoTRBO offerings, please see MotoTRBO in the menu above.

RMHAM Installs MotoTRBO on Sandia Crest, NM!

08/25/2014

DSC_5779Albuquerque, NM has a MotoTRBO repeater!  The RMHAM install team made an ascent to the top of 10,600′ Sandia Crest to install and connect the Motorola MTR3000 repeater to Colorado Wide and South talkgroups.  From left to right: Scott Webb N5SQR, Brian Mileshosky N5ZGT, Tom Ellis K5TEE, Chris Aas NB5T, Pat Mileshosky W5RMY, Isaac Trujillo W5IDT, Ed James KA8JMW.

They brought it up Saturday, August 23rd, and tested the system for coverage blanketing the whole Albuquerque Metropolitan area.  The system is connected to the Colorado Wide and Southern Colorado talkgroups temporarily while testing.  They will be moved onto their own talkgroups after they decide what content they’d like to carry.

You might hear them on the network, so make them feel welcome and congratulate them on a job well done!

The frequencies will be added to the RMHAM standard codeplug when the talkgroups have been decided.

 


CSVHF 2015 Conference comes to Colorado

08/13/2014

Hi all

The Central States VHF Society is pleased to announce that its Annual Conference for 2015 will be held in the Denver Colorado Metro area. We are currently working to deliver an exceptional lineup of technical programs with presenters from across the country. Technical proceedings will be published and made available at the conference. Anyone wishing to submit a paper, or propose a technical session topic, should contact the Conference Vice President John Maxwell, W0VG. johnm@johnmaxwell.net

As with all conferences, we will also offer the traditional social activities; noise figure measurement, antenna range, Rover vehicle show and tell, luncheons and a banquet.

The local host for 2015 will be Rocky Mountain Ham Radio. The organizing team is working to bring a “Colorado Flare” to the event. We are considering a number of social activities that build relationships between Colorado locals and visiting CSVHFS members. Operating events from local mountain top locations are being considered. Stay tuned.

We will continue to offer the VHF101 program for those looking to get started with VHF and UHF weak signal operation. These sessions will be promoted locally and designed to encourage newer hams to get involved in weak signal operation on the VHF+ bands.

At this time planning is underway for a suitable venue with all the amenities that CSVHF conference attendees are accustomed to enjoying. Firm dates and facility location will be announced as soon as they are secured.

Anyone desiring additional information may contact Doug Sharp, K2AD ( doug@dougsharp.com ) or Wayne Heinen, N0POH ( n0poh@wayneheinen.com )

We hope to see you in Denver in 2015!

73,

3GHz Microwave from Fort Collins to Pueblo Complete!

07/28/2014

20140719_080149Friday July 17th saw a merry band of RM Ham members making the long trek to the base of Almagre Mountain and the next day make the one hour trip up the service road to the site. The site is close to 13,000 feet and it was certainly a labor of love for those hardy souls to work at that altitude! Physical installation of the new 3 GHz microwave equipment was made as well as some general maintenance and cleanup at the site. The crew included (in no particular order) K7PFJ, K2AD, KØGUR, WØVG, KØPWO, KØRM, WA2YZT, WØKVA, KØJSC and K1DDN, who watched over the base camp.
Sunday July 27th saw WØVG heading for Devil’s Head and KØJSC and ACØKQ heading back to Almagre Mountain for the final tweaks to the 3 GHz links and final tweaks on the UHF TRBO and the new Mixed Mode VHF. The 3 GHz all amateur band backbone now stretches from Pueblo to Fort Collins. The final 35 mile link was running a -47dBm. Next stop Raton Pass!

Rocky Mountain Ham 2014 VHF Contest

06/28/2014
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
117126

 

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!
