The Swapfest 2018

03/03/2018

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

02/08/2018

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

12/16/2017

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.


AT-D868UV Questions and Silver Lining

AT-D868UV in VHF digital simplexAT-D868UV in UHF digital simplex
These are VHF and UHF (respectively) captures from the AT-D868UV dual band DMR handheld.

This indicates timeslot violations during the first ~100ms of a DMR transmission, which quickly settles down to normal behavior. Other than this timeslot violation the RF is clean, looking about as good as offerings from Connect Systems and Tytera. Read more →

Directly from their website:

Maker Faire is the Greatest Show (and Tell) on Earth – a family-friendly showcase of invention, creativity and resourcefulness, and a celebration of the Maker Movement. It’s a place where people show what they are making, and share what they are learning. Makers range from tech enthusiasts to crafters to homesteaders to scientists to garage tinkerers. They are of all ages and backgrounds. The aim of Maker Faire is to entertain, inform, connect and grow this community.

The original Make Faire event was held in San Mateo, CA, and in 2014 celebrated its eleventh annual show with some 1100 makers and 130,000 people in attendance. World Maker Faire New York, the other flagship event, has grown in four years to 600+ makers and 80,000  attendees. Kansas City, Detroit, Atlanta, Milwaukee, Orlando, Silver Spring, Paris, Rome, Oslo,Trondheim, Tokyo, Newcastle (UK), and Shenzhen – and now DENVER – are the home of larger-scale “featured” Maker Faires and over 120-community-driven, independently organized Mini Maker Faires are now being produced around the United States and the world.
