RMRL MEMBERSHIP INFORMATION
Dear Prospective Member,
Thank you for your interest in the Rocky Mountain Radio League (RMRL).
The RMRL is a Denver-based 501(c)(3) non-profit amateur radio club that emphasizes VHF and UHF repeater operation. We are affiliated with the American Radio Relay League. Members are located up and down the Front Range from Cheyenne to Colorado Springs. Membership fluctuates around 250. Activities include furnishing communications coverage for civic events, emergencies, and a severe storm-warning network to assisting the National Weather Service. Social events include a holiday dinner each year.
The club owns and operates three 2 meter repeaters (145.220, 145.340, and 146.940 MHz), one 1.25 meter repeater (224.000 MHz), and four 70 cm repeaters (449.125, 449.450, 449.750, and 449.825 MHz) which serve the Colorado Front Range. All of the repeaters except 449.825 are located at mountaintop sites near Golden, Idaho Springs, and Evergreen. Elevation at the sites ranges from 8,300 to 11,440 feet. The 449.825 MHz machine is located near Broomfield at approximately 5,600 feet.
- 145.220 provides excellent HT (handheld radio) coverage throughout the metro area.
- 145.220 and 224.000 have an autopatch available to members.
- 145.340 is Node 3350 on the Internet Radio Linking Project (IRLP) network, and may be linked to other repeaters around the world using voice-over-IP technology on the Internet.
- 146.940 and 449.450 are wide area coverage machines reaching Cheyenne to the north, Colorado Springs and Pueblo to the south, a wide area of the eastern plains, and west to the Continental Divide.
- 449.750 provides excellent HT (handheld radio) coverage throughout the metro area.
- 449.825 is linked full time to the 146.940 repeater, extending its coverage into Boulder and other “shadowed” areas.
- The 449.450 and 449.750 repeaters are part of the SkyHub Link System, an all-mode link system providing a communication bridge between many amateur radio repeaters and networks.
We also have a balloon-flyable repeater with a receive frequency of 445.975 MHz and a transmit frequency of 147.555 MHz. This repeater is flown periodically by the EOSS balloon launch group.
ALL RMRL repeaters require a 103.5 Hz CTCSS tone for access. The repeaters also transmit either a 103.5 Hz or a 127.3 Hz CTCSS tone. If your receiver has CTCSS decode, you can utilize this feature to reduce intermod and noise between repeater transmissions.
The RMRL uses all commercial equipment (GE MASTR II repeaters and S-COM controllers). New state-of-the-art equipment is added from time to time. Down time on any one unit is short due to excellent technical support. Control operators monitor the frequencies to provide orderly and authorized use of the equipment and frequencies.
We have an on the air meeting each Monday evening at 8:30 PM local time on the 146.940, 449.450, and 449.825 repeaters. The club keeps its members up to date with regular postings of events and information in the QRZ section of the website. A roster listing the call letters, address and phone number of each member is distributed annually.
A family membership is $20.00 annually and covers all amateurs in your household, including students away from home who claim the parents’ address. There is also a youth individual membership for $5.00 per year, which is available to amateurs 15 years old and younger whose parents are not RMRL members. The RMRL is a 501(c)(3) non-profit organization and contributions are tax deductible.
On behalf of the membership of the RMRL, I invite you to join our group. We would welcome your participation in and support of our activities.
