ARRG supports the Annual Cystic Fibrosis Cycle for Life Ride

July 16, 2016

2016 Cycle for Life Ride     Marc Douglas, AE7KK Net Control

Left: Radio Safety Team being led by Marc Peterson, W7PM and Joe Boyd, the CF Director     Right: Marc Douglas, AE7KK operating Net Control

 For the third year in a row, dozens of ARRG members and other area Amateur Radio volunteers came together to as the CFL Radio Safety Team.

Our team not only provided 14 volunteers, we also brought along all the radio equipment needed to set up a two Net Control radio positions, the NC operators, Rest Stop operators and four SAG (Support and Gear) operators and their vehicles.


Net Control was setup at the start/finish line which was located at the Oak Knoll Winery in Hillsboro. Special thanks to Pat Roberson, W7PAT, Jenny Roberson, KA7JNY, Marc Douglas, AE7KK and of course Lynn Burrell, KE7WKM for setting up all the radios, antennas and portable phone system in Lynn’s beautiful motor home he provided for the entire event.


OMSI Maker's Faire Amateur Radio Educational Event

  The event will be on Saturday 09/10/16 and Sunday 09/11/2016 and operate from 10AM to 5 PM daily


Display and Table Help Needed

ARRG is once again leading the Amateur Radio presence for the 2016 OMSI Mini Maker's Faire. We have a great air conditioned space that we need to fill with interactive displays that will teach and educate the public about Amateur Radio.


We are currently seeking other groups or individuals who would like to build a interactive Amateur Radio display covering your favorite Ham Radio topic.

We still have several open 8' tables (displays) available. ARRG will be setting up two HF and VHF/UHF radio positions in hopes of getting people on the air.


Other topics we’d like to see covered in the space are Emergency Preparedness, Info about ARES and CERT, info about Ham Radio and how to get licensed, technical topics like APRS, MESH or Digi formats or any topic that uses Ham Radio that you think would be exciting and educational. Groups or Individuals will not have to pay for booth space when coming into the ARRG space. Please contact Marc Peterson, W7PM at if you are interested in helping design and setup a table display.


As an Oregon Non Profit 501C (3) public service organization, the Amateur Radio Relay Group provides wide area repeater systems which provides both emergency communications training and traffic handling and for normal  day to day uses by the Amateur Radio community. ARRG owns and operates the 16 repeaters which make up the entire K7RPT repeater system. Our repeaters are strategically positioned around Oregon State, with more being designed and put together for future expansion and for the overall good of the Amateur Radio community.


Our communications system is currently used by State and Local Emergency Service teams, Amateur Radio Emergency Service teams, Community Emergency Response teams, Search & Rescue and by dozens of other service organizations.


When not used for Public Service events or Nets, the K7RPT repeater system is made available for use by any properly FCC licensed Amateur Radio Operator.


Over the years, the K7RPT system has been used as an important 'lifeline' during times of accident, injury and disaster when local landline, Cellular or Police/Fire communications have failed. The K7RPT repeater facilities are often located within existing Public Safety facilities and all have emergency power backup via generator and battery backup. With an emphasis on emergency preparedness, our repeater facilities are built to withstand most manmade and natural disaster scenarios. 


We still need your help!

The repeater group that was to become ARRG started back in 1972 with its very first repeater on South Saddle Mountain and later became officially incorporated as ARRG by the State of Oregon in October 1977.

ARRG is one of Oregon's original Amateur Radio groups and is still one of the larger Amateur Radio teams that are active.

The YSF (System Fusion Page was just updated. We've added 50 new YSF repeaters into the repeater guide. Please check it out here

July 1, 2016
The Astoria Wickiup 444.125 + 100 Hz test repeater was installed.
The repeater has a fulltime link into the South Saddle System.
The site was found to have terrible site noise, so this probably won't be a permanent home for the 444.125.

April 19-25, 2016
The 444.125 Chehalem Ridge site is being upgraded with a new antenna and 30' tower.The frequency will be changing from 444.125 to
444.400 + 100Hz sometime April 25th.

In our goal to offer the nightly ARES District One Net better coverage into the five counties that the D1 serves, the ARRG technical team is testing a new linking system that will connect both the South Saddle system and the Sylvan Repeater System on a daily basis.

The D1 net, which is currently carried on the South Saddle System via the 147.320 and 442.325 repeaters is now being carried nightly on the Sylvan Hill Repeater on the KOIN Tower @ 147.040 + 100.0 hz

The new controller we installed and programmed will auto connect and then later auto disconnect the two sites per the following schedule

Regular District 1 Net
Mon, Tues, Thurs, Fri and Sat
Repeaters will automatically link together at 07:15 PM and the link will automatically drop at 8:15 PM

Wednesday 07:15 PM to 9:00 PM
For the D1 and SKYWARN nets: repeaters will automatically link together at 07:15 PM and will stay linked up through the SKYWARN net until about 9:00 PM.

Sunday 07:15 - 10:00 PM

The D1 will be linked up and the system will remain linked throughout the 8PM Neighborhood Emergency Net
