Who We Are

As an Oregon Non Profit 501C (3) public service organization, the Amateur Radio Relay Group provides wide area communications repeater system for the purpose of Emergency Communications and for day to day uses by the Amateur Radio community.

The 16 repeaters ARRG operates make up the entire K7RPT Repeater System, with several more repeaters are being designed and built - all for the overall good of the K7RPT system.

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.

With an emphasis on emergency preparedness, the K7RPT repeater facilities are built to withstand most Manmade and Natural Disasters. 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 co located with Public Safety facilities and have emergency power backup via both Generator and battery backup.

Welcome to ARRG and the K7RPT Repeater System


This is the official site of the Amateur Radio Relay Group, Inc, otherwise known as ARRG.

 ARRG owns and operates the 17 repeaters that make up the K7RPT repeater system.


We are a technical communication team and our primary purpose is to build, install and maintain modern repeater communication systems for use by Amateur Radio Community.


ARRG also freely provides our repeater systems for the use of emergency / disaster communications teams which include State, County and City Agencies, as well as the ARES D1 group, Beaverton CERT, Search & Rescue Teams and many other public service organizations in and Oregon State and the surrounding area.


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.

ARRG has been a American Radio Relay League (ARRL) affiliated group since February 1983.


ARRG, Inc. is an Oregon Non Profit Charitable Organization and we are a tax deductible 501 C 3 group.

147.040 and 442.225 repair project

  Here's the latest update on the Emergency Antenna Fundraiser

Located high up on the KOIN TV transmitter tower lives the 147.040 and 442.225 repeater antennas.

Feeding those two repeater antennas with wholesome signals are two 250' lengths of very low loss Andrews Heliax cables.

 Installed over a decade ago, the cables and antennas are getting old and crotchety. Earlier in 2015, the entire 442.225 antenna and hardline failed. Also, the 147.040 SWR‘s have been jumping all around which is also providing warning that it might completely fail as well.

 For the first time in ARRG’s 38 year history, there is a good chance that our engineers will be forced to pull the plug on one or both of these popular repeaters.

 Both repeaters are very important to our area’s Public Service Events and the following events could be affected by the lack of emergency repair;  Hood to Coast, Race for the Cure, Bridge Pedal and a probably a dozen other events.  

 Our team dislikes asking any of you for additional financial support without first doing all we can do to raise as much money as we could, first.  As many of you have noticed over the summer, our team has been putting in overtime in a last minute push to raise money to help cover the KOIN situation.  A small handful of your technical team members really went above and beyond this summer cleaning up estates, doing difficult tower work, setting up and running swap tables at Mic & Key, Rickreall, OMSI Makers Faire and SEAPAC - all in an attempt to raise funds so we wouldn’t have to once again approach the general membership with our hand out.

Even with all these efforts, the team was only able to cover the cost of the new Telewave antenna and some of the October 9th install bill.  Since openily fundraising, many of you have donated a $50 or $100 bill to the cause - thank you so very much. As of January 5th, 2016, we have collected close to 35% of our goal, so every little bit helps, either by just joining for $20 per year or adding any other tax deductable dontaion.

Cliff Soderback W7VVA
became a Silent Key on December 14th, 2015, after a battle with Cancer.
Cliff is survived by his wife, Marilyn of Sun City, AZ.

Whille living in Oregon, ARRG was lucky enough to snag Cliff as one of our Master Repeater Technicians. He used his vast Electronics Engineering skills to design and build many of ARRG's and other groups repeater controller and audio circuits - many which are still in 24/7 use today. The entire Amateur Radio Community has lost a great asset with the passing of Cliff.


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

Latest C4FM News

The C4FM System Fusion Page has been updated with a bunch of new repeaters


October 9th, 2015 442.225 Sylvan Work

A new 70cm Repeater antenna was installed today, however the antenna cannot be used because during the install, the tower crew found that the feedline is also bad.Currently, the 442.225 repeater is running on a temporary borrowed 450mhz antenna. The owner of that antenna has asked for it back as soon as possible.

 If we can't get new hardline purchased and installed before winter, the 442.225 might be forced off the air until next summer.

Cross your Ham fingers:)
