Welcome to ARRG
and the
K7RPT Repeater System

The Amateur Radio Relay Group, Inc. (ARRG)
is an Oregon Non-Profit 501C (3) public service organization. ARRG owns and operates
the twenty different VHF and UHF repeaters that make up the K7RPT system. The repeaters provide communications coverage to about most of the populated areas of Oregon and some of SW Washington State.

ARRG was founded in 1977 and we are currently celebrating our 40thyearrof providing quality repeater service to the Amateur Radio Community..
The K7RPT repeaters, IRLP and Echo link gateways have always been'open''and completely free to use, so long as you are a licensed Amateur Radio Operator and agree to follow our Repeater Use Policies. After you've enjoyed the use of the system for a few months, for a few months, please consider helping to maintain the repeater system by joining ARRG.  

The K7RPT system and/or site facilities are made available to many State, County and City based Emergency Service Organization and Response Teams. Groups that don't already own or operate their own repeater systems or who need specialized coverage, all use the K7RPT repeaters freely and without any cost. Groups like the Amateur Radio Emergency Services (ARES) group, Community Emergency Response
Team (CERT), Washington County Search & Rescue, Portland Mountain Rescue, Mountain Wave Search & Rescue and many other Neighborhood Emergency Response Teams call the K7RPT system home.

When the repeaters are not being used for an Emergency or for training purposes, any licensed Ham Operator is encouraged to use and enjoy the K7RPT repeaters.

ARRG believes in ‘Public Service through Technology’ and we operate three Worldwide Internet connected EchoLink VOIP nodes, 1 IRLP VOIP node.
We also own and operate an APRS Digi at Government Camp - Mt. Hood and the new South Saddle APRS Digi..
ARRG was chosen by Yaesu to be one of the few groups to be an official 'beta tester' of the new System Fusion FM/Digital system. The 442.225 at Sylvan and the new 442.350 at South Saddle are Portland's main System Fusion repeaters.

ARRG also provides a Radio Team for special events and that includes providing portable repeaters, dispatch gear and volunteers for events like the annual Hood to Coast and Portland to Coast Relay, Reach the Beach, Cycle for Life ride, Race for the Cure and occasionally for the Portland Marathon.

K7RPT Repeater Updates

442.350 + 100Hz repeater is now at Chehalem Ridge

 The repeater is a System Fusion Digital repeater, that allows both analog FM and the new Digital modes to work one same repeater (one mode at a time of course).

The repeater is set to operate in Auto Mode Select (AMS) mode for the next few months. This means that the repeater is usable by both Analog FM or C4FM Digi DN or VW users. After the system is upgraded with new cans, antenna, then we'll be turning off the Analog side and switching it to it's permanent VW (Digital only) mode, sorry analog FM users.

Cinder Butte News - We have to say farewell to Cinder Butte, which has been a great site over the last 2 years, but over the July 4th holiday, Marc, Tony and Josh will be moving the 147.040 + 114.8Hz repeater from it's current location on Cinder Butte up to it's permanent home on Grizzly Mountain, which will be about 1300' higher in elevation.

Warning to the Portland 147.040 users, you will occasionally hear the new repeater on the same channel all the way from Grizzly, so it's important to program your radios with both encode/decode CTCSS tones if you don't wish to hear the steamy signal from 125 miles away.

Through our wonderful partnership with the Hood to Coast Radio team, the low powered portable 146.720 - 114.8Hz, located up on Wickiup Mountain, is now part of the K7RPT Repeater System.

The repeater covers the Coast Range and is located on a ridge just East of Astoria, Oregon.

The repeater is now linked fulltime with South Saddle 147.320 system and carries the nightly ARES D1 Net all the way to the beach.


Timberline System has expanded via two new linked Central Oregon Repeater

Eagle Butte 442.225 + 114.8  located at Warm Springs and covers Hood to Bend. The site is at 3800' and linked f/t into Timberline 147.120.

We'll help you with your

Amateur Radio Estate and Electronics Gear cleanup!


We believe in helping families of Ham's who need help dismantling old ham shacks, taking down antennas and towers. Our team can usually do this without added cost to the estate. Please write us and let us know what your particular situation is. We'll be happy to send one of our technical team out to meet and discuss your needs and help you make a plan.


Our cleanup removal cost is offset by any and all equipment donations to ARRG. 100% of all equipment donated to ARRG, Inc. and is usually fully tax deductible. ARRG is an official Oregon Charity and operates under the IRS 501c(3) charter. Our team of experts will help you clean up a Shack and properly sell or donate your loved ones Ham and electronic gear to our fully tax deductible Amateur Radio Public Service team. Contact Marc Peterson, W7PM at for more information.

K7RPT Fundraising Help


We are looking for good used gear, Motorola repeaters and mobiles to use as linking radios, test equipment, wattmeter's, hardline, talkies, mobiles, bases, commercial and ham antennas and towers and even just tower sections, rotors, you name it, we can come pick it up, provide you an itemized tax deductible receipt and after some bench work and refurbishing - hopefully sell it to another Ham through one of our semi annual ARRG Swap tables at Rickreall and SeaPac.


Did you know that ARRG often donates some of the gear we take in to Disabled and New Hams that are low income or have other needs..


We are doing this all in an effort to replenish our depleted Emergency Repeater and Antenna fund. Unfortunately, over the past 2 years of several record breaking storms, several of our repeater sites and their antenna systems where damaged beyond repair. These damaged sites included the 147.040 at South Saddle, the 147.040 and 442.225 located at Sylvan (KOIN) and lastly the 145.260 on Mt. Fanny.


 We don’t like to ask for extra financial or gear donations, because each of you already support the K7RPT system with your annual dues and in your help maintaining the system, but Nature dealt us a couple heavy blows last year.

If you could help out throughout the year, above and beyond your annual dues, ARRG would really appreciate it. All donations go right back into the repeater fund and we don’t use it for anything else.

ARRG got a 596lb. Present

A huge “thank you” goes out to IT Tech Direct from Annapolis, MD for this wonderful donation of repeater equipment. This new gear will allow us to further upgrade and modernize the aging K7RPT Repeater system. This boon will be of great benefit to our Users and to the many ARES, CERT and SAR teams that rely on the K7RPT Repeater System.
