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  18 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 41st year of 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, 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 System Outage Reports and Recent Repairs

September 11, 2018 Update
Unlicensed Radio Interference to Sylvan 442.225 - changing from DCS back over to 100.0Hz
For the past three weeks, ARRG has had several monitoring stations listening from all over the Metro area on 447.225 on the 100Hz tone.
We have been unable to capture or hear any of the unlicensed users from any of these locations.

This doesn't mean that the unlicensed users are gone, in fact, they might be located further outside of the Metro area and too far for us to listen and record them.

At the Sept 10th, ARRG Board meeting, it was decided to change 442.225 and 444.400 back over to 100.0Hz tone (the tone we have filed with ORRC and Repeater Directory. While there might be occasional interference, it is hoped that by listening in, we will be able to figure out what company they are with, or glean onsite into their location. If you hear the users, please don't engage them, rather listen to see if they mention a company name, user names, location, etc, and report your findings to

August 20, 2018: Pendleton Update
The Pendleton GE Mastr 2 we took off the site in April has been aligned and tuned by several techs, without much improvement. The repeaters audio still sounds muddy and off frequency, so it is very possible that the unit has leaking caps; as it is quite old.
The tech team has decided to retire the repeater and will be looking for a Micor, MSR or MSF replacement in the coming months.

April 5th, 2018: New 'temporary-low powered' Pendleton 145.330 Repeater
On April 5th, 2018, Marc Peterson, W7PM travelled to the Pendleton Repeater Site (Deadmen Pass) and installed a low powered ICOM repeater. The repeater is the same frequency as before 145.330 TX and 144.730 RX, and has a PL tone of 103.5Hz.
The main repeater is still in Portland being diagnosed, however, it does not look to be repairable, or would serve us well, even it were fixed for the time being.

Upcoming ARRG September 2018 Events

For it's 5th year in a row, along with the W7PM Events Team, ARRG is once again sponsoring the 2018 'Amateur Radio Exhibit' at the Portland Mini Makers Faire @ OMSI on Sat/Sun Sept 15th and 16th,from 0900-1700hrs both days - Volunteers needed to fill multiple greeting/teaching and station operation task on both days.

We also need people to come on Friday and help set up (design at the last minute) the booth and later on Sunday, to help us tear down everything. Please email Marc at if you can help on one or both days. All volunteer receive a free two-day wristband giving you access to the entire Fair and OMSI. Volunteers are always giving several hours off to go check out the fair!

Thanks to all the booth volunteers and helpers, like Dale, Mary, Tony, Marc, Russ, Rick and Brian.

June 12, 2018 South Saddle RF Power Raise

After running the new Quantar repeaters we installed at South Saddle in April 2018 on low power during the initial 'burn-in' period, on June 12th, Marc Peterson, W7PM,  visited South Saddle and using sensitive service monitoring equipment to check for receiver desense, Marc was able to raise both the .320 and .325 RF Output power to 80 Watts. It should be noted that both Quantar's are rated for 110W continuous duty.

May 6th, 2018:   New South Saddle System is on the Air!

After tearing down all the old cabinets and removing our 37 y.o gear, the new Motorola Quantar repeaters; 147.320 + 100Hz and 442.325 + 100Hz are now on the air. Unique dualtone, very low unobtrusive courtesy beeps have been added and 320's beep is lower in frequency at 400Hz while 442.325 has a 600hz beep, which helps those wondering which repeater they are actually working. This is a big plus to drivers who operate on the road.

 New Amity Hill Repeater on the Air

On May 1st, 2018, the 444.125 + 100Hz repeater was installed at the Tandem Hill Winery. This repeater is linked fulltime to the South Saddle System and covers from Amity, to Spirit Mountain Resort and towards Lincoln City on the Coast.

Monthly ARRG Breakfast Meeting
The monthly ARRG breakfast get together meetings are a great place where you can meet & greet other Hams, learn about Radios, Antennas, Feedline, Repeaters and Emergency Preparedness!

after 5 years of ARRG Monthly breakfasts, any scheduled upcoming breakfasts have been cancelled. Unfortunately, Marc is unable to host them any longer and nobody from the ARRG Board is available to fill in.

If an ARRG Member wants to fill in as host, we would love to see this tradition continue and will try to participate and help out as much as possible.


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.
