Welcome to ARRG and the K7RPT Repeater System

K7RPT June 2018 MAP

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 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.

ARRG and K7RPT News

December 17, 2018

The 147.380 Cedar Mill repeater is no longer part of the Beaverton CERT Radio plan and the system (which includes the K7RPT-R Echolink node) is now available for all to use. Unfortunately, the linked Cedar Mill 443.750 repeater died in November, so it was brought down from the site, so W7PM's team can look it over. There's no repair timeframe, but there is word that the 443.750 might be moved out to K7PN's tower in Sandy, Or, at which time it will be linked fulltime to the 442.225 Sylvan System.

We are still hearing the Unlicensed Radio Interference on Sylvan 442.225. It seems that the radios are being used on our input 447.225 frequency around 800-830 a.m. almost every day. Please
help us in our ongoing monitoring efforts by adding our input frequency to your radio or scanner. Simply add 447.225 (simplex) with a 100.Hz full encode/decode tone into one of your radios.

The Chehalem 444.400 + 100Hz repeater is down right now. W7PM has it in his shop and it will be used as part of an upcoming technical training class. It needs to be fully re-aligned and a different controller wired, programmed and installed on the unit, before putting it back up on the site. In the meantime, the 442.350 + 100 Hz System Fusion (AMS) repeater was installed in place of the vacant 444.400. It is not linked and is open to everyone, both Analog and C4FM users.

October 16th, 2018

The new 4 bay antenna for the Astoria 146.720 (Wickiup site) was installed and is working well. Unfortunately, there is a link antenna issue, so the 146.720 will stay unlinked from South Saddle for the winter.

October 16th, 2018  Injured ARRG Team Member
Since dozens of you have called and written asking about our team member and how an accident
 like this could have occurred, here are the details as we know them.

ARRG and the HTC Radio Team is sad to report that one of our ARRG technical team members was severely injured when a Harness broke/failed and the member fell a significant distance while he was trying to maintain the newly installed HTC Radio tower.

According to witnesses and the victim, while using a borrowed climbing harness to tighten the newly installed 30' Hood to Coast tower bolts, apparently the safety harness rope line used to add a secondary attachment to the tower failed and complete slipped out of the D ring it was attached to. This single failure in turn caused too much pressure on the other side of the safety hook and both safety hooks slipped through the loops before the climber, nor his tower helper could react. This resulted in the rest of the safety harness to come unattached, which then resulted in our team member falling from about the 20' level of the tower.

Unfortunately, during the fall, our member hit the roof of the radio building, knocking him unconscious. Nearby tower helpers who were poised on the roof tried to grab the falling team member, but were unable to do so. The team member summersaulted over the building and then fell another 10' to the ground below. The team member suffered head and mouth lacerations, plus couldn't move well due to possible neck and back injuries. Other team members provided First Aid while still at the Radio Site. The team member was transported to the Columbia Hospital in Astoria Oregon.

It was later learned that our team member required stitches in both his head and also his tongue, because during the fall he had bit through his tongue and also chipped several teeth. It was a couple hours later that we heard that our team member had broke his back, crushed several neck vertebrae and also crushed a disc in his lower back.

December 10th, 2018 update: We are happy to announce that the ARRG Technical Team member who was injured during the fall from the HTC tower is doing a bit better. He is finally up and walking more, but still has a long way to go to get back to normal life. Unfortunately, his ongoing back pain and worsening neck pain ,makes it hard for him to work on repeaters or do any hand coordinated tasks like soldering, so he wants us to know that for the time being, many repairs and upgrades to the K7RPT Repeater system are on hold.

October 14th, 2018

A new Motorola Repeater was installed on Mt. Fanny (above LA Grande). The new repeater is already better and more sensitive than the 35 year old Micor Mobiles it replaced.

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.

ARRG @ SEAPAC Convention 2019
ARRG will be at the 2019 SEAPAC Convention, which will be held in Seaside, Or.

The New South Saddle System is still going strong!

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.

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.
