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.

147.040 and 442.225 Sylvan (KOIN) Tower update

Over the past few days the ARRG tech team and our tower contractor have been busy working on the repeater antenna upgrades. We replaced the aging 147.040 and the failed 442.225 coax with new 1/2" Andrews Heliax. The 040 users are already noticing an increase in signal strength.

We also installed a new Telewave UHF antenna for 442.225.
The team also installed a third Heliax run to a spare dualband antenna to use if either 147.040 or 442.225 antenna or coax gets damaged in the future.

The total cost of the project was over $6k. This hit was lessoned by the generous support of our members who donated over $2k towards project - thank you!

Losing the hardline and antennas at KOIN this past year wiped out our emergency repeater fund and even with normal annual dues, it's going to take years to rebuild.

We are still looking for help to rebuild the repeater antenna fund.

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
