Welcome to ARRG and the K7RPT Repeater System
Supporting the Emergency Radio Responder in all of us!

The Amateur Radio Relay Group, Inc. (ARRG) is an Oregon Non-Profit 501C (3) public service organization. ARRG owns and operates the eighteen plus VHF and UHF repeaters that make up the statewide K7RPT Repeater system.

ARRG provides professionally built communication repeaters, radios and support at no cost to the Amateur Radio Community, members of the Amateur Radio Emergency Service and Community Emergency Response Teams, Mountain Wave Search & Rescue, Washington/Multnomah County Sheriff’s Office Search & Rescue. Oregon Emergency Management and hundreds of Emergency Radio First Responders during time of need.

 Our system ARRG’s repeaters are located on mountain top repeater sites, many of which are co-located on Broadcast Radio/TV towers and hardened Public Safety sites around the state.

ARRG supports many Public Service events in the community. We do this by setting up and operating portable repeaters and dispatch gear for events like the Hood to Coast and Portland to Coast Relay, Reach the Beach, Cycle for Life ride and Race for the Cure events.

ARRG was founded in 1977 and we are currently celebrating our 42nd year of providing quality repeater service to the Amateur Radio Community. We provide our repeaters and technical expertise free to the community and to any Emergency Services group which needs communications. ARRG survives solely on your tax-deductible donations, so consider supporting ARRG by clicking on the 'donate' button below.

If you are New to Amateur Radio or just new to ARRG and the K7RPT Repeater System, our technical team members are here to assist you by answering questions, chatting up your Ham related questions and generally going above and beyond by providing you in person help and support.

November 1st, 2019: Changed the Sylvan 444.400 back to our old frequency of 442.225 + 100hz and the Quantar was swapped back out to the Yaesu System Fusion Repeater (which is running in AMS mode).

The 444.400 Quantar Experiment has ended. It did help reduce the adjacent channel interference to a good degree, however, we were still getting squelch crashes on the Motorola. The TV station (whom we share antenna space with) added two new high powered digital repeaters for their field users and we learned that their output on 450.025 and 450.050 was near our input on 449.400. Our three antennas are also just a few feet apart on the tower. As soon as we changed frequency and retuned our duplexers down to 442.225, the noise went away. We plan on keeping 442.225 as the defacto repeater frequency from this point forward. We are sorry for any inconvenience.

September 24, 2019: Tonight, with the help of KF7JCK and KI7AML, the Sylvan 444.400 repeater, which is a Yaesu DR2X FM/C4FM machine, was swapped out to a Motorola Quantar. We did this as a test to see if the loud white noise and squelch tail crashes would go away, by using a higher quality, tighter RX front end repeater. The Quantar appears to be working well, but might need a bit of touch up tuning, as the Quantar seems to have less sensitivity compared to the Yaesu we replaced it with. Obviously, there is no digital available on 444.400 while the Quantar test is going on.

September 20, 2019 -  K7WW, W7JDT and W7PM travelled to Timberline to work on the ailing 147.120 repeater system. We found the panel antennas to have a pretty high SWR of 1:8:1, so we installed a single bay VHF loop antenna facing Portland, which the repeater will run on for the next week or so.

KE7CF and W7PM plan on going up to the site again on 09/26/2019 to install a new set of cans (duplexers) and replace coax the mice have chewed through. We intend to go ahead and hook back up to the higher gain wall mounted panel antennas, even with their higher than usual SWR. They simply have more gain and consist of two co-phased bays looking South into Bend and West into Portland.

Sept 17, 2019: Better and some worse news for the South Saddle site - Sometime next week, the new 442.325 South Saddle Commercial Antenna and an even newer 100-Watt Motorola Quantar replacement should be here. The bad news is that thanks to the electrical contractor who installed the new power line a couple months ago, we no longer have access to the ARRG owned and operated. We have written a complaint to the property owner and CC'd the new lessee who is behind the bad decision to place it out in the way of our access. We are begging them to please relocate the service just 8 more feet back away from the building while there is still time to do so. The new WCCCA radio site, tower and antennas are not even installed yet, so it is still possible for the contractor to go in and fix their mistake.
