Arizona repeaters
This page will go into some detail about our linked repeaters, sponsored by the Superstition Amateur Radio Club, but first let's offer up some resources that will list the other repeaters available to us throughout Arizona.
Official Frequency Coordinator lists
Here are the latest repeater listings for Arizona from Arizona's frequency coordinator, with band-by-band listings updated as changes are made by each band's respective coordinator. Please also familiarize yourself with information provided on the frequency coordinator's home page: Arizona's frequency coordinator
These band-by-band listings come in PDF format, and for Windows users there is a free alternative to Adobe Reader, the faster, smaller Foxit Reader. With Ubuntu Linux, one doesn't need any additional software to access PDF.
One last note: If any of these files is for some reason not on the azfreqcoord server, you may see a "blue screen of death" titled, " General Protection Fault." DISREGARD and do not restart your computer! A check on January 5, 2008 reveals that the BSOD has been replaced with a more appropriate "Not Found" page.

Unofficial repeater lists
The frequency coordinators try to verify the existence of coordinated repeaters, but there may be some on the books that no longer exist, especially in remote areas. Some coordinators poll their repeater owners of record and gather other information in order to ensure the accuracy of the lists.
There is another site that lists repeaters throughout Arizona, with a report card on which repeaters are active and which are not. Check it out. The information is presented in an easy-to-use layout.
Please keep in mind that repeaters should be coordinated, and therefore will appear in the official lists above -- unless of course it's a brand new addition -- and that a coordinated repeater has FCC Rules in its favor in an interference issue with an uncoordinated repeater.
Repeaters of the Superstition ARC
August 25, 2008 update
The club maintains two repeaters in northeast Mesa, both linked together full time. A remote base is linked full time except during morning nets and the Wednesday Newsline Net. (For net info, please see the Club Nets page.) They are:
- 147.12 MHz: (+600 kHz shift) (162.2 Hz access)
- 449.60 MHz: (-5 MHz shift) (100.0 Hz access)
- 29.65 MHz: (Simplex) (100.0 Hz access tone)
The remote base is dropped from the link before the start of the weekday DriveTime Nets and before the start of the Newsline Net on Wednesday night. It is restored following the conclusion of the nets, all on an automatic timer.
The repeaters and remote base all operate under the club license, WB7TJD. An additional repeater located at Sky Harbor Airport, and owned and operated by KC5CAY, comes in from Phoenix over a simplex link on 900 MHz. it operates on 449.20 MHz with a Minus offset and a 100 Hz access tone..
Access information:
Each repeater transmits an access tone on its output, same as the one required to get in. This allows for tone squelch reception of the repeater, blocking unwanted intermod and noise. The tone is set to 0.5 kHz deviation, and "cannot" be set any higher. Many older radios with tone squelch features will not work, or will work with many drop-outs on this level of tone. However, many newer radios handle this tone setting well.
Courtesy Beep information
The Mesa repeaters, 147.12, 449.60 and the remote base on 29.650 all register low-pitch beep when traffic comes in on the 147.12 input, and a low-high dual-pitch beep when traffic originates on the 449.60 side.
Traffic on the 29.650 remote base input registers with a high-low dual-pitch beep on the Mesa repeaters.
Traffic from the Phoenix 449.20 repeater registers a high-pitch single beep on the Mesa repeaters.
Over on the Phoenix repeater, local traffic registers a low-pitch beep, while link traffic from the club system in Mesa registers a high beep.
A 180-mile Round Trip on 147.12
Thursday night, March 22, 2007, during the club net, on a wet, rainy night, Jim, K9ARO was checked in to our net from out Wickenburg way. He is a little south of the town of Wickenburg, about 90 miles northwest of WB7CRK in east Mesa. Larry noted the distance to the net, and said, "CQ Tucson," which is 90 miles southeast. Don, KD7UIZ in central Tucson came back, and he and Jim were able to exchange words over the 180 miles between them, through the repeater. Jim was running 5 watts from his RV, parked on some high ground, which was loud and clear, with some noise, but which started failing when rain hung out over the repeater site, raising static levels. Meanwhile, Don's 100 watts was very strong into the repeater.
