Superstition ARC Repeater System Update Corrections:

April 18, 2010 update

The Stone Castle houses the 147.12, 449.60 927.7125 and the remote base on 29.60 MHz simplex.

Ownership:

Superstition ARC-owned WB7TJD/R: 147.12, 449.60, 29.60 Simplex Remote Base

These are co-located in the Stone Castle in northeast Mesa.

Actually, Dan, N0/FPE owns the remote base equipment, but made it available for club use. It was placed under the club's call because it had been tied to the club's 147.12 and 449.60 "V-U circuit at the castle," Brian advises.

Also, not a big deal, Brian noted, but the GE MASTR II repeater upgrades that are in use on the club's "V-U circuit" were provided to the club for its use and are owned by Brian, KC5CAY.

This equipment is made available for club use.

Links

U-V Network: 147.12 and 449.60 Linked Full Time
10-900 Network: 449.20, Phoenix, 927.7125 and 29.60 are linked full-time except during club nets.

During nets, 449.20 joins the U-V Network, 927.7125 is a stand-alone and 29.60 is off.

During Communications events these link-ups will change to fit the need.

Tone Access information

449.20, 449.60: 100 Hz
147.12: 162.2 Hz
927.7125: 151.4 Hz

Link Schedule

During Morning DriveTime Nets Mon-Fri from 6:50 AM - 8:10 AM:

147.12, 449.60 and 449.20 are linked
927.7125 is stand-alone, and 10m Remote Base is Off.

During Wednesday Evening Net Wed from 7:45 PM - 9:30 PM:

147.12, 449.60 and 449.20 are linked
927.7125 is stand-alone, and 10m Remote Base is Off.

At all other times, (subject to change during communications events):

147.12 and 449.60 are linked full-time.
927.7125, 449.20 and 10m Remote Base are linked full-time.

Link times may shift later as the repeater controller's scheduling clock loses time, requiring periodic reset by a control operator.

New Courtesy Beep Info

On the Northeast Mesa 147.12 and 449.60 repeaters:

Users of the 147.12 input cause the repeaters to emit a high-pitch single beep.

Users of the 449.20 Phoenix input during club nets cause the Mesa repeaters to emit the same high-pitched beep heard from 2-meter users.

Users of the 449.60 input cause the repeaters to emit a single low-pitch beep.

On the Northeast Mesa 927.7125 repeater and 29.60 remote base:

Users of the 927.7125's input will cause that repeater to emit (unknown).

Users of the 29.60 remote base input will cause the 900 repeater to emit (unknown).

Users of the Phoenix 449.20 input will likely cause the same high-pitch beep heard during nets on the 147.12.

On the Sky Harbor repeater in Phoenix:

Users of the 449.20 input cause the repeater to emit a low pitch single beep.

Users of the Mesa remote base on 29.60 simplex cause the Phoenix repeater to emit a higher pitch beep. It is very probable that any input in Mesa will cause the same beep.

I have been able to actually hear the 927.7125 repeater break the squelch on my scanner, with best results using a "BNC" elbow and "BNC-to-F" adapter, with no antenna from inside my mobile home. Things sure work differently up here than they do down below!

Following below is older information, last edited in 2008.

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.

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.

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.
