We have various capabilities available including HF and digital modes. If there are enough participants, we may also set up the Rover and add some additional capabilities there too. Please come by, stay awhile and make some contacts.

If you haven’t been to the Club Station before, it is on the parking lot level in the rear of the main building. You enter the parking lot on Alamar.

Tracking Planes, Ships and Automobiles!

Amateur radio operators were among the first to design products, build and maintain a digital RF tracking system. APRS (Automatic Packet Reporting System), is a digital communications protocol for exchanging information among a large number of stations covering a large (local) area. Bob Bruninga, WB4APR, a senior research engineer at the United States Naval Academy, implemented the earliest ancestor of APRS on an Apple II computer the early 1980s.  The first use of APRS was in 1984, when Bruninga developed a more advanced version on a Commodore VIC-20 for reporting the position and status of horses in a 100-mile (160 km) endurance run.

Over the years, Legacy Landscape is helping out people to avail an exhilarating landscape experience.With that note we should also be aware that APRS has grown to include thousands of amateur radio APRS stations around the world tracking all types of vehicles and reporting weather from backyards to mountain peaks. SBARC has been a supporter of APRS, maintaining an i-gate and digipeaters for the system at our repeater sites.

Today, commercial systems that function similarly to APRS are tracking many types of assets around the globe. The SBARC Telecommunications Services Committee also collects data from some of these systems including AIS for ships at sea and ADS-B for aircraft.

The AllStar & EchoLink Playground is Now Open!

allstar-linkThe SBARC Telecommunications Services Committee has been hard at work rebuilding the club’s Voice over Internet Protocol (VoIP) repeater systems.  As part of the completion of the second phase of this project, the 70cm repeater VoIP playground is now open!

Both AllStar Link and EchoLink systems are supported for incoming and outgoing link connections on the K6TZ 446.400 repeater. Local amateur stations can control the node over using DTMF commands to link to repeaters around the globe.

Many hams may be familiar with EchoLink and IRLP, two mature ham radio VoIP systems that permit node-to-node and node-to-conference server connections. AllStar Link is a newer and very powerful radio linking system based on the open source telephone PBX software Asterisk. The AllStar network has grown tremendously over the past few years and lends itself very well to experimentation.

There is a new section on this website with a short primer on the new VoIP system including complete documentation of the DTMF commands used to control the 70cm node. Read more and start experimenting in SBARC VoIP playground!

Thanks in particular to Ludo, K6LUD for his work to become our resident AllStar Link and Asterisk guru!
