SBARC July General Meeting: DMR Radio Presentation
by Levi C. Maaia 05 Jul '17

05 Jul '17

*SBARC General Club Meeting* *Friday, July 21, 2017 @ 7:30 PM* *401 N. Fairview Ave. in Goleta* Imagine sitting in your living room using an inexpensive hand-held radio and making crystal clear, static free contacts throughout California, the United States, and the WORLD! This is not only possible, but it’s easy to do using Digital Mobile Radio (DMR). And, we’re doing this now, right here in Santa Barbara! This month, SBARC hosts a special presentation by *Michael Rickey, AF6FB* on the new and quickly growing DMR digital voice mode. Michael will give us a demonstration on how DMR works and explain how the PAPA system is supporting a build-out of DMR repeaters in Southern California, making it easy to stay connected to the network throughout our region. DMR is unlike most other digital voice modes used on VHF/UHF FM in amateur radio as it is supported by several major radio manufacturers including several low-cost imports commonly used by amateurs. DMR networks can be accessed from repeaters here in Santa Barbara and also through home-brew and *professionally built hotspots* <http://www.grapevineamateurradio.com/store/?model_number=Openspot1>. You can get on the air with DMR with a *Tytera MD-380 HT for as little as $80* <https://www.gigaparts.com/tyt-md-380.html?&utm_source=EMAIL&utm_medium=MD38…> and access thousands of talk-groups around the world and even chat with fellow SB hams dabbling in digital on our very own SBARC DMR talk-group. Most DMR repeaters can access the same talk-groups available on any other repeater. So no mater where you travel, you can radio home. DMR also uses TDMA to support multiple users per FM repeater pair and at 12.5 kHz wide, it is far more efficient than traditional analog wide-band FM. *SBARC General Club Meetings are held at the Goleta Union School District, 401 N. Fairview Ave. in Goleta, right across the street from the Goleta Library. Doors open at 7:00 PM and the meeting starts at 7:30 PM. Put the date on your calendar and bring a guest!* *[image: Inline image 2][image: Inline image 1]* *Michael Rickey, AF6FB*

The AllStar & EchoLink Playground is Now Open!
by Levi C. Maaia, K6LCM 07 Jun '17

07 Jun '17

The 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 the SBARC 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! Levi C.

SBARC has a new open Yaesu System Fusion (YSF) repeater on a digital repeater test pair located at the Club’s La Vigia Hill Mesa site in Santa Barbara! You need not be a member of SBARC to use this digital-only repeater. Anyone with access to a System Fusion radio available may tune to the K6TZ YSF test pair: YSF Repeater Transmits / You Listen: 449.46250 YSF Repeater Listens / You Transmit: 444.46250 Signal and coverage reports are welcome. Please email the telecom team using the form at: https://www.sbarc.org/contact-us/ Please note: the WB6OBB 449.400 repeater (formerly testing System Fusion) is presently offline and will return soon as an analog FM-only repeater atop Broadcast Peak.

lumber rack help ASAP
by Ken Alker 11 May '17

11 May '17

A team of us are heading up to Broadcast Peak Saturday morning to replace the antennas for all three of the WB6OBB repeaters. We could really use someone who has a lumber rack to transport a 20' pole along with some other not-as-long poles. Does anyone out there have a truck with a lumber rack, or a loaner vehicle with rack, a rack to loan, or a friend with a rack who might help out by driving his/her vehicle or lend out their lumber rack? Other ideas accepted. Borrowing a trailer would be next best but would be tough to get up there due to tight curves and a little tough terrain. Ken KA6KEN 685-2030 Sent from my iPhone

Calif. AB 1785 - Hand-free driving and amateur radio
by Levi C. Maaia, K6LCM 04 May '17

04 May '17

SBARC Members, Did you know that using your mobile radio while driving is now illegal in California as of January 1, 2017? California’s Distracted Driving Law Assembly Bill 1785 was passed in 2016 and went into effect on January 1 as California Vehicle Code 23123. The law was designed to curb smartphone texting while driving which has been identified as a safety hazard. However, the ambiguous language in the law has also unintentionally rendered all commercial and amateur radio two-way mobile operation illegal in California. In nearly 70+ years of two-way radio technology there are zero documented cases of such operation being any known threat to public safety or operation of a motor vehicle. Here is a very comprehensive news story that very succinctly summarizes the issue: http://sacramento.cbslocal.com/2017/03/20/two-way-radio-users-worried-calif… The original author of AB-1785, California Assemblyman Bill Quirk (Assembly District 20) has confirmed that the law was not intended to ban amateur radio mobile operation and the California Highway Patrol has confirmed its support for continued use of of mobile amateur radio (see attached memo from CHP). However, the fix being considered this week on the floor of the State Assembly (known as AB-1222) does not completely codify Assemblyman Quirk's own Legislative Analysis nor a recent CHP memo supporting two-way radio operation. AB1222 goes to the Assembly floor for vote SOON and it *MUST* be fixed first! I am writing to urge you to consider contacting Santa Barbara's Assemblymember Monique Limón at her Sacramento office (916) 319-2037 and encourage her to support revisions to AB-1222 to specifically permit radio amateurs to once again legally use mobile radios while driving. You can find more information and language to use on your call here: http://www.no1pc.org/handsfree/index.htm You might also consider signing this petition: https://www.change.org/p/correct-ambiguities-of-ab-1785-cvc-23123-5-cellula… Meanwhile, the CHP memo is not a Get-Out-Of-Jail-Free card. It is non-binding and not applicable to local law enforcement agencies. However, you might consider printing the attached copy of it for your glovebox for whatever it is worth until this vehicle code is corrected. Thank you for your consideration, Levi C. Maaia, K6LCM

SYP antenna test
by Bill Talanian 24 Apr '17

24 Apr '17

To: All From: Bill Talanian Subject: SYP two-meter repeaters For the next week or so you may notice a loss of sensitivity of the 145.18 repeater. The antennas between 145.18 and 145.16 were switched. Initially it appears that the noise floor and in-band signal interference follows the antenna system, not the equipment. The "good" antenna will be reconnected to the 145.18 system on the next visit to SYP. Following that a concerted effort will again go back to the antenna and coax in question and its location on the main tower

TNC Install
by Bill Talanian 19 Apr '17

19 Apr '17

Folks: I'm looking for one or perhaps two people to go to Santa Cruz Island and install a mobile radio in their Safari Truck. They have all the basic parts but the installer must have small hand tools and perhaps items for splicing power wires and the usual hardware for bracket mounting and roof top hole etc.. The boat usually arrives 1130 AM and departs at 1430 so not enough time to do it all in one day. This may require an overnight stay and depart the following day. If anyone has experience with mounting mobile transceivers and antennas let me know. All of this must be worked out with the TNC to ensure the schedule is other than a black out day when other visitors are on the Island. Bill Talanian

Happy World Amateur Radio Day
by Levi C. Maaia, K6LCM 19 Apr '17

19 Apr '17

Every April 18, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on that day in 1925 that the International Amateur Radio Union was formed in Paris. Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was “in grave danger of being pushed aside,” the IARU’s history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide. Read more: http://www.iaru.org/world-amateur-radio-day.html LCM Levi C.
