SBARC/ATN Tech Question of the Day...
by rod＠sbatv.org 12 Jun '11

12 Jun '11

I know Sundays are lazy days, but I bet some of you are up to this challenge. As a practical matter, we have a problem with 990KHz energy getting into out cameras and video inputs at the ATV Repeater site. We can't filter out the interference since it falls right in the middle of the video spectrum. We're quite sure the energy is coming in on the coax, functioning as an excellent antenna, and couples into the equipment. Everything is bypassed properly, but that's not good enough. So here's the problem for you to solve. (We've tried torroids (even tuned to freq) and "hum" filters and they don't work!) 1. We want to loop the RG-59 (not RG-58) coax (look up the specs online) several times to provide 750 ohms of inductive reactance. Assuming we make several loops in the coax that are 4-inches in diameter (side-by-side), how many loops do we need? (Hints: The conductor diameter is the outside diameter of the shield and the spacing between turns is twice the thickness of the insulation on the coax.) When you have that figured out, try this. 2. We want to loop CAT5 cable (look up the specs online) several times to provide 750 ohms of inductive reactance. Assuming we make several loops in the coax that are 4-inches in diameter (side-by-side), how many loops do we need? (Hints: The conductor diameter is different than for coax. The pairs are twisted. The spacing between turns is a little different than for coax.) Have some fun with this and I wish you luck. Answers can be tested at the ATV Repeater site this afternoon.

ATV REPEATER - SPRING CLEANING TOUR AND WORK SESSION TODAY AT 1PM AND NOW FOR SOMETHING COMPLETELY DIFFERENT - If you want to do something a little different today, consider a trip up Gibraltar Road this afternoon to check out the ATV site and help with a few construction and cleanup projects. We need your help and it might even be fun. TRANSPORTATION - If you need a ride, call me ASAP at 637-0985. If you're driving on your own, contact me on the 146.19/79 repeater between 12:45pm and 1:00pm to coordinate access to the site. SHOWTIME - We'll be hooking up a trailer at Dave K9KBX's house at 1pm and then we'll drive to the repeater site, arriving around 1:30pm. OBJECTIVES - Build, learn and enjoy. Depending on the size of the crew, we'll try to accomplish these tasks. . Raise the 5.8 GHz receive antenna, peak it up and install the preamp . Install a 5.x GHZ WiFi Access Point pointing downtown . Install a 2.4 GHz WiFi Client Bridge pointing downtown . Install a Local Area Network Switch and Wireless Router . Get all of the computers talking to each other on the LAN/WLAN . Install an "on-the-air" Waveform Monitor so we can all check and adjust our ATV signals . Test and install our Tower Cameras . Load the Outdoor Rack onto the trailer and take it to Rod WB9KMO's house . General Cleanup of the building and surrounding area If you want to learn about these things or just want to pitch in and help, check in on 19/79 at 1pm. We may work until 5pm or so, but you can leave anytime you want. Even a little bit of your time will be a big help. Your participation is greatly appreciated. Rod Fritz, WB9KMO rod(a)sbatv.org 805-637-0985 "We look forward to seeing you on Amateur Radio real soon."

SBARC Field Day 2011 Presentations - We Need You to Volunteer
by rod＠sbatv.org 10 Jun '11

10 Jun '11

Hello SBARC Members and Friends, SBARC will participate in Field Day 2011 on June 25-26 at Camino Real Marketplace. We expect to have two operating stations, the primary station in the Rover and the GOTA station in the ARES Van. This year, we will focus more energy to promote public awareness of Amateur Radio and SBARC by making scheduled presentations from 9am to 3pm Saturday and from 9am to 2pm Sunday. In addition to the presentations, we'll interact with the public to answer their questions and promote Amateur Radio and SBARC. If there is enough public interest, we may keep our booths open as late as 5pm on Saturday. There will be a barbeque after the event on Sunday. We need volunteers to make presentations and to interact with the public. Please refer to the attached document and volunteer for one or more of the positions... We need some of you to make short presentations to be scheduled throughout both days. Here are some ideas you might consider. . Field Day Overview . Emergency Preparedness Overview . Public Service Overview . Video or Pictures of an Event . SBARC Facilities . Amateur Radio Satellite Contact . Mechanical Teletype Demo . Amateur Radio High-Altitude Balloon Demo . Amateur Radio on the Internet (ARRL, Websites, etc) . Equipment Demo (Show off your favorite project or radio) . Specialized Mode (SSTV, RTTY, PSK31) Demo . CW Demo (Spark Gap Transmitter?) . DX Demo (DXpedition) . Microwave Communication Demo . Mobile ATV Demo . Any other interesting Amateur Radio topic Please let me know where you can help so we can make a good impression. Thank you, Rod Fritz, WB9KMO SBARC OUTREACH Chair rod(a)sbatv.org 805-637-0985
