TrakBox & Yaesu G-5500 Connections
by Vincenzo Mone 01 Jun '14

01 Jun '14

Hi Folks, till now i 've used a Yaesu G-5400B Rotator interfaced with the Trakbox. I have changed the Rotator with a Yaesu G-5500. Since I have changed it, it seems that the Switch on the Trakbox that had to switch ON/OFF the rotator to turn them manually, does not work anymore. I mean if I switch it off to turn manually the rotators, they keep moving to the park Position after I made the movements. Anybody can tell me if the connections on the back of the Control Box of the G-5500 are the same of the ones on The G-5400B ? If yes which could be the problem? Thanks in advance. 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

LituanicaSAT-1 FM Transponder Report From Washington, DC
by Paul Stoetzer 01 Jun '14

01 Jun '14

Good evening, I heard the CW ID, voice message, and my own downlink briefly on a 6 degree maximum elevation pass in Washington, DC (FM18lv) at about 0058Z on 1-Jun-2014 until my receive was unfortunately wiped out by my preamp battery dying. Next pass at 0232Z is a much higher elevation pass and I will have my preamp battery charged! The station here is 2 FT-817s, an Elk handheld LPDA, and a High Sierra MIcrowave LNAA432 preamp. I was operating on my balcony with an excellent view of the southern horizon. I used Narrow FM on the uplink and that seemed to work out better for getting into the satellite than my last attempt on 1-May. Here is the audio from the pass: https://soundcloud.com/paul-stoetzer/lituanicasat-1-in-washington-dc-usa-fm… 73, Paul Stoetzer, N8HM Washington, DC, USA (FM18lv)

by Mike N8MR 31 May '14

Overview of the Livonia Amateur Radio Club Balloon Launch Balloon Designator : K8UNS Who? Club: Livonia Amateur Radio Club Club Address: P.O. Box 51532, Livonia, Michigan 48151-5532 Club Email Address: k8uns(a)arrl.net Club Web Site: www.livoniaarc.com Balloon Project Web Site: k8uns.org/high-altitude-balloon-project/ When? Morning of June 7th. Planning to launch between 9 and 10AM. If winds are an issue at arrival, we can notify all parties involved for a 1 hour postponement or cancellation. What? Payload Container Weight: 5lbs 4oz Dimensions: 14” x 10” x 10” Material: Rigid foam pink insulation wrapped with Ducting Foil Tape Payload Contents Beacon 146.46MHz FM 110mW voice beacon Identification and where to find more information ATV Transmitter 439.25MHz 1W Fast Scan television transmitter. Circular Horizontal Antenna suspended approximately 1 foot below payload box. Video overlay with current GPS Coordinates / Identifier / Speed and Direction APRS Transmitter 144.39MHz Packet Transmitter GPS Positioning with internal / external temperature, battery voltage and identifier Current positioning via radio or via the web - http://aprs.fi/info/?call=K8UNS-11 Map View: http://aprs.fi/#!call=a%2FK8UNS-11 Why? Because we are Amateur Radio Operators and we love science. The ability to track a balloon at 100,000 feet, take photos of the upper atmosphere has furthered interest in our hobby and our club. This project has inspired many smaller, similarly related projects by members of our club. We’ve had more participation and interest in this project, than most other projects we’ve run. Clubs around Michigan and Ohio have heard about this launch and are waiting for the launch. We're interested in reception reports of our balloon. Send us a note a let us know if you heard our beacon or transmitters. Delivery System Balloon Kaymont 1200g Balloon Diameter at launch: 4.88 meters (16 feet) Ascent Rate: 5 meters (16.4 feet) / second Color: White Material: Latex Supplier: Kaymont Balloons, NY - http://kaymontballoons.com/ Parachute RocketMan 6.5 foot Diameter Cord 50lb breaking strength Nylon cord. The cordage is used to tether the balloon to the parachute, and from the parachute to the balloon. Three feet from payload to parachute and 5 feet from parachute to balloon. Where? Because of the changes in winds, final launch location will be decided 12 hours prior to launch. Winds will be re-checked the morning of the launch, and a “Go Ahead” will be determined then. A final analysis of ground based wind-speed will be the final “Go/No Go” deciding factor upon arrival at the launch site. Our prediction tool (http://predict.habhub.org)only goes 180 hours out from the present time, so you may have to adjust the dates in the predictions below.
