For Sale - TrakBox Rotor/Radio Controller
by Robert Felt 30 Jul '08

30 Jul '08

Wednesday 7-30-08 To All: For Sale - "TrakBox" Satellite tracker, antenna rotor controller for stand alone operation. (JARL design, TAPR kit) The trakbox is a self-contained, stand-alone rotor/radio control for use with your satellite stations. Select the satellite you wish to track from a front panel control and the TrakBox will steer your antennas in both azimuth and elevation to track the selected satellite when it is or above your horizon. In addition, if you have a radio with a computer interface, the TrakBox will tune your transmitter and receiver and correct them for doppler shift. TrakBox is set up to directly interface to Kenpro, Emmoto, and Yaesu dual-axis rotators which include a computer interface. Trakbox includes a serial port to allow you to set the real-time clock (which is battery backed), your station location (latitude, longitude and elevation) and the keplerian elements for the satellites you are interested in (up to 40 satellites may be loaded, and the elements may be uploaded in ASCII in either the AMSAT or NASA formats). A two-line LCD display is updated every second, showing the azimuth and elevation of a satellite, along with the satellite ID and GMT. See Complete description and docs at TAPR web page: http://www.tapr.org/kits_trakbox.html I built this kit from TAPR back in the late 1990's. It provided excellent service. Still works fine. Asking $130.00, OBO Thanks, //Bob// Robert Felt --KB5YZG-- 1403 5th Ave West Hendersonville, NC 28739 tel 828-696-4103

by Robert Davis 02 Jul '08

02 Jul '08

Dear prospective lab volunteers, I've decided to enjoy Washington DC for the weekend of 4th of July. This is a change from my earlier tentative schedule. Sat July 5 - Closed Sat July 12 - Open 9-5 Sat July 19 - Open 9-noon (tentative); We're at the Salisbury Barnes & Noble for a kids' (& parents') technology day at 2pm! This outreach to kids is partially based on "A Dangerous Book for Boys" which mentions Morse code. Sat July 26 - Open 9-5 (tentative) For directions, map to the intersection of Pocomoke Belt & Broad St in Pocomoke City, MD 21851 (the actual address maps incorrectly). Or GPS N 38 03.381, W 75 33.651. I don't require (but do appreciate) an RSVP by email or phone. My cell is 443-783-7794. We've been working on the ground station plan and Eagle satellite mechanical design. I have materials for both that I can email upon request. 73 bob Robert Davis KF4KSS
