Now Available: The TASS Computer-Controlled Switch System
by Mark Thompson 28 Sep '15

28 Sep '15

Now Available: The TASS Computer-Controlled Switch System The TASS (Totally Awesome Switch System) is a general purpose 8-port DC-150 MHz relay-based switch. The hardware is designed to be very generic, with an inexpensive processor such as an Arduino providing the system logic. Control is via USB, with Ethernet and other interfaces also available. The TASS can be configured several ways, and multiple boards can be combined to create large switching systems. The TASS has many uses, from switching signal sources on a test bench or in a laboratory, to selecting receive antennas and filters in a ham or SWL station. The TASS system has two boards: * The TASS-R relay board, which does the mechanics of signal switching and provides a very simple 10-pin interface. * The TASS-SHIELD board for use with an Arduino Mega 2560 microcontroller. The TASS-SHIELD allows up to four TASS-R boards to be controlled simultaneously. Both boards are available now from TAPR as kits. They use through-hole parts and don't require any special assembly techniques. The final component is open source software for the Arduino that acts as an interface between a host computer or other input system, and the switching hardware. The software is available for download from TAPR. An introductory video is available at https://youtu.be/P-TUM2dOi4c or from TAPR at http://tapr.org/~n8ur/TASS/TASS_Intro_26Sep15.mp4 Software and documentation can be downloaded from http://tapr.org/~n8ur/TASS. You may order the TASS-R and TASS-SHIELD boards by visiting http://tapr.org/kits_tass.html _______________________________________________

TW-1A,1B,1C heard
by Mineo Wakita 27 Sep '15

27 Sep '15

I could receive the signals of these Chinese satellites on 27 Sep 2015. The signals of TW-1A or 1C in the left figure are a very powerful every 10 seconds. The signal of TW-1B in the right figure is a very delicate and I confirmed that are sending every 20 seconds. Because those protocol are CSP (not AX.25), we will not be able to decode them in the usual way. I used 2015-051A in NORAD as TLE. 2015-051A 1 40925U 15051A 15270.08999289 -.00000074 00000-0 00000+0 0 9992 2 40925 97.3119 305.5606 0012816 273.4021 164.9809 15.29495126 296 09:44-09:55 UTC, 27 Sep 2015, Ele 31 SE-E-N TW-1A/C http://www.ne.jp/asahi/hamradio/je9pel/50927twa.png TW-1B http://www.ne.jp/asahi/hamradio/je9pel/50927twb.png Details http://www.ne.jp/asahi/hamradio/je9pel/tw1a1b1c.htm JE9PEL, Mineo Wakita
