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
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
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
* The TASS-SHIELD board for use with an Arduino Mega 2560
microcontroller. The TASS-SHIELD allows up to four TASS-R boards to be
Both boards are available now from TAPR as kits.
They use through-hole
parts and don't require any special assembly
The final component is open source software for the Arduino that
an interface between a host computer or other input system, and the
switching hardware. The software is available for download from TAPR.

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.
