Haiti related SATCOM frequencies
A number of SATCOM frequencies became busy after the Haiti earthquake:
RFSPACE SDR-IP is out now!
My buddy Pieter announced the SDR-IP is working and the first ordered devices are on their way to the customers. This software defined radio is more than just "RF in - IP out":
"The high performance SDR-IP is an internet protocol (TCP/IP) software defined receiver. It offers the ultimate versatility for scientific research, radio astronomy and shortwave listening. The SDR-IP uses a high performance 80 MHz, 16 bit ADC with both dithering and randomization for best performance. The output I/Q bandwidth is configurable via software. PC communications are handled over a 100 base-T port using 24 or 16 bit I/Q words." more..
