HF Transceivers
AMSAT/TAPR
Collaboration between AMSAT and TAPR has made avail-
able new modules for their progressive High Performance
Software Defined Radio (HPSDR) project. The new modules
include the Mercury, a high speed direct sampling front end,
the LPU power regulator board and the Pandora custom enclo-
sure kit. All hardware and firmware is open source allowing
modification by the experimenter. The modules operate via PC
control using a special version of PowerSDR software. With
the modules currently available, the setup can operate as a
1
⁄2
W high performance transceiver from dc to 60 MHz.
FlexRadio
FlexRadio Systems has added a new model to their line of
high-performance software defined radios. The new Flex-3000
HF and 6 meter transceiver is a compact 100 W transceiver
nicely sized to pair with a laptop PC. This makes a great com-
bination for travel or a compact home setup. The ’3000 shares
the software and performance of the larger Flex-5000, but
doesn’t have the cabinet capacity to be expanded with acces-
sories such as a second receiver. For more information see
www.flex-radio.com
In addition to new hardware, FlexRadio Systems has devel-
oped a new more visually appealing version of their PowerSDR
radio operating software.
ICOM
ICOM introduced their new IC-7600 HF and 6 meter transceiver,
a radio that brings a number of enhancements borrowed from the
very successful up-market IC-7700 and ’7800. The IC-7600 uses the
virtual meter that stunned us on the ’7700 and ’7800. In addition, it
offers improved near-in dynamic range through the use of three roof-
ing filters, the narrowest at a width of 3 kHz.
