Important Notice !
The 'Wired & Tested' RASCAL, contains; high quality components and design:With the
RASCAL, the PC Sound Card and RS-232 comport (used for automatic PTT), are ISOlated from the transceiver by special optical isolators, and transformers designed for this application. The LINE IN and LINE OUT cables are high quality, shielded cables with a high permeability ferrite choke molded into the cable. This ferrite choke provides an increased degree of immunity from potential ground loops and RF feedback. To further reduce the effects of processor interference, the RS-232 cable used for automatic PTT via the PSK and SSTV software, is a high quality, well shielded, 6 foot cable utilizing both foil and drain wire shielding. A level control is included to adjust the transmit audio to the transceiver.The "RASCAL"™ does NOT require 'wall-warts,' or external power supply transformers.
The "RASCAL" is ideal for portable and field-day operations.
The "RASCAL" can be easily used with portable computers.
The "RASCAL" kit Includes: Case, Cables, Connectors, Components, and Custom made printed circuit board.
The "RASCAL" KIT is $25.00 (price includes USA shipping, and Disk of PSK programs.).
