From WINRADIO Communications:
Until recently, all computer-based wide-band receivers have been only available for the IBM PC and compatibles. Those radio users who prefer Apple have been left out. WiNRADiO is now rectifying this by introducing Apple Macintosh support for our most popular receiver, the WR-1550e, a medium-range external receiver with frequency range 150 kHz to 1.5 GHz (the US version excludes cellular frequencies 825-849 and 869-894 MHz). The standard WiNRADiO WR-1550e hardware is supported by native Mac software, which is able to run on older Mac models with serial ports, as well as new models with USB ports. Most Macintosh computers which use the PPC (Power PC) processor, i.e. the 'Power Mac' models produced beginning 1994, are supported. Earlier Mac models, using the 68000 family of processors, are not supported. For serial interface models, WiNRADiO provides a special serial cable to connect to the WR-1550e receiver. For the USB interface models, a serial-to-USB adapter is required. WiNRADiO recommends the Keyspan adapters, such as the Keyspan USA-19 model. This will be soon available from WiNRADiO.
What's new in this version:
This version improves reliability when running in 'Classic' mode on an OS X Mac. A symptom observed in the previous version was that the program could experience a port timeout and quit running. The timeout configuration for the USB to serial connection had not made sufficient allowance for OS X allocating time to other processes.
