SCS PTC2 PRO SCS 3020 Radio Modem 

Send email, transfer files, establish real-time data links. The PTC-IIpro modem is the multi mode data interface between your PC and radio equipment. The PACTOR-II mode is the industry standard, and the most robust digital mode available for radio data connections. The PTC-IIpro will maintain links in conditions with signal to noise ratios of minus 18 dB, transferring data with absolutely inaudible signals.

The PTC-II-pro comes standard with 2 MB of RAM for incoming data storage, integrated RS-232 and TTL interface for control of common radios and a temperature compensated crystal oscillator for stability. The PTC-IIpro incorporates an audio amplifier for output to a speaker or headphones, which allows the PTC-IIpro's powerful DSP to be used with any audio signal. Built-in ability for GPS position reporting. With the optional Packet-Radio modules, the PTC-IIpro will function as a VHF/UHF modem (up to 19200 baud) and act as a bidirectional gateway for data between HF and VHF/UHF radios.
