The SSTV1 Modem software is an AFM modem that runs on the TAPR/AMSAT
DSP-93 hardware platform that can be used to receive and transmit Slow
Scan Television(SSTV) signals.

Version 1.0

Features:

- AGC function on input samples.
- I and Q quadrature signal components generated with Hilbert Bandpass
      filters.
- Digital complex PLL used for obtaining input frequency information.
- SSTV encoding using a phase coherent modulation of a numerically
      controlled oscillator.
- Automatic CW callsign ID after picture transmission.
- Communication with modem uses 38400bps serial data using DSP-93 UART. 
- Uses JVFAX(7.0 or 7.1) for user interface and various picture format
      conversions.
