Features (or whatever you call it):
AM or FM demodulation possible, adjustable filter width (3 levels),
FM deviation adjustable for contrast adjustment. Uses the
system processor for signal processing (filtering, demodulation).
Grayscale reception with 64 gray levels
Most parameters (except the modem settings) can subsequentially
be adjusted (while or after the image is recieved), because the
demodulated raw data stream is kept in memory.
Image Polarity switch (pos/neg), Phasing polarity switch (pos/neg)
APT tone detection for automatic start/stop (both frequencies
adjustable), automatic phase-in (starts a new image)
Variable IOC for height/width adjustment, variable LPM
Writing direction horizontal/vertical up/down left/right switchable
subsequent image centering and LPM fine correction possible
automatic saving of received images as simple pgm-file
