The AOR TDF370 DSP Multi-Media Terminal is so versatile it is difficult to know exactly what to call it. It does many different things around the ham (or monitoring) shack. This product was unveiled at the 2001 Dayton Hamvention. The AOR folks had an active demonstration of this product that was very impressive.
DSP Audio Filter
A total of 4 types of filters are provided for voice: FFT, LMS, Hi-Fi and BPF. For CW operators 3 filters are provided: BPF, LMS and Stereo filters.
PSK31 Operation
Each parameter can be set by a PC through the RS-232C port. The TDF is capable of displaying decoded signals on the LCD without a PC.
RTTY Operation
45, 50 and 74 baud, 170, 425 and 850 Hz shift AFSK.
SSTV Operation
Supports Robot 36, 72, Scottie 1, 2, Matine 1, 2, AVT90, 94 (optional control software is required and no display to LCD).
Microphone Equalization
Adjustable up ± 6 dB in 8 frequency bands. A background noise cancelling function is available.
Digital Voice Recorder
A digital voice recorder has been built in to record audio up to 102 seconds long using DPCM compression technology. There are 8 memory channels (total recording time is 102 seconds).
