The SCS Tracker / DSP TNC is worldwide the first Terminal Node Controller using a Digital Signal Processor (DSP) as protocol and as modem processor. The close relationship between the hardware level and the higher protocol levels opens the possibility for unique applications.
The highlights of the modem implementations in the SCS Tracker / DSP TNC:
Generally
very reliable and flicker free DCD achieved with special DCD algorithms
on the signal processor.
New
developed multi-detector for 300 Bd AFSK. The signal processor automatically
processes a frequency range of ±400 Hz looking for 300 Bd transmissions
and receives all detected signals in parallel. Exact tuning by the user
is not necessary any more as a perfect tuning on the receiver side is
always achieved automatically.
Special
transmit- and receive filters for 1200 Bd AFSK, to avoid adjacent channel
interference and degradations by AC hum.
Adaptive
DC-removal by the signalprocessor at 9600 and 19200 Bd Direct-FSK.
The
Tracker / DSP TNC comes standard with a temperature compensated crystal
oscillator for stability. Built-in ability for GPS position reporting.
Packet-Radio operation for VHF and UHF up to 19200 baud.
Easily
installed with compatible radios from Icom, Kenwood, Yaesu, SGC, SEA,
Furuno, R&S and others.
