[. . . ] In most systems the accuracy of the single frequencies has to be within +1/-1. 5% of the nominal value. If a DTMF call is received, the call sign is displayed on the monitor. In the Options menu a Time stamp function can be enabled to add date and time to each call.

The radio channel is used by a DUP-ARQ system in the same way as a simplex system, both stations alternating in transmitting blocks of five characters and a Hamming checksum. If a transmission error occurs a repeat request is initiated and the last data block is re-transmitted. If only one station is sending data, the other station transmits an IDLE pattern and initiates RQ cycles in case of transmission errors. Before transmission starts, the best available shortwave transmission channel is selected and its quality is continuously checked for the duration of the transmission. Within a given frequency range the system may select one of 5 possible channels which are spaced at 400 Hz intervals. Because of this channel selection mechanism, the two linked stations may transmit at different frequencies. The polarity of the bit stream (upper sideband (USB) or lower sideband (LSB)) cannot automatically be derived from the signal. Polarity inversion does not cause a loss of signal synchronization. 136 Transmission Modes WAVECOM Decoder W61PC/LAN Manual V6. 8. 1 DUP-ARQ-2 Parameter Frequency range System Speed Modulation Receiver settings Input-Type(s) Additional Info Value HF FSK, Duplex ARQ 250. 0 Baud FSK DATA, CW, LSB or USB AF, IF ITA-5 with block coding DUP-ARQ-2 is a further development of the DUP-ARQ system and the system characteristics are very similar. DUP-ARQ-2 allows transmission of ITA-2 (Baudot) or ITA-5 (ASCII) characters depending on the application. Each of the two blocks contains a 5 bit checksum (inverted Hamming) for error detection and a single bit for the global parity (odd parity). Special blocks defining IDLE, INTERRUPT and other special functions are transmitted. For these blocks the two normally unused bits specify the particular special functions with the combinations "10" or "11". Before transmission starts, the best available shortwave transmission channel is selected and its quality is continuously checked for the duration of the transmission. Within a given frequency range the system may select one of 5 possible channels which are spaced at 400 Hz intervals. Because of this channel selection mechanism the linked stations may transmit at different frequencies. DUP-FEC-2 Parameter Frequency range System Speed Modulation Receiver settings Input-Type(s) Additional Info Value HF FSK, Broadcast/Duplex FEC 125. 0 and 250. 0 Baud, variable 30-650 Baud FSK DATA, CW, LSB or USB AF, IF ITA-5 with block coding DUP-FEC-2 is a further development of the DUP-ARQ-2 system and the system characteristics are very similar. DUP-FEC-2 allows transmission of ITA-2 (Baudot) or ITA-5 (ASCII) characters. For error protection a five bit CRC-sum (inverted Hamming) and a single bit for global parity (odd parity) is used. As is the case with other full duplex systems transmission simultaneously takes place on two different frequencies.
