[. . . ] By selecting the All frame headers option, all frame headers are displayed regardless of the message type. In case of a parity-error the data transferred in the related data word are displayed in red characters to indicate a potential error. RTCM v. 2. 0 and 2. 1 are not completely compatible, but both systems are used. More detailed information may be found in "RTCM Recommended Standards for Differential NAVSTAR GPS Service 2. 0" (RTCM paper 134-89/SC104-68). DMR (Digital Mobile Radio) Parameter Frequency range System Speed Modulation Receiver settings Input-Type(s) Additional Info Value VHF/UHF (136 ­ 147 / 403 ­ 470 MHz) Digital two-way data and voice system 4800 Baud 4-FSK with pulse shaping BW = 30 kHz IF Data or voice DMR (Digital Mobile Radio), also known as XiR in Asia is a two-channel TDMA system for the transmission of voice and short text data. The mode is used by government institutions, security, rescue or big firms for internal voice and short message communication. To use the mode set the Translation to the frequency of the IF output of the receiver. All Frames means besides data text and voice frames, every control frames will be displayed as well. At the same time the last voice session will be saved in a . wav file in the Data-Output directory. The display parameter Confidence shows the decoding quality, a value over 95% shows the decoding is very good, under 85% the decoding is not reliable. A small frequency error of the signal centre is compensated automatically. The parameter Carrier shows this centre after frequency error correction, the value should around the IF of the receiver. DTMF Parameter Frequency range System Modulation Receiver settings Input-Type(s) Value VHF/UHF Analog Selcal INDIRECT-FM FM, BW= 12 kHz AF, (IF) The entire call number is transmitted by consecutive tones in decade sequence. 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.
