A new generation of high-efficiency coarse and medium-fine crushers: CI5X series impact crushers
·PACTOR 4 is an adaptive transmission mode that provides higher throughput and improved robustness compared to PACTOR I II and III Ten so called Speed Levels SL are specified which are predefined combinations of modulation type DBPSK DSSS DBPSK DSSS DQPSK BPSK QPSK PSK 8 QAM 16 QAM 32 and channel coding 1/3 1/2 5/6
·Pactor modems by SCS tend to use 1400/1600 Hz tone pairs as the initial Pactor 1 tones On USB the dial frequency will be KHz below the centre frequency of operation It is common practice to refer to the centre frequency for example on 20m a common frequency used is CF which is likely to be USB dial frequency

·PACTOR 4 with its 10 speed levels and adaptive equalizer adjusts itself ideally to varying channel conditions and guarantees reliable data transfer even under very poor propagation conditions Due to this high reliability P4dragon modems allow transmission of safety relevant data via shortwave and provide an excellent value for money when
·PACTOR operates adaptively so the baud rate can be either 100 or 200 Baud During day time 200 Baud may be successfully used In the evening however strong propagation distortion occurs which necessitates a reduction of the baud rate to 100 Bd PACTOR includes HUFFMAN data compression by design
·With PACTOR II a modern narrow band and reliable two channel PSK mode is available which covers the needs of both amateur and professional users for a secure and fast data transmission system The good performance during disturbances and a small bandwidth of 500Hz are achieved by the use of a two channel DPSK modulation

·remote locations PACTOR II is backward compatible w/ regular PACTOR Often used nowadays for WinLink 2000 • Disadvantages Normally requires TNC or PCKTERM software for soundcard use $ PACTOR II used to cost a lot of money required specific type of TNC Not suited for daily live communications PACTOR Trace
PACTOR has founded in 2010 and it is with much pride that already counts with some of the national tops in its publication areas
·This change opens up the ability to use PACTOR 4 protocols for higher speed data transmission on Amateur radio bands Something Marine bands already supported Previously the symbol/baud rate rule limited speeds on Amateur bands to PACTOR 3 PACTOR 4 is roughly 2X the speed and PACTOR 4 modems also have better performance with noisy

Ein Pactor Modem funktioniert indem es Daten in ein spezielles Format konvertiert das über Funkwellen gesendet und von einem anderen Pactor Modem empfangen werden kann Es verwendet einen proprietären Übertragungsstandard um sicherzustellen dass die Daten sicher und zuverlässig übertragen werden

·The PACTOR 2/3/4 signal must always go the indirect way which is using the SSB modulator to generate the HF signal This is of no disadvantage providing the transceiver is not overdriven Some useful hints to properly setup the transceiver • For PACTOR 3/4 use a kHz wide IF filter usually also used for SSB/voice Do not use a smaller
Als kompromisslose Weiterentwicklung des PTC II wurde der DR 7800 auf das neue Highend Übertragungsverfahren Pactor 4 und dessen unübertroffene robuste und schnelle Datenübertragung auf Kurzwelle zugeschnitten Fühlen Sie sich wie zu Hause wenn Sie ihre E Mails von jedem Punkt der Erde über Kurzwelle versenden Um Ihnen den Einstieg zu
·The fixed frequency offset is used in automatic scanning mode In PACTOR fixed offset has 200 Hz as a default value FFT The FFT button opens and closes the power spectrum window You can for example close the power spectrum window when the decoder has locked into correct frequency in order to get more space for text window
·PACTOR is a frequent visitor in the amateur radio bands In addition commercial users also use this system The data protocol was modified into several variants for this purpose During day time 200 Baud may be successfully used In the evening however strong propagation distortion occurs which necessitates a reduction of the baud rate
