Normally UHF means frequencies in the 300-1000 MHz range. S-band \nfrequencies for transmitting telemetry from the craft is logical since the Malindi station operated by the Italian Space Agency ASI \nprobably supports only S-band. C-band is the traditional Chinese TT&C frequency band. The use of shortwaves is interesting and it is \nobvious from pictures of the re-entry vehicle that shortwaves is used during the touchdown phase. Whether or not shortwaves is used on \norbit is unknown.\n\nThe only illustration that could possibly indicate that there are shortwave transmitters in orbit can be found on the PLA Daily headline \nbanner reprdoced below. The two whips at te bottoms of the service module couldpossibly be a real representation of antennas. \n\nIs anyone knows the exact frequencies they are using aboard on Shenzhou 7?\n\n\n\"-\"\n\n\nLuc Leblanc VE2DWE\nSkype VE2DWE\nwww.qsl.net/ve2dwe\nWAC BASIC CW PHONE SATELLITE\n\n \n\n", "attachments": [] }
