1abb0f93cSkardelREADME file for directory ./clockstuff of the NTP Version 4 distribution 2abb0f93cSkardel 3abb0f93cSkardelThis directory contains the sources for utility programs designed to 4*8585484eSchristossupport radio clocks. chutest.c is desgined to test the depredated 5*8585484eSchristoschu_clk line discipline or STREAMS module and can also test a CHU 6*8585484eSchristosmodem in raw mode. 7abb0f93cSkardel 8*8585484eSchristosYou can make things in here by typing one or more of: 9abb0f93cSkardel 10abb0f93cSkardel make propdelay (or `make') 11abb0f93cSkardel make chutest 12abb0f93cSkardel 13abb0f93cSkardelPropdelay computes high frequency propagation delays, given the 14abb0f93cSkardellongitude and latitude of the transmitter and receiver. Use 15abb0f93cSkardelthis for WWV/H and CHU. Don't use it for WWVB (the computation 16abb0f93cSkardelis easier for that). 17abb0f93cSkardel 18abb0f93cSkardelChutest can be used to input and process data from a CHU modem 19abb0f93cSkardelattached to a serial port. It will use the CHU line discipline 20abb0f93cSkardel(if installed), or raw mode otherwise. This was used to test 21abb0f93cSkardelout the initial reduction algorithms, and may not be up to date. 22
