1c0b746e5SOllivier RobertREADME file for directory ./clockstuff of the NTP Version 4 distribution 2c0b746e5SOllivier Robert 3c0b746e5SOllivier RobertThis directory contains the sources for utility programs designed to 4*2b15cb3dSCy Schubertsupport radio clocks. chutest.c is desgined to test the depredated 5*2b15cb3dSCy Schubertchu_clk line discipline or STREAMS module and can also test a CHU 6*2b15cb3dSCy Schubertmodem in raw mode. 7c0b746e5SOllivier Robert 8*2b15cb3dSCy SchubertYou can make things in here by typing one or more of: 9c0b746e5SOllivier Robert 10c0b746e5SOllivier Robert make propdelay (or `make') 11c0b746e5SOllivier Robert make chutest 12c0b746e5SOllivier Robert 13c0b746e5SOllivier RobertPropdelay computes high frequency propagation delays, given the 14c0b746e5SOllivier Robertlongitude and latitude of the transmitter and receiver. Use 15c0b746e5SOllivier Robertthis for WWV/H and CHU. Don't use it for WWVB (the computation 16c0b746e5SOllivier Robertis easier for that). 17c0b746e5SOllivier Robert 18c0b746e5SOllivier RobertChutest can be used to input and process data from a CHU modem 19c0b746e5SOllivier Robertattached to a serial port. It will use the CHU line discipline 20c0b746e5SOllivier Robert(if installed), or raw mode otherwise. This was used to test 21c0b746e5SOllivier Robertout the initial reduction algorithms, and may not be up to date. 22
