(1) Modified radar-PC console display such that it displays channels 2,4,6,8 every other time and 1,3,5,7 every other. (SHDATA.FOR). This is to be able to see also the even-numbered beams as easily as the odd-numbered ones from the console display. (2) The radio clock does not work. On the communication PC, a process was set up which writes the file /home/stare/data/curtime.dat every second with the current time. The comm. PC gets maintains its correct time by xntpd from han1.fmi.fi, which is bound to GPS clock. Thus whenever the radar-PC wants an accurate (up to 1 sec.) time it can read s:\curtime.dat. So, rcclock.c was modified such that it tries to read this file, and if it succeeds and if month,minute and second are within bounds, it uses this time instead of the radio clock time. (3) Calls to gettime, settim, setdat were added in strdrv.for just before looptime call. Since gettime will call rcclock.c, this effectively sets the radar-PC CPU clock to the GPS clock. (4) In routine looptime settim,setdat were called at 1100 UT. This was changed such that it is called every hour instead of just 1100. This is because in some places of the program, date() is called instead of gettime [e.g. in aaben.for, where the file name is generated]. Before this changes (3) and (4) we had the problem that the disk files were named 03260301.f98 etc., because the CPU clock was wrong by about 40 seconds. Now the CPU clock is set (a) every time the program starts, (b) every hour.
