"There is an experimental subprogram included with OH5IY's MSSOFT 4.3, versions 3 on up, that can help you visualize which directions should be favored at any particular hour of the day during a shower. This program, which is mentioned in the documentation, requires that you create a simple ASCII text file which includes grids in a circle around you at some reasonable distance, such as 1300 kM. While it takes some time to do this, the resulting display may help you better understand how meteor trails favor particular paths. An example grid-listing is included with the program for OH5IY's home in southern Finland; you can either edit that file by replacing his listed grids with your own list, or create your own file. The program is called RMSH; when you invoke MSSOFT normally, a batch file called MS.BAT calls up CMSH. In this case, you can copy the MS.BAT file and rename it to, for example, MSR.BAT, to invoke RMSH. To modify the original MS.BAT file, simply change the CMSH listing he CMSH listing to RMSH instead. To create your own grid list for use with RMSH, the following may be helpful: 1. Using a grid-distance program, such as N4AZI's "Grid Locator" or any other, find grids that lie a particular distance from your home, such as 1300 kM. To start with, find eight grids spaced out every 45 degrees around the compass. 2. Mark those eight grids on a grid map, and roughly trace a circle through them such that the circle represents a radius of grids that are all about the same distance from your own QTH; for example, 1300 kM. You do not need to be very precise; +/- 100 or even 200 kM is probably more than good enough for RMSH to at least show you what you might expect. 3. Write a list starting with the northernmost grid and going clockwise around the circle back to the first grid. You must limit the list to no more than 63 grids. 4. Either edit OH5IY's original list for his QTH, or create your own file, with the list of grids, in the same format as Ilkka's original file. You can rename his original file under another name; for example, OH5IY.LST or whatever. Your list must now be named the same as his original list. Then you are ready: type MSR.BAT (assuming you created that new batch file to call RMSH instead of CMSH). The usual opening screen, with slight modifications, will appear; type G for gradient, and ...... wait..... and...... wait..... and.... wait. Yes, the program is runningYes, the program is running; you can see it calculating, using the list of grids you created. My 486DX33 requires roughly a minute to calculate through the entire list of grids. If you have only a 386, you may want to reduce the total number of listed grids to, say, 24 or 36. Eventually, the calculations will be completed and RMSH will display a heading map. You can then hit your SPACEBAR to advance the program in 1/2 hour increments to see how, as the shower radiant changes origin with respect to your own QTH, the favored paths shift around the compass. Be careful that you do not exit the program before you want or you will have to wait for it to recalculate again! Ilkka cautions that, in his opinion, this program is of dubious value simply because it is the result of a wild-eyed idea that he had (my own interpretation of how he conceived the idea!) and its accuracy and thus value and utility are as yet unproven. Perhaps some of you who made numerous QSOs throughout the shower can coordinate your QSOs and observations against the program's predictions? Enjoy, Steve Ko0U/1"
