  • Mac OS 8.x or Mac OS 9.x


Questions & answers

Q: Does BeamFinder require one of this turbo-powered Macintosh computers? I am using a rather old Macintosh model in my ham shack and wish to use BeamFinder on this computer.
A: There is no need for a modern G3, G4 or G5 model. I am operating BeamFinder even on a PowerMac 7600 with 132 MHz only - and it works, not that fast but good enoug in practical applications, I think. BeamFinder is hungry for memory though, i.e. make sure your ancient computer has at least 128 MB RAM available or even more. I prefer using BeamFinder on my good old 500 MHz G3 PowerBook (Pismo) and it works very fine.
Q: I noticed that you are currently working on an OS X version of BeamFinder. I guess a high-powered machine is then required to run BeamFinder, right?
A: This question is difficult to answer because the OS X version of BeamFinder isn't yet available. I would say: if you are happy with OS X's performance on your computer, you will be happy with BeamFinder's performance too.
Q: Can I operate the current BeamFinder version in OS X's classic mode?
A: Sure, this is what I do and BeamFinder cooperates with OS X's classic mode very nicely.
Q: I'm unclear how your software gets it's data to plot. Do I manually key-in QSO information or does it harvest data from DX cluster via Internet or via radio frequencies?
A: Some functions may be launched by a simple mouseclick in the pulldown menu (for example, when calculating features exclusively relevant to your home location), others require data in dialog boxes or, alternatively, by typing data in the Command Editor's editfield. However, all data may be loaded from ASCII files, i.e. you may queue all grid locators, functions and commands in a text file which BeamFinder uploads on request. Thus, the software does not harvest any information from dx clusters or any other resource in the internet directly, this requires a translator program that reads the internet data and generates a BeamFinder-compatible ASCII file. I will perhaps address this type of applications in future releases of BeamFinder.
Q: I unfortunately do not have a Macintosh computer because I am using Windows. Is there a Win-version available or do you plan to implement a Wintel version of BeamFinder?
A: I gave up programming this type of computers and, as far as I can see, I will never return to it.
Q: What about Linux?
A: Hmmm ... sounds interesting - but I am currrently not prepared to launch a Linux version of BeamFinder.
