I am having problems trying to use the TLW program from the ARRL
antenna Book. The version is 3.0.

Current version is 3.0b:
http://www2.arrl.org/notes/9043/index.html


On one machine when I select the "Tuner" button the program does not
come up. It does show an instance as a sub task of the TLW on the task
bar at the bottom of my display. Clicking the subtask causes it to
blink but nothing else. In the Windows Task Manager it shows as a
process momentarily and then disappears.

That sounds like a broken shortcut or that you're running the MSDOS
version (TLA.exe) from a Windoze shortcut. Try:
Start - Programs - ARRL Antenna Book - TLW
instead of using the shortcut on the desktop.

On the other machine the tuner window comes up but the on choice that
will display is the T-Network. I am certain this one worked well a
short while back.

Sounds like the program is corrupted. Uninstall, reboot, and
reinstall.

1-make TLW work in my environment.

Get someone there who knows computahs. Have them run a virus scan,
spyware scan, scandisk, registry check, Windoze updates, and other
maintenance tasks.

Norton keeps the virii & spy ware in check, the updates are current. I
have not run scandisk in a while so I will get that on the schedule.
As far as the registry is concerned I will save that as a last resort
because of the risks involved.

2-do the calculations manually (rather not, I am both old & lazy)
Chapter 25 latest ARRL Antenna Handbook.

What calculations?
The equations that provide the basis for the calculations in the TLW
program.


3-G4FGQ programs (good possibility)
4-Find other affordable software for the task.

What task? If you want help finding alternatives, it's a good idea to
describe what you're trying to accomplish, and what you have to work
with.
I thought I was doing that. The services performed by the TLW program
are what I seek. I made the assumption that those interested in
helping would already be acquainted with the program.

You have pointed out the likely trouble spots and I will check these
first! I also have more information in that I have discovered that the
TLW program is working properly on my backup system. I suspect that
wherever TLW stores its session to session parameters has been
corrupted with un computable data. I have run many absurd
configurations while testing design limitations.

You asked the right questions to get me on track.

I prowled around the registry without anything looking interesting.
Upon examining the folder containing the tlw3.exe file I found a file
"TL.DEF" which I replaced from with the one from the working backup
machine and all is well!
I will now return to my matching studies...

Thanks for the help,
