RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

My Hobby Website:
Thanks to a tip provided by Mr. Ted Bruce, an RF Cafe visitor, there is now a known means of capturing and printing any screen displayed by RF Workbench. Using a free program named “DOSBox,” users can easily capture any screen display and paste it into any Windows program – Word, Excel, Power Point, etc. - for printing. Instructions are given below for how to download, install, and use DOSBox. DOSBox will replace the DOS window that RF Workbench normally runs within, so the use interface remains the same.
NOTE: I have verified that RF Workbench will run in DOSBox on a 64-bit Windows 8.1 OS. Be sure to use the number keys above the letter and not the numeric keypad!
Please click here for the RF Workbench homepage.
Go to the following website and click on the appropriate version for download (probably the Windows option). Save the file to your preferred location. Be sure to read my instructions.
I do not provide any support beyond this page. Please do not write asking for help.
In order to eliminate possible difficulties with the old DOS 8-character file name, I recommend creating a folder named “RFWB40” right off the root c: drive directory. Wherever your copy of RF Workbench resides now, just make a copy of it and paste it into the root C:/ folder. Rename the folder to “RFWB40” in order to eliminate spaces in the file name.
Everything seems to run better if you switch the resolution of your video card to 800x600 pixels, and use something less that than 24-bit color mode prior to performing any of the other steps that follow. If you have a super fast computer, it probably will not matter.
Open the Windows Explorer program and navigate to the folder where the DOSBox program is saved, and run the “dosbox.exe” file.
You will get a window similar to the one below. Enter the following command shown to mount the c: drive.
mount c c:\rfwb40 (Enter)
Then enter the following command to log onto the new c: drive
This maximum will vary from computer to computer, there is no standard.” This is definitely an experimentally determined setting, but I get pretty good performance in the default mode. Probably the faster your computer is, the less you have to worry about it.
Finally, type in the following to launch RF Workbench:
