RF DESIGN MAGAZINE SOFTWARE--> COIL.EXE

[Dale Parfitt]

Some years ago RF Design offered some programs on a 3.5" floppy. One of
these was COIL.EXE. Of all the solenoid coil programs I have had- this
was the easiest, most useful and dead accurate. Unfortunately the
machine it was installed on died.
Anyone have a copy of this program and could send it- must have been
quite small- perhaps 50K or less.

Thanks,

Go here for all of the RFD programs.

Good luck.

Yeah but you have to know the date to retrieve the right one. There are
many, and there seems to be no description.

Any suggestions? Is there an index?

Dale, you might like to look at this URL. It seems quite useful
http://www.geocities.com/homemade1234/coil.zip
but I don't think its the program you were looking for.

The very first page I hit on a Google search had a pointer to the program.

A google search on '"rf design" coil.exe' brought one hit, a site that
shows the following URL: http://www.alkeng.com/dload/coil.exe. I entered
this URL in my browser and was prompted for where I would like coil.exe
to be downloaded to on my machine. The downloaded file is 85 kB.

Roy's link was for the correct program- thanks to all who replied.

Hi Dale,

That's the one I've used, too. Recently I've needed some coils I
could wind quite accurately, and I discovered an error in that
program! The coil length, calculated from number of turns and pitch,
was in error by one turn. So I went looking to see if
http://64.130.134.245/saratogasoftware/ had a corrected version.
Well, there was a new version, windows-ized and with a lot more
machine screws for standard formers, but the error persisted. I
emailed John (John Mezak, K2RDX, who wrote the prog.) about it, and he
promptly corrected the mistake. The program now gives results even
closer to what I measure with careful measurements on HP/Agilent
equipment and in other ways for a few samples I tried. I highly
recommend it. However, I feel obligated to point out that the program
is now shareware.

If you want to avoid shareware, I find that PCAIRL gives very accurate
results, too, though I don't like the way that results are presented
quite as well. You may actually like the user interface better; it
depends on how you like to go about winding coils. You can find it
free at http://www.alkeng.com/.

Of course, Reg Edwards also has a coil program on his site. I didn't
find its results to agree with my measurements quite as well as the
two above, and still like K2RDX's program the best for accuracy and
convenience with respect to the way I actually construct coils. There
was also yet another one mentioned here just a couple days ago. Both
it and Reg's are in metric measure, and the other two I mentioned
above are "English" (American).

Cheers,
Tom
