Compilation notes to produce the IOWA Hills application

[GW8RDI]

Sorry if this is wrongly posted, but I would appreciate any pointers to how to compile the IOWA Hills application.
I've download the IOWA backup from the indicated page, and found that the IOWA Hills IIR Filters application shows the frequency entered (69452000 - 69.45 MHz) divided by 10 along the X-axis. Wondering if that's just a display issue, or if entered freq. needs to be multiplied by 10. Any advice would be appreciated.
Many thanks, Rob

i've added compilation notes for the dsp library - NOT the application!
i don't think the source of the application is freely available, right?

frequency divided by 10 on X-axis: no idea!

Probably not, I could see it, hence my asking. The link to the archive of the web worked for the app exe at least.
It's a shame that the work done on the app is going to be lost, seems like its still a useful application for many people.
Is there anything better out there that's freeware?

Don't know of ready to use gui applications.
You might try or look for "ready to use" scripts in octave and or python with numpy, scipy and some plot libraries ..
Please be so kind to report your findings.
