[Elecraft] CAL FIL & Spectrogram?

[Fred (FL)]

I can't find any search references to "Spectrogram"
or how to download it on Elecraft mail BB?

I guess $50 is a bit much for this retiree to
invest for a sound program ...... 

Looks like all knowledge on BB of Spectrogram,
has been sanitized?

I thought there was a freeware version?

Thanks,
