Great to hear from you Pedro! Your pass prediction sites are quite popular in our region. We have been routinely using it to work satellites by manual Doppler correction. Your page on expected satellite decay is also being followed by many of us.
On a side note, is it possible to convert it from http to https? Many antivirus softwares and even Windows 11 blocks http sites by warning them as 'Untrustworthy', though we very well know that they are safe. Several new users moved away from the site because of this warning. In fact, the same problem is there for many of the ham radio related sites which have been there for a long time.
