Yes this site is still here!

Thanks to all those that contribute by sending me scans of manuals or photos. I've started adding review articles as I find them, I was interested to find an article by Dr Tong himself outlining the principles behind the FL1. Still a great filter 40 years later despite all the advances in SDR and DSP technology.
