Hi everyone,

I was just getting interested in buying a Datong FL-2 or Fl-3 notch filter, then the company decided to quit them. Anyone out there know where they are still sold (Universal and Grove not, that's for sure)? Or maybe a second hand one, that's alright too.

As an alternative I came up with the MFJ-752C, but what exactly is this: a DSP or normal analog audio filter. The MFJ web page just talks about "Two independently tunable filters let you peak, notch, low or high pass signals to eliminate heterodynes and interference" while the Universal web page talks about "5 tunable DSP filters, plus 10 programmable filters." Anyone using this thing and can shed some light on it? Would be grateful.

Greetings from Taiwan,
