I've used the "hyper sensitive" profile for the last few years and it seems to have always worked very well. But I've rarely seen this profile mentioned until I noticed it in Dave's Excel spreadsheet

In that case did any one use the AA6YQ FIR512 profile or the Dual Peal Filter in MMTTY for the CQ WW RTTY? What did you think about it? I did 15m single-band and used the AA6YQ FIR12 profile for the
