[RTTY] Comments on "RigExpert"

[Jim McDonald]

It's interesting that the question was asked on the SteppIR reflector 
originally.

I've never used a RigExpert, but it seems to me that he compared it only to 
his one sound card and is assuming that his sound card is representative of 
all sound cards.  He also doesn't say what software he is using, which we 
know makes a significant difference.

I've seen many postings from him on the Icom PROIII reflector but never on 
the RTTY reflector and have never heard him on RTTY.

I don't have a PhD in engineering, as he adds to his signature line in all 
of his emails, I'm an accountant, but his testing methodology and 
qualifications in RTTY decoding are unknown.

Howdy
I took the liberty of forwarding the message below to you gentlemen for
comment. I have used almost everything HAL ever built along with AEA,
soundblaster, Rigblaster and others but have never used a RigExpert and was
wondering if some of you might comment.

Howard claims below that it copies 100% when sound card devices are copying
nothing really got my attention!

Any of you done a heads up comparison?

Thanks, Ed W4EP
