"And as far as ADSP² is concerned, this is just sensational -- absolutely sensational -- for emergency communications (my major focus) and difficult operating conditions so for me the price for that feature is a bargain. I urge you to listen to their web site simulation if you haven't already.  It is going to save lives." - Unidentified Customer

"Best product I have ever purchased. How do you do it??? DSP in a box - fantastic!" - David Leonard VK3KDL

"Fantastic! I'm going to order another!! - Great on CW!" "Fantastic product for CW. This is my third purchase of ADSP²! Use in mobile and fixed ops: - well done! - Roy Shlemon K6GVG

"The ADSP2 is a real marvel at reducing atmospheric noise and interfering signals. I am now able to copy weak signals that can not be understood without DSP. The low cost of ADSP2 coupled with its effectiveness is an amazing achievement in engineering."
- Roy Fisher

"You folks got this DSP right! Best I've used to date." - Terry Fitzwater

"As the QST review said, the noise reduction IS impressive and the notch filter IS dramatic. Very FB." - Alan Denison W4OFV

"Just tuning around with this and testing it out, it is unbelievable how well this works.  On 40m and 80m (at home) with background noise at S8-9 you might hear a station in the muddle.  Press once and the signal pops out of the mud and is intelligible.  Press again and most times it's like talking on the phone!  Totally phenomenal.  Now I can't decide to put it on the boat, in the car or at home."
