Hello Yaesu Fans: You may be interested in the new DSP module from BHI in the UK. I recently received this unit and have written a short review of the performance improvement with a modified Mark V. I have posted the review on my W2AJI webpage here: http://home.earthlink.net/~cherokeehillfarm/id2.html 73 and Happy DXing, Mike W2AJI
