David,
I tuned in the ARRL code practice and bulletin and CW tone is very good. No pops or things along that line. However the AGC needs a bit of work. I did a comparison of Peaberry CW to HDSDR. Using the slow setting on both HDSDR and Peaberry CW, I found HDSDR keeps the audio at a more consistent level. The CW Peaberry wavers quite a bit at any level.
OK, I have to ask. Do your efforts with this new program pretty much kill the need for the firmware I have been working on?
