The latest version of FLdigi, 3.22.10, now has its own, cw audio bandpass filter,

to help filter out any qrq cw edge noises made in TRANSMIT MODE.

Even with 6 milliseconds of rise and fall time, at 75 wpm,

here is a spectrum analyzer picture of the edge noise that is still present:

I hope Synaptic Package Manager on Peppermint gets this update. Chuck, how can I install it now on Linux based operating system?
