Can someone develop a K2 mod to give us (switchable) control of the CW quality - I like the rich variety of signals on these recordings. The bands these days sound a bit too perfect with all the T9X signals around! I suppose moving a large PSU near the K2 should give the AC modulation, how do we het the bullfrog on acid effect? It's much easier to copy a rough, chirpy signal in the QRM because it stands out from the norm. Some of the fists on the recordings were "interesting" too! I've just recalibrated my K2 filters to give me a widest CW filter at 1.5KHz so I can re-create the "wide open - hear everything" feel! It's HF CW field day in Europe and sitting on 20m (albeit not in great shape propagation wise) with a wide filter is great fun...
