Hi, Well I've always found that the K3 internal speaker is pretty lousy on CW, OK with SSB. Not a big problem 'cos I always use phones for CW. I remember reading a few years ago about some experiments with enclosing the rear of the speaker to improve the sound. I've done all the factory RX audio mods on #345.
Something else I've noticed is the huge variability of the tonal quality of CW on the bands. It's certainly not a receiver fault 'cos checking the same signal with the K2 it sounds the same. Two totally different receive processing architectures. Finally, word in the bazaars is that LoTW has blown up with loss of data and corrupted backups. I hope not!
