Greetings;
I'm new to the K2; just got SN 2676 10w CW only,  with firmware 2.04P 1.09. I put in the audio filter option. 

I wonder.... how excited should I be to do some mods like the CW waveform mod, the BFO mod, and the PLL temp compensated mod. Things like this that really just get it current. Will this really enhance the rig? All things equal, these are inexpensive things so I'll likely order them Monday anyway, but does anyone have thoughts on whether or not I'll notice a change? 

Thanks;

PS - I did notice a kind of soft click or pop when keying sometimes - is this what the related mod addresses?
