[Elecraft] K3: LPF, bass audio, new DSP board: Stirring the pot?

[Geoffrey Downs]

Regarding the new DSP board, I was not one of those who had issues with the 
old one or considered the K3 to be noisy on rx and I ordered the new one 
simply to keep my K3 #266 up to date. I use SSB almost exclusively, these 
days seeking dx on 80m with a headset.

Having installed the new board a few days ago my subjective and 
non-technical assessment so far is a more pleasing sound in the headphones 
with increased bass response and reduced white noise without loss of 
sensitivity. On tx slightly fuller audio from my HC4 with more mid range. 
(Both rx and tx assessed with equaliser all zeros.) So on the whole I regard 
the new board as an improvement. Worth the money? Well that depends on how 
you look at it and different people may have different views. I managed to 
convince myself that I could afford it and I feel no sense of disappointment 
after the event.

73 and Happy 2010 to all
