[Elecraft] [K3] LPF DSP modification

[Joe Planisky]

Hi James,

I used an Exacto knife to cut the traces on mine.  They're pretty thin  
lines, so it doesn't take much to cut through them.

Do note that the LPF mod does NOT give you the extended low frequency  
response on TX and RX that you would get with the board exchange.  If  
that's not important to you, then the DIY option is a good way to go.

Someone recently mentioned that Elecraft offered to modify his DSP  
board if he sent it in and that the turn-around time was just a few  
days.  Don't know if that's something they're generally offering or if  
it was a one-time-only deal for him.  The downside is you're without  
your K3 for the time it takes to get the modified board back to you.
