When you consider that the K2's buttons have two and sometimes three different functions already (there's a clock in there? Really?) I would prefer to have an outboard audio filter like the AF-1. Plus you need a knob or two and I don't think it would be very easy to retrofit extra knob functions into the existing radio.
I'd like one too, but I don't think it's practical in the K2. Maybe in the K2.1! 8-) 73, Ken Alexander VE3HLS --- On Mon, 11/29/10, jeff martin <[email protected]> wrote: > From: jeff martin <[email protected]> > Subject: Re: [Elecraft] K2 APF implementation? > To: [email protected], "Ron D'Eau Claire" <[email protected]> > Date: Monday, November 29, 2010, 8:47 AM > Ron, > Great idea!
