Dan, I cannot speak for Elecraft, but I suspect I know the answer.
In my opinion, the issue is frequency stability; the narrower the bandwidth the more frequency stability is required.
Frequency stability is frequently accomplished with a crystal oven, to keep the oscillator spot on. Heat eats power, so it may not be a compatible design objective for a QRP rig.
just my thoughts on it... 73 de Dave, W5SV On 5/24/16 10:27, Dan - VA3MA wrote:
Could Elecraft explain why the KX2 design doesn't allow operating say JT65 out of the box? What prohibits manufacturing the rig to do the narrow digital modes? Would be helpful to know Thanks Dan VA3MA I notice Wayne is ignoring explaining their design decision - commenting on all other questions ! ______________________________________________________________
