[Elecraft] P3, what lies ahead?

[David Gilbert]

Doing it via a sound card would be counterproductive, but I fail to see 
how bringing them out digitally would require that much additional cost 
or complexity.  We're talking bits of data here, and there are other ham 
radio products (including SDR receivers like the QS1R and SDR-IQ) with 
USB interfaces.

But in case I am wrong on that score (entirely possible), why couldn't 
it have been made available as an option at additional cost?  Space 
isn't an issue, either internally or on the back panel.  I simply don't 
understand the reason for the omission, and I'm betting that this 
message thread doesn't lead to an answer either.

73,

Without a bunch of additional interface electronics, they're not compatible with a sound card input, so it's easy to understand why Elecraft didn't do that.  I suppose they could be brought out on a USB, but that would also add complexity and cost.  Both could be done, but Elecraft has to set realistic priorities.

In addition, new features can be added in response to user feedback, and we've seen plenty of examples of that.
