[Elecraft] [K3] Suggestions/Considerations speaking of digimodes functionality

[ik1bxn]

Hi Joe, maybe translating from italian into english I did not explained in
clear way what I mean, I'll try to clarify.
Usb : I'm not suggesting to integrate a conventional 232/Usb converter
inside k3 (even if it would be possible to do by cabling all the firmware
necessary to have everything onboard without OS driver need)  but
re-engineer the internal I/O in order to make available a standard Usb port.
For what I know, Usb is totally non related to any COM port. If you plug
into your pc an external Usb device (webcam,hard disk,audio card etc) can
you see any relation to a COM port ? I think you can't see. The pc  will see
some Usb device and will use it according to its Usb interfacing subsystem.
Of course it's a cost I know, but even if rs232 will live for many years to
come (because it's an industrial reliable standard), at home we have always
Usb and seldom rs232 port. In addition (my opinion of course) having Usb
interface  should be useful to give to k3 the look of a modern rig (even if
we know it's a modern rig).....not an old fashion rig as extremely often I
read surfing the internet....comments coming from people that evaluate a rig
looking if it has a TV set inside, lot of displays many leds and so on. I
think it should pay. Better would be having also an Ethernet interface !

Signalink : I spoke of that because I have it, but it's a much more general
matter, anyway Signalink it's not only an additional Vox, it's a complete
(and optimized for our HAM purposes) sound card that interfaces with pc via
Usb. In addition it takes care of PTT by using a Vox circuit. At Signalink
there are regulation for IN and OUT level and PTT delay. Using this
interface the pc internal audio card is completely out of game, so you can
play a DVD, listen system sound and so on when you are in PSK. Last, as 
Signalink provide a total galvanic separation and in addition it converts AF
levels into digital data and releases them to pc via Usb...this let you much
more free from any possible RF interference.
