Re: [Elecraft] [K3] K3 and Firewire

Hi,

I agree with you, Brendan, Ethernet is the way to go. Ethernet is always
transformer coupled so there are no problems with ground loops and that also
helps with noise, although the unshielded Ethernet cables don't help in this
regard. More and more microcontrollers, especially ARM based ones, now come
with fast Ethernet controllers onboard and IP stacks are easy to come by
these days. So a separate embedded computer to run the Ethernet interface is
often no longer necessary.

 Forget Firewire for this. Firewire is admittedly very good but it's far
 from standard on non-apple products and USB3 is going to give it a good
 run for it's money in all areas except perhaps Pro A/V where latency is
 a huge concern. 
 
 However the real issue with both firewire and USB is the need it then
 creates for the Vendor (elecraft in this case) to maintain drivers for

Hey Paul,

This is a great topic.  Sony, Apple, and a few other companies have been
using the Standard IEEE 1394 Interface,  commonly known as FireWire for
a number of years.  It does have many benefits.  From my limited knowledge
as I am not an EE,  the protocol seems to be an extremely efficient way of
connecting our endless devices.

I do use this protocol a lot.

 Firewire can do a lot of things that USB and serial communications never
 will.
 
 It's faster with video and disk I/O because the protocol is leaner, 
 and you can create networks with it.
 
 I think that a FireWire network between a rig like the K3 and a 
 computer would be the perfect interface because every piece of 
 software can have its own dedicated connection to the radio, 
 something difficult to implement with a serial connection.
 
 Firewire will also stay around because it's used as the Fly-by-wire 
 bus for the F-22 Raptor.
 
 Any thoughts?
