Phil,

RF wise, it should be the same as the K3.
Computer-wise, it all depends on the computer and the equipment between the computer and the K3S. Unfortunately "Universal Serial Bus" is not so 'universal' when applied to the user. With the variety of computer and other gear between the K3S and the computer, the number of questions seem to expand exponentially as the list of devices and applications expand. USB offers a new set of "challenges" that are not present with RS-232, and the unfortunate answer is that it is computer dependent. Not a good situation for Elecraft support, but it is reality. USB is not as "universal" as the originators would have hoped it to be - it does have OS and device dependencies.

Yes, the K3S USB connection should behave much the same as a K3 with a USB to serial adapter. The K3 simply moves the adapter inside the K3S, but the FTDI driver does have its limitations. In the computer world, things are OS dependent, Browser dependent, Com port assignment dependent, and a host of other dependencies. Since the K3S has entered the world of USB dependencies the OS and the K3S relationship tightens. No longer do we have to simply determine which "USB" Com port is connected to the K3S, but we must be able to dig down onto the chaos of USB port assignment that is being used by the particular OS you are running on your computer.

IMHO, RS-232 interface is much more straightforward, and more usable by those who are not "computer geeks".
