[Elecraft] running computer connection while KXPA100 concurrently

[Walter Underwood]

I think pages 12 and 13 of the KXPA100 manual are pretty clear. That shows a cable from the KXPA100 to the PC at jack labeled “RS232 (PC)”.

This is the explanation from page 13.

"Personal Computer Interface Cable: All communications with both the KX3 transceiver and the
KXPA100 amplifier take place through this cable. This cable is not required, but provides enhanced
capability to operate the KXPA100 using the KXPA Utility program, for updating firmware in either
the KXPA100 or KX3 and other functions (see Utility Program, page 32 for details.) Also, this cable
provides communications between your PC and the KX3 through the KXPA100. You do not need to
connect the KX3 directly to your computer. Simply load the KX3 Utility program, be sure you have
the correct serial port selected, and your computer will find the KX3 as long as it is powered on.”

If I am therefore using the ACC1 port for the KXPA100.... I don't have the port available for the computer to see the KX3 info.. right? Therefore NaP3 has no rig or frequency info to use.
