Hi Don, Thanks again for your prompt reply. Not all laptops available today have a card slot. I am using the ACER 5724Z which does not have a card slot.
Referring to page 21 of the KPA owner's manual, I am using the KPA/K3 AUX Cable. If I want to upgrade the firmware on all three units (K3, P3, and KPA) then can you or Elecraft recommend a permanent configuration of serial cables that will enable such a requirement? It seems to me that if there is no answer to my last question then I will need to change the serial cable connections for each unit every time that I need to upgrade the firmware. The alternative is to take the advice of Fred Cady on page 247 of his excellent manual. Many thanks once again for your valuable help Don. 73 from Charles - M0BIN On 8 November 2011 20:07, Don Wilhelm <d...@w3fpr.com> wrote: > If you must operate with a laptop, may I suggest you look around (EBay for > example) for an older Inside Out 4 port Edgeport USB to serial adapter > (converter).
