Hello, Got a Pigtail Interface for using the KX3 on my iPad. The KX3 needs to be interfaced to the Pigtail with an RS232 (DP-9) Serial Cable. I do have the KXUSB.. Is it possible to use a USB to Serial Interface for that one ?? Or rather design a new cable with a DP9 (2; 3; and 5) ?? Mni tnx. 73! Helmut, OE1MHL
