Hi Alan, This note is on page 9 of the KPA500 manual. Two way control only occurs with a K3.
"Band switching control in which the KPA500 follows the transceiver band selection without transmitting is available with other popular transceivers such as Icom and Yaesu with the appropriate interconnection cable. See AUX Connector Interface on pg 17. However, the control is one-way. The KPA500 cannot command the transceiver to change bands." 73, Mike K2MK WA6KEK wrote > > I made up a cable to go from my FT-2000 Band Data port to the Aux port of > the KPA500.
