6600/KPA-1500 Not Sharing Freq

My 6600 shares freq with Steppir controller very well. When I decided to add freq control to the KPA-1500 ,I ordered the CBL-FLEXKEY usb cable from Elecraft, followed all the instructions but the KPA-1500 not responding to band/freq changes from SDR 3. What is interesting is if you look at  the log on the USB cables under SDR3, the band changes are going out on those cables and are reflected in the logs but the 1500 not responsive. Have tried 9600bps and 38400bps, bypassing  the usb  hub I have plugged into 1500 usb, set the cable type as CAT, auto-report enabled,radio = serial, tech mode=on. Any thoughts/trouble shooting ideas?

Is there a way to look at the KPA-1500 log to see what is happening?

    Hi Roger

    This behaves the same way as any RS232 USB device being controlled by the radio.  The baud rate setting in the radio and the amplifier need to be the same value.   Can you post screen shots of your USB setting from SmartSDR?  

    You will see there is a logging function that shows data being sent to the amplifier based on your choice. which I recommend as Source:  TX Antenna and the antenna port you have the amplifier connected to.  

    Section 28 on the SmartSDR Software Users Guide discusses the RS232 settings.

    Your KPA1500 will also need to think it is connected to a Kenwood radio (or a Flex Radio if it has that setting).  Flex radios send the Kenwood CAT command set.

    You may want to give Elecraft a call and ask about setting up the KPA1500 with that cable.  I looked on their web site and was not able to find any documentation.
