Rich,
Not quite. You do NOT want to connect the CBLP3Y cable to a USB to serial port adapter. You will not only have communications failures, but you may damage the K3 USB port output and the USB to serial adapter because you will have two drivers on the same RS-232 signal lines. I assume you have a P3 since you have the CBLP3Y cable. You can connect a simple RD-232 Y cable to the PC port on the P3 with the CBLP3Y cable plugged into one side of the Y and the serial cable to your SDR receiver on the other side. Your SDR receiver must turn its driver off - it can listen to the RS-232 traffic, but it cannot transmit requests or commands. You may have to set up virtual ports with LP-Bridge or Com0Com. 73, Don W3FPR On 10/11/2018 11:31 PM, Rich wrote: > If I am reading correctly in Fred's book.

Thank you. I thought I found a way to use the USB port for audio/rig
control and the other for sending Freq data to the SDR. I guess not. Thanks again Rich On 10/12/2018 11:12 AM, Don Wilhelm wrote: > Rich, > > Not quite.

Rich,
The RS-232 lines in the K3 are essentially the same as the lines to the internal USB adapter. That means that they are NOT two separate ports. Yes, using the serial dongle that comes with the K3S or the KIO3B upgrade for the K3 does allow you to use an RS-232 port or USB adapter to connect to the K3, but you must move the switch on the back of the KIO3B in order to do that. You would have to link the two com ports using a computer application, and I don't know of one that will do that. i.e. take the COM port data from the K3 USB 'COM' port and feed it to the port that connects to the SDR. As I recall, LP-bridge may have that capability, but it rather complex and I have not studied it. 73, Don W3FPR On 10/13/2018 9:04 AM, Rich wrote: > Thank you.
