In addition to Don's suggestion, I have found this USB-Serial-K2 line to be very RF sensitive. Make sure this line is not run over/near your coax. I also use snap-over RF beads to choke any RF, or at least minimize, the RF on this line.
I experienced similar symptoms. My problems were minimized with the above precautions. GL, Guy N7UN >I see you are using a laptop, and I presume you have a USB to serial >adapter that you are using.
