I'll chime in here with the fact that I had problems with a couple of USB-serial cable since I am running Win7/X64. I went to www.usbgear.com and found one for $12 that came with Win7/x64 drivers. Seems to be working just fine. Plus, when I sent their tech support a question I had the answer within 1/2 a day.

It all depends on OS, proper driver for that OS and possible conflicts with other devices/programs which create virtual serial ports. If you want to try an inexpensive adapter with FTDI chipset, look at byterunner.com. They have a number of choices, and list the chipset brand for each one. 73, Larry N8LP Dave, Thanks for your comments and suggestions but I should not need to change the com port number. I have been scanning the Internet and finding that there is no lack of problems with the prolific drivers and I am thinking I might just go buy some other interface. I am willing to go out and buy another serial/USB interface cable if someone suggests one that will work both with the K3 Utility as well as HRD (I do not need this to run simultaneously though). 73, phil, K7PEH -- View this message in context: http://n2.nabble.com/K3-K3-USB-Serial-Drivers-and-HRD-Connection-tp4706847p4 706984.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
