I have always suspected that there is some other factor besides the chipset that can make the difference between success and failure with a USB adapter. Perhaps the chipset of the USB controller, or what other devices are connected to and using the same USB hub as the serial adapter.
You would not think that anything so essentially simple as low speed (by current standards) serial communications could cause so many headaches. However last night I downloaded W6CQZ's new JT65-HF software and spent about two hours trying to get it to key my K3 to transmit, before discovering it would only work when connected to a real serial port. Not the virtual serial port emulator and not LP-Bridge either. I know that isn't the same as a USB adapter, except that is also a virtual serial port. It seems that anything that is not a real serial port can throw a spanner in the works if Murphy has a mind to. Partly as a result of sluggishness running the JT65 software, I ordered today a new PC for the shack. And since it doesn't come with an RS-232 port I ordered at the same time a two-port PCI RS-232 card. It cost just over £20 and I will now be able control two separate radios without needing to resort to any of these troublesome USB adapters. (I also made sure the PC I ordered came with a Windows XP "downgrade". I *know* everything I want to use works under XP, but I've seen plenty of reports of problems with Vista and 7. This won't be an option for much longer - another reason for getting a new PC now rather than later.) ----- Julian, G4ILO.
