Re: [Flexradio] USB Adapter Disabling itself for no apparent reason?
I've found this problem with USB connections. I simply unplug the device and plug it back in then it usually connects. I'll look in to it, I do not know how to make it more persistant at this time.

Hi Tim, Gerald and all, That is good advice, but don't forget to check the USB connection on the set-up window. However, it is irritating that all the small switching transients coming from the mains power circuits trigger the USB adapter off. There is no better help but good grounding of your house mains power system, and even better in your hamshack for your computer, all peripherial equipment, the radio itself, of course, and finally the RF-ground. How to lay out all the grounding cables and points and draw the signal cables to avoid grounding loops, that is more art than science. Every location is different, I simply can't give any suggestions. If you cannot eliminate the transient, you still can suppress its influence to the sensitive USB circuits. The apparent reason of your problem is the common mode transient current that somehow got coupled to your USB cable. You can reduce the coupled current (and the interference) by increasing the common mode impedance of the cable. Use ferrite chokes at both ends of the cable. I use four turns of cable around the center pole of a double E-core made of grade N27 ferrite. http://kotisivu.dnainternet.net/ahti/sdr-1000/usbferrite.jpg Good luck and 73, Ahti OH2RZ ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com ___ FlexRadio mailing list FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archive Link: http://www.mail-archive.com/flexradio%40flex-radio.biz/ FlexRadio Homepage: http://www.flex-radio.com
