I experimented a problem during WAE contest this weekend. I was working OK till this afternoon. When I transmit, N1MM freeze, and I need to rebbot my computer.
I tried many things, change USB port of the USB interface, switch off amp, etc. When I wanted to check the RS232 in the back of the K3 I noticed that the ground was disconnected (I removed recently the K3 from this position, and seems I forgot to connect it again). After I connect the ground to the K3 all started working properly right again..! That´s why a good ground is necessary!... 73, Jorge CX6VM/CW5W -----Mensaje original----- De: [email protected] [mailto:[email protected]] En nombre de Don Wilhelm Enviado el: Domingo, 12 de Septiembre de 2010 05:38 p.m. Para: Jim Brown CC: [email protected] Asunto: Re: [Elecraft] K3 RFI in transmitted audio Jim, Sorry about my phrasing, I did not mean to imply that it was strange that the varying V- current would cause modulation, it can and it will. What I intended to say was that the modulation itself might appear "strange", and may not be recognized as mmodulation at all. 73, Don W3FPR On 9/12/2010 12:34 PM, Jim Brown wrote: > > Don said: > >> Strange modulation of the V- line to the accessory can result, >> especially with SSB transmission, > Nothing strange about it, it's simple Ohm's Law. :) You have DC > current on the V- lead that reaches a peak value of at least 20A, so > there is voltage drop on that lead as predicted by Ohm's Law. ______________________________________________________________ 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
