[Elecraft] KX1 switches off when antenna connector shorted
Is it normal for the KX1 to shut off if it sees a short across the BNC connector (no RF applied)? I'm trying to use a 4:1 Guanella balun (which looks like an electrical short) but the KX1 shuts off if it's in line. I tested this behavior by simply shorting the BNC, also. 73, Casey http://cloud-warmer.blogspot.com __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

Casey, That can happen if C44 fails shorted. Turn the KX1 on and measure the voltage at the center of the BNC jack. If it is not zero, replace C44. 73, Don W3FPR On 8/2/2011 1:34 PM, NA7U wrote: Is it normal for the KX1 to shut off if it sees a short across the BNC connector (no RF applied)?

Oddly enough I tried a different power supply and it was OK. Then I tried again the previous PS and it was OK. ?? I will check C44, however.
