After years of operation my K2 cannot be swithed ON properly. - Configuration: K2 (No. 3680) with KDSP2, KSB2, KNB2, KAT2, K160RX. - By switching ON the display shows Elecraft for 3 seconds and thereafter the last used frequency (28.15 MHz). - All keys and the VFO are inactive. - Current drain is 400mA (to high). - Noise of several relays during power-ON is audible. - Speaker brings (AF-gain dependend) audio for < 1 second and thereafter the audio is muted. - by changing TX power, the level appears on display as normal. - Transmit is not possible. - LED on KDSP2 extinguish after < 1 second (communication schould be OK) - 5 VDC and 8 VDC on the control board are OK.
Has someone a good idea how to de-freeze this blocked K2 ? 73, Ueli / HB9MFK -- Jetzt kostenlos herunterladen: Internet Explorer 8 und Mozilla Firefox 3 - sicherer, schneller und einfacher! http://portal.gmx.net/de/go/atbrowser ______________________________________________________________ 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
