Hello Joe,
Out portable yesterday - KX3 powered by an 8400mahr LiFe battery pack, which was fully charged that morning before I started operations. Antenna was a Buddipole vertical on 7119, SWR1.1, with j, C and L components all zero (ie on the antenna's resonant frequency). KX3 running at 15W out. After an hour of operating (SSB), the KX3 started to wander off frequency by a 1Khz on transmit. A contact noticed this during a QSO. The battery showed 13.1v at the time. I changed the battery, and with the new one the KX3 worked normally. Is this a low battery issue, or do I need to look elsewhere?
I use my KX3 down to 10 volts an lower without any frequency change. I suspect rather great transitional resistance, especially when transmitting. Are the wires from the accu to the KX3 thick enough? Are the connectors are stable enough (no defective/intermittent contact)? 73/72 de Ingo, DK3RED - Don't forget: the fun is the power! www.qrp4fun.de - [email protected] ______________________________________________________________ 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
