Good morning, I am using the standard power cable that is supplied with the KX3. Using a digital multi meter and the built in voltage monitoring capability of the KX3, it looks like the supply voltage is dropped by 0.5 volts in the power cord when transmitting with 5 watts According to the built in monitor, the KX3 is pulling 1.6 amps from my gel cell.
The gel cell voltage drops also, but I compensated for that when I calculated the .5 volt drop in the power cord. It seems to me that a larger gauge wire is called for in the power cord. Also, I can't get the KX3 to transmit more than 5 watts. If I turn the power up to 10 watts, it transmits at that level briefly, then turns the power down to 5 watts. It must be some voltage sensing circuit that does it. The supply voltage is showing 11.4 VDC when keyed.. So what about the gauge of wire for the power cord? Do you think we need a larger sized wire? 73, Dave, K4TO ______________________________________________________________ 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 Message delivered to [email protected]
