My KX3 internal tuner works perfectly at transmit voltages above 10v. Below that value it will initiate tuning but finish at an SWR of between 3 and 6. When this happens if I connect my station 13.6v supply or an external 12v battery supply it will immediately tune to the expected low SWR.
Elecraft tech support was a bit non committal on this issue. They said that 10v was close to the minimum value for the relay drivers to operate properly. This is a bit strange as one does not have to operate long with internal NiMh batteries before the transmit voltage drops below 10v. An easy work around is to perform my portable tuning when I first start operating. Still this seems strange behavior for a rig designed to work on the internal battery pack. Is this normal operation for the internal tuner? If not, then what should I check? I thought that tuning at a lower power might help but the manual states the tuner operates at either 2w or 3w and the value is not under user control. ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
