While making some baseline measurements on my KX1 in preparation for the install of the KXB-3080, I discovered a mysterious 5 ma draw with the rig turned off but connected to an external 12v battery pack.
It turns out that the K6XX visible tuning indicator I have installed draws 5 ma continually regardless of the position of the power switch. I did the installation according to the instructions from Tom N0SS's website. The indicator works great, and is a wonderful addition to the KX1, since you cannot easily zero beat the a received signal (the sidetone menu setting mutes the received audio, you need to have a good "audio" memory). I just wonder if this constant 5 ma draw might pose a problem if you leave batteries in the internal battery holder unused for a long period of time -- potential leakage perhaps. It's not likely to be an issue one just installs batteries for a weekend's use, then takes them out. But before I had the tuning indicator, I left my first set of lithium AAs in for about 6 months. After I'm done with the KXB-3080, I may look around for another point to pick up V+ that is switched by the power switch. 73, Mike N2HTT _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
