Regarding using 16.7 V LiPo battery and regulator with KX3... I have been quite successful using 4S LiPo batteries for 4 years now, first with my FT-817, now with my KX3. My equipment is shown here: http://kr7w-sota.blogspot.com/ Scroll down a bit for the battery stuff. If you view the Flickr photos- be sure to turn on the 'show info' option (upper R corner) for more info.
I can charge my batteries in the car to/from the operating site from the car accessory power jack. At home I use a 1 amp wall transformer or connect it to a ham radio power supply- like Astron- to charge at 1/2 amp. For more info, email me off list. FYI and Best Regards, Rich KR7W ______________________________________________________________ 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
