[Elecraft] KX3 - Switching power source while operating

2017-06-28 Thread Terje Elde
Hi, I’m wondering if anything is known about how much of an intermittent loss of power a KX3 will more or less not notice, during full use (transmit at 15W), and during receive? Asking because I’m considering some power solutions, and wondering if it could be useful to switch between multiple

haven’t decided yet if I want a read made pack, or if I want to set the pack up myself. The latter would probably allow for easier removal of the cells, to charge them externally. For those of you in Europe, nkon.nl is a trusted supplier with good prices (though currently not shipping to Norway
