I cannot comment on the K1 but for the past two years we have powered our K2 in RSGB NFD off 4AH Gel Cells. Running at 5W output one gel cell will easily power the rig for well in excess of 6 hours We used 2 of these cells to cover our 12 hours of operating time and they were far from flat at the end. The only reason we swapped cells halfway through was to get rid of the annoying 'Lo Batt' beep which is a little too conservative with its threshold level. The K1 should last quite a lot longer. Incidentally GW4ALG entered the Battery Management Challenge in last year's NFD using 8 AA alkaline cells and operated for around 6 hours at 1W level - he had to give up when it became too dark to see, while there was still plenty of life in the batteries! This year in NFD we used 7AH cells at the 10W level with the same experience - see http://www.g4bra.org.uk/nfd04.htm. 73 Dave G3YMC http://www.davesergeant.com _______________________________________________ Elecraft mailing list Post to: [email protected] http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.
