This is very easy to satisfy. Select ten AA NiMH cells of about 2500 mA-Hr capacity and a ten-cell holder and a quick recharger and you'll be set with a small light-weight pack good for many hours of operation on each charge. Cells of 2700 mA-Hr capacity are also available, but I've had some longegity issues with a few of those that I've purchased. YMMV. I like to have a duplicate set of cells (20 total). >Any good brands? RadioShack sufficient? I'll be carrying the >stuff about 3/4 mile (I'm 54 hi) I've used the following with good results, but there are many many good sources on the net: http://www.batteriesamerica.com/newpage3.htm Their ten-cell holder is a linear 1x10 array, while I prefer a 2x5 array. I've been using this pack with my K1 on camping trips since 2000. I've found nothing I like better as a power source for my K1. I tried the internal eight-cell KBT1 pack but removed it after a year. The K1 remains my favorite QRP rig of all time, especially for camp use. 73, Mike / KK5F ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
