Yes. if you have to carry it up a trail, LiFePO4 batteries are wonderful. I loaned by KX3 plus KXPA100 to AF6RT, who was hiking 2 miles with 2,000 elevation change with W6JTI to light up a rare 6M gr

This is the best source (quality, low price) I know of in the US. I bought a 20Ah 12V battery. They sell batteries in many sizes and shapes to fit lots of existing products. https://www.bioennopower.

Yes, a specially controlled charger is needed, but it does NOT need to cost as much as the battery. A 12.8V 12Ah battery (the capacity Rick bought) weighs 3.5# and costs $125 from Bioenno Power, and

Yes. These are relatively slow chargers -- 2A for the 12A battery, 4A for my 20Ah battery. 73, Jim K9YC On Fri,3/18/2016 8:45 AM, rick@dj0ip.de wrote: That's about what I paid for my battery. ($125)

Hi Reed, Yes, this amp looks quite reasonable, especially for use at the 50W level. The concern would be with others that lack proper filtering at the output. OTOH, I'd like the IM to be better if it

That's comparable to what Elecraft has been doing in the last year or so. They are/were a bit slow during that period because many guys were sending K3s back to have options installed. Most of those
