KX2 Power supply

Bill Lederer
Friends:

I like to use my KX2 in my office with a wire out the window to a tree,
largely for listening, e.g. to ARRL code practice. I normally use the
internal battery and charge it up ever couple of weeks.

I am wondering if KX2 owners have used a DC supply to power this--short of
getting an Astron or equivalent--one that is just the right size that can
power a 12-watt radio.

Thanks.

For an AC supply IMHO there is only one choice.

Bill,

I don't know if this helps or not, but for Field Day, I used a deep cycle
marine battery to power my KX2. Worked like a charm.

What a great list!  Three answers before I got downstairs!

Thanks all.

Bill,

Take a look at the Pro Audio Engineering power supply.  Although it was
designed initially for the KX3, it works very well with the KX2.  No RFI
on the ham bands, so you can regard it as a noise-free switching supply.

I use a Bioenno Power LiFePO4 BLF-12045W - 12V 108W 54Wh to power my small radios, and a larger for all day field trips, such as supporting fund raisers (Diabetes, Lung, MS, etc.) where I am in a remote position all day. I see from the specs that the KX3 pulls ~150 mA during RX. That's 360h on a full charge. Of course I need to recharge it, but you do that now. And I have the added bennie of using the batt for all sorts of portable ops. The bennie of the ProAudio is plug and forget. I think the KX2 has an amp hr meter? So you would know when to recharge. Another bennie of the batt is that there are no cables and PS lying about...I am annoyed by those when I need to use them.
