Jim,

About 30 uA with the radio off, and about 1 mA with it on.

OK so if this board is not installed, how much power does the KX2 draw when turned off?

Wondering if I should sell my K2 and get a KX2.
Anyone know if you can receive the AM broadcast band?
I can on my KX3 with the auto-tuner and wonder if there is any ability to listen to the broadcast band on a KX2.

 From the KX2 manual (which is online)

Sensitivity (MDS), 500-Hz bandwidth
-136 dBm (typ.), preamp on. Note: Sensitivity rolls off significantly
below 3.0 MHz
due to protective high-pass filtering. Preamp-on MDS is typically -105
dBm at 1.5
MHz, and -80 dBm at 1.0 MHz, sufficient for emergency AM broadcast
signal copy.

I interpret this to say that it's good enough to hear strong local
signals, but it's not an AM DXer's receiver. The high pass filter has a
turnover of 3 MHz, is 30 dB down at 1.5 MHz, and 56 dB down at 1 MHz.

If you're looking for a nice AM BC RX, consider the Tecsun PL-660 and
PL-880.

73, Jim K9YC

Way less than the self-discharge of the cells.  30uA probably is too.

So with the new card installed it would take over 83000 hours to drain the battery.  WOW that’s 3458 days almost 9 years.
