[Elecraft] Found this super cheap battery box for KX QRP radio

Most AA battery holders, because they are not designed for high current
draw, have relatively high resistance, and you see a lot of voltage sage
while transmitting. Elecraft has made an effort with their internal AA cell
holder in the KX3 to mitigate this problem, but every external multicell AA
holder I have tried has suffered from high resistance and disappointing
voltage sag during transmit. If this one is different, that would be great,
but I wouldn't count on it.
