Alkaline battery drain on FT-817, even when off
 

I seem to notice that I get a battery drain on the alkalines in the
FT-817, even when it is turned off with nothing else attached (ext
power supply). Has anyone else noticed this condition? I've come up
with a home brew case that will use a SLA battery to externally power
it, but am still concerned about any (even if small) continuous
battery drain. Any comments or advice would be appreciated. Thanks!
