Wow, a handheld D710.

I just noticed that the RC-D710 APRS display head has a spec
voltage of 9 to 11 volts.  Since 8 nicads would give 8.8 to 11.2
volts, I think I will give it a try.

8 NiCd's taped to the back of the Display Head, will let me use
it with any HT (without having to purchase the $80 PG-5J
interface which contains the 10 volt regulator) Maybe.

Anyone done this?  Here is my schematic I am working on:
