[TowerTalk] HD-73 Rotator issues

[Gene Fuller]

Hi Dan -
If the voltage is noncritical enough to accept 5.1v instead of 4.7v, perhaps 
just a resistive voltage divider would get you through the weekend, or, if 
the load current varies quite a bit, a series of plane old diodes, allowing 
for the difference in voltage drop between silicon and germanium, might 
accomplish the task, or foot that matter, three nominal "!.5" volt batteries 
would get you pretty close. It all depends on how important the contest is.
