XG1 battery voltage(s) reference needed

[Rick Commo]

Could someone with an XG1 please measure the battery voltage with the board
switched off and then the board switched on>  I need a reference point since
I have tried three batteries in mine and the yellow light always comes on.
My batteries were anywhere from 3.05 to 3.15 no load, but dropped to 2.9 or
less under load.

Thanks,
-rick, K7LOG

Rick,
You must have a circuit problem, either there is a bad component, or a component in the wrong place, a bad solder joint or something in the oscillator is drawing too much current.
Check U2 for 1.22 volts.  Make sure R9 is correct value.  Check voltage at the junction of R10 and R11 should be close to 1.5 volts for a good battery.

Allen,

I believe that you are correct and figured that my XG1 had too much current
draw.  I will do that as soon as I have the chance.  Right now am just a bit
busy getting a couple of computers built up to replace some boxes that
recently went belly up.  In a couple of weeks I'll be recuperating from some
surgery and plan on having my K2 and some other stuff upstairs with me to
keep me "entertained".  Will do the checking then.

73s & thanks,
-rick, K7LOG
