That's a prime indicator that your wall wart (charger/adapter) has died.
Don't ask me why, but it seems to be a common happening with the SC-150. Of
the three I am personally familiar with (mine and two friend's), both of my
friend's wall warts bit the dust. And you aren't the first person to post
this problem on here or alt.radio.scanner. It's been a defective wall wart
every time. There is a "fuse" wire inside the wall wart on the AC side that
breaks if it is overloaded or just gets too hot too many times for too long.
That's the way these Class 2 AC adapters are designed. I'm always careful
to unplug my adapter as soon as I'm done charging the battery, maybe that's
why it's lasted longer than what seems to be the typical lifespan

Not long ago, as a test for a friend, I did power my 150 from the charger
only with the battery unplugged, worked just fine. I wouldn't want to do it
for an extended period of time, not knowing how the power circuit in the
scanner is built, but it can be done.

Take the wall wart to Radio Shack, and match the specs and plug with one of
their universal AC adapters, and you'll be back in business.

Any further questions, ask on here, my return email address isn't valid.

om...
Ok I broke out my old uniden sportcat 150 , because I finally bought a
new battery for it.
Here is the situation...... when I plug in my wall charger into the
sportcat.... the voltage drops down to 1.38 (using the WX and L/O
battery monitoring trick) from 1.58 . Also when i am scanning just
using the battery pack & plug in the wall charger the "Batt" icon pops
up & a beep goes off every minute or so.
I no longer have the manual for the sportcat so I am not sure what
this means.... I assume that the batt icon & beeping means that it is
the low battery indicator.

Also I would like to know IF the sportcat can operate with the battery
pack out of it & the wall chager plugged in? Because it wont for me.

I am trying to figure out if I have a wall charger that is bad or the
female charging jack(on the sportcat) is bad.

any help?
