I found an old Cobra 146GTL in a closet. I hooked it up but it does not power on. Can someone give me some hints on what might be the problem? I looked inside it and found no hints of smoke or anything burnt up. I just can't figure out what the problem is.

Thanks
 

you check the fuse inline with the power cord ? .....protect diode down around where the pos/neg wires go into the board ? ...they need not look burnt to be bad.
 
Umm, how 'bout the "CB/PA" switch?

Just asking.

And that radio is old enough the power switch could be bad, as well. I suggest a good, thourough look inside for any sign of a 'kaboom' moment some time in the past, like a burned foil trace on the circuit board, or burned parts attached to the inside of the power socket.

Nothing looks smoked in there. I checked the diode and the switch with my ohm meter and they work fine. Still don't know what the problem is. Anyone else have anymore hints?
 
I finally got around to looking at the radio real close. After doing a little testing with my Multimeter, I found that the solder on the power switch had cracked. After a little soldering, I got that baby going like a dream.
 
I guess the 146 came before the 148. The 146 features are just about like a 25 but includes Voice Lock, and Side Bands(LSB, AM, USB). That is all that I see that is different. Maybe someone else has some other opinions.
 
the 146 came after the 148 here, they came in 40 and 80ch versions and are a decent ssb radio but single conversion rx on am, it is hard to find one that sounds bad once it is aligned, this is a president ar144 i put highband on, it uses the same board as 146

looks like my uniden pc244 is the same as my uniden?i need to do some mods for this radio it does not swing much..does some one have any mods
 
look where my amc preset is set compared to youres lol, my am is set at 95% modulation :D
 
both of my 144's use nec d2824c pll chips, thats why i built the oscillator board for extra channels
