I got this little amp in the mail. I opened it up to see if the mod was done to it and it wasn't, so i solderd the wire to the 239 like it says in the mod. I hooked it up to a 148 with 1 1/2 watts. i turned it on and tried to check my match. set the meter, key down and calibrated. when i unkeyed, the meter stayed up. i switched to swr mod and meter stayed. turned amp off everything went back to normal. key up again to check power and got a bunch of static and when unkeyed meter stayed up. had to shut off real fast. any suggestion on problem.

turned dead key all the way down and it would not do anything. started turning it up and found the best setting to be 2 1/2 watts. works fine now.
thanks warlock

Hello,

Does anyone know where I can get a datasheet for the MOS RM3 transistor in the KL-40? I am not sure who the manufacturer is.

Thanks,

Phil

Crossbow, I got the same amp and I did not have to mod it. How long of a jumper are you using between the radio and amp? I'm using mine on a old 148 also and using a 6 foot jumper.
