    Help, I'm Bipolar, I think?

    Thanks Rob, I know there is a joke in there somewhere with the "tranny". I was hoping to avoid, testing each one at a time, but I will. Back to the other question, is it the current flows into the transistor thru the collector and when it reaches a certain point it shuts off or goes to...

    Help, I'm Bipolar, I think?

    Bipolar junction transistor - Wikipedia, the free encyclopedia Could someone explain to me the conventional flow of electrons in the NPN trainsistor? I have read and reread it and just don't get it, I know this isn't electronics 101, but isn't it just like a gate or a switch, to turn on/off...

    COBRA 25 LTD INCOMING AUDIO PROBLEM ?

    When you say it receives? Does that mean the needle moves? or can you hear the bench radio thru your speaker? Or can you hear people talking thru your speaker? Sometimes your radio/needle will just pick up rf from the bench radio. You'll need at least a DVM about $20 to get started. There's...

    B&K 2040 Signal generator and alignment

    I finally got a nice one with a online manual. I have two questions if someone could help. 1. Can the output of the signal generator be used to go to the imput mic connection for generating a constant signal for alignment, versus the "ahhhhhhhhh" into the mic? If so is it done with a coax of...

    COBRA 29 with IRF510/ IRF520 / ERF2030 Question

    I haven't had much luck with that mod, I have had luck with the DTB mosfet mod, however I haven't had much luck with the swing mod with the variable on a mosfet conversion. What I get is that it works on the bench but in a vehicle it is hard to keep the dead key set. You'll set the variable to...

    Uniden PRO520XL modification?

    Just a guess, I don't know the radio, but probably a way to reduce the carrier so that they could run an amp.

    Whats so wonderful about these things?

    Come on now, this is a tool for a tool. With this unit you can sit in the truck stop and hide in the sleeper(or your mom's basement) and act like a total fool, versus just a fool. I never could figure it out, ranks right up there with "I got to go see where the fire truck is going?"
