How do I get my CB radio to sound like a Motorola consolette.
You don't.
I have a robyn CB transceiver and the speaker works fine but take notice between the two a Motorola consolette has a nice heavy sound and it seems to have hold on to the squelch noise at the end of the transmitting but the base station cb is more of a popping noise when someone else releases the PTT button.
So, the Motorola is in carrier squelch? Motorola, and several other manufacturers went to a great deal of time, effort, and money, to eliminate the squelch tail entirely. Put a pair of Motorola radios together on PL or DPL, and so long as signal strengths are decent, all you'll ever hear is the PTT button being released on the other end - no squelch tail at all.
If that's what you're shooting for, you could maybe change the time constant in the CB radio's squelch circuit to reduce it to a click. Or, use an audio delay chip, and mute the audio before the squelch tail hits the audio pa, in which case you won't even hear a click.
Or, you could do nothing, and settle on the fact that a cheap CB radio is not a multi-kilobuck commercial/public safety grade radio, and will never sound like one.
