Gonna riff on the idea that switch changes don’t produce anything (“guess I’d better ask someone”).
Bad antenna choice coupled to typically poor antenna mount (past other systems where applied diligence will improve performance) seems to make radio controls a sort of joke.
1). Hear, versus can’t hear: instead of subtly modifying signal for more pleasurable listening.
2). Only the volume control makes changes: pretty well the experience of most everyone who throws a CB into a vehicle.
— There are two systems the heart of a radio system. Actual radio just one of many choices can be plugged-in.
A). The Antenna System is the ballgame.
B). The Power System needs to be noise-free and capable of less than a half-volt dropped once one keys the mic.
— Until these are given precedence the chances of an unresponsive radio could lead to a half-baked conclusion that CB just isn’t worth much.
— As a daily user of AM-19 for work (long distance truck driver) I encourage anyone reading this to start over with some research and list-making. Tools, supply, and installation-details: take things a piece at a time.
I’m using a GALAXY DX-959b AM/SSB radio where a half-dozen “sound” combinations can be set AT the radio. From far rural areas in the deep of night to some of the countries busiest metros mid-afternoon.
I but rarely choose to run any Squelch, and RF Gain is kept wide open. While I use Amateur noise-reduction accessory gear, the HI-MED-LO Tone Switch does most of the work in conjunction with the NB-ANL Switch to modify relatively quiet signals reception.
— Without a decent antenna & power system-pair that switch combo just wouldn’t do much to help me keep abreast of the DISTANT signals I wish to capture.
In mobile CB everyone is moving constantly. A few seconds is all one might have. Thus, the rural areas I can leave NB off as local noise doesn’t prevent me from hearing guys farther out (versus in-city where it’s not possible other considerations notwithstanding). It works as intended .
IOW, an unresponsive radio is telling one he needs to fix the BIG problems so that the little ones can then be modified for listening sake.
No real change Local vs Distant?
It’s not the radio.
— Get some altitude to look over how well it all works together.
