well maybe , it depends on what rail road your near , some use a new trunking radio system and unless you've got 20 scanners going your never hear the whole conversation (google how trunking radios work to see why) but in most cases the block controllers talk to the trains via radio that can easy be scanned to find the frequency , now the block controllers talk to one another via a land based data line so you'll never hear them talk to one another as they hand off a train to another block
also if your close enough to a mains yard you'll hear the switchmen and the drivers converse as well but you gotta be close as there radios are low power so don't go very far (1 mile maybe)

Turn up your RF gain. If that isn't the issue, then the mic may be damaged. Try a new mic.

do you have a talk back modification you don't know about or there was one and someone didn't remove it right or the speaker was wired wrong check your radio ground .or try a diffrent mic.

The Uniden Solara is a MARINE RADIO not a CB. Marine (boat) radios operate in the VHF-Hi range and CB is in the VHF-Lo range. You also need a license to operate a marine radio, or you can identify yourself with the name of your boat but you MUST be in the water.

first they are not a phone, they are a 2 way radio walkie talkie and will not work for telephone communication.

you need a swr meter to check your standing wave.

Hi,

Based on your description, possibly a microphone problem. Either that or a wire is cut/open in the microphone cable. Remote possibility is the FM modulator circuitry internal to the marine radio.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.
