First Post - Sorry if its in the wrong section.
Hi, I have a question about a tone I recently heard over the Cliffside Park, NJ police channel. Their HQ consoles generate a "key-up" tone upon beginning of transmission. Their mobile and portable radios do not appear to make generate this tone upon key-up. It is generated every time the HQ console keys up. I've heard this sound in numerous NYPD transmissions as well. Does anyone know what this type of key-up noise or repeater access is called? Thanks for any help.
