Radio question and cup holders question

I posted this on the other Mercedes forum (as a general radio question) with no response.

As many of you may know, I have recently purchased my first 90s Mercedes (after all of my previous ones being 80s models) and this latest one has me with a question about the radio.

When I turn on the radio (original) in my '93 (W140), it will occasionally make a "MMMM, MMMM" sound, almost like a cell phone that is on vibrate will sound. Is this normal or is my radio going out/have an issue? I know my antenna is broken and will not go to the top, so dont know if its trying to tune in a station or what? It will tune in several stations and even on one that is getting good reception, it will occasionally make that sound.

I have an owners manual, but I havent looked through it yet. I looked in an online manual, but it dont even mention the radio.

Also, where are the cupholders in my '93 W140? I thought in the console, but I cant gain access to any?

Thanks in advance!
