Anyone remember a sitcom which I think involved a family who lived in a home that was also connected to a radio station or they had the radio station upstairs? I vaguely remember this one from when I was younger. Any info on the name or other facts would be appreciated.

no, I don't know what you are talking about sorry.

widower DJ Dad takes his two daughters from LA to Portland OR for a new job in radio

it was a DIFF'rent Strokes spinoff w/ maclaine stevenson and
the girls were Kim "witch mountain" Richards and
Donna "Angel - hollywood hooker by night" Wilkes.

Hello Larry was not a spin-off of Different Strokes.
HL aired right after DS and at some point during it's run, in an attempt to boost ratings they did crossover episodes by making Larry and Philip Drummond army buddies and having the station Larry worked at being bought by Drummond's company.

I am familiar with Hello Larry and am pretty sure that was not it. I think it might have been on before that. I thought Hello Larry was a spinoff of DiffSt. or at least the character debuted on it. But that last poster sure seems like a DS expert.
