NBC broadcast schedules from 1951, 1952, 1954 and 1958. This is the best ever guide to see which studios were being used at a time when radio and TV were sharing space at 30 Rock, and looking for studio space around the city.

Here are some keys to the Abbreviations here, so you can better understand what is going on. First, the -L is for Local and -N is for Network. Studios A, B, C were live studios at NBC’s Uptown Studios at 106 Street and F was the film projection studio there. 3H, 3A, 3B, 6A, 6B, 8G and 8H are at 30 Rock. Intl = The international Theater, Cen = The Center Theater, Hud = The Hudson Theater. CHI means the show is being done at NBC in Chicago, same for Wash = Washington D.C. and PHIL = a feed from Philadelphia. Notice “Camel News Caravan”, and some others are (C & F) which means the show is live with some film inserts.
