took place on October 14. It began with a view of a card reading "From the Lovely Apollo Room high atop everything", recalling tag lines used by band leaders on 1930s radio broadcasts. Cunningham served as camera operator with Eisele as emcee. During the seven-minute broadcast, the crew showed off the spacecraft and gave the audience views of the southern United States. Before the close, Schirra held another sign, "Keep those cards and letters coming in folks", another old-time radio tag line that had been used recently by Dean Martin. This was the first live television broadcast from an American spacecraft (Gordon Cooper had transmitted slow scan television pictures from Faith7 in 1963, but the pictures were of poor quality and were never broadcast). According to Jones, "these apparently amiable astronauts delivered to NASA a solid public relations coup." Daily television broadcasts of about 10 minutes each followed, during which the crew held up more signs and educated their audience about spaceflight; after the return to Earth, they were awarded a special Emmy for the telecasts. Later on October 14, the craft's onboard radar receiver was able to lock onto a ground-based transmitter, again showing a CSM in lunar orbit could keep contact with a LM returning from the Moon's surface. Throughout the remainder of the mission, the crew continued to run tests on the CSM, including of the propulsion, navigation, environmental, electrical and thermal control systems. All checked out well; according to authors Francis French and Colin Burgess, "The redesigned Apollo spacecraft was better than anyone had dared to hope." Eisele found that navigation was not as easy as anticipated; he found it difficult to use Earth's horizon in sighting stars due to the fuzziness of the atmosphere, and water dumps made it difficult to discern which glistening points were stars and which ice particles. By the end of the mission, the SPS engine had been fired eight times without any problems. One difficulty that was encountered was with the sleep schedule, which called for one crew member to remain awake at all times; Eisele was to remain awake while the others slept, and sleep during part of the time the others were awake. This did not work well, as it was hard for crew members to work without making a disturbance. Cunningham later remembered waking up to find Eisele dozing. Conflict and splashdown Schirra was angered by NASA
