Narrative:

*Analyst's summary: small aircraft twin doing touch and go's at night at sanford regional airport, fl. Radio reception ceased so instrument and trnee decided that the tower had closed for the night. They continued in the pattern for touch and go's. Radio reception was intermittent between noise (attributed to new generator). On final approach for runway 9 they saw another aircraft and faintly heard someone say there were 2 landing lights on final. The 2 pilots then heard a voice they recognized as the tower chief come on and advise an small aircraft not to descend any lower. Tower controller then cleared the small aircraft twin to land. Reporter called the chief next morning at home and discussed the situation. Chief said he was still in the tower and had heard pilot of small aircraft whose voice he recognized and saw the 2 aircraft on final. So, he came on the air and separated the 2 aircraft as he saw that less than standard separation had occurred. They discussed how to increase safety at night with traffic at the airport and chief offered the advice to 'listen up.'
