Narrative:

A C-172 was cleared for a low approach only due to regional jet traffic following him. At the same time; the C-172 was advised to enter right closed traffic following the low approach. The pilot acknowledged going into left closed traffic and was corrected and again told right closed traffic. The C-172 did not perform the low approach as assigned but continued and did a touch and go. The regional jet subsequently declared a go-around and commenced to go around. The C-172 was then advised runway 6 cleared to land. The pilot of the C-172 never came to a complete stop or acknowledged they had radio issues. The C-172 then started its takeoff roll from the touch and go and the pilot then started to squawk 7600 only after realizing there was something going on. The pilot of [the] C-172 then called the tower on the upwind on the radio stating they were entering right closed traffic. The regional jet then came around on the left down wind after the go around and landed without further incident. The C-172 then came back around on the right downwind and landed after the regional jet without further incident. The pilot of the regional jet then called the tower and stated that everything was fine and they didn't mind going around and actually enjoyed the scenery. Only after speaking to the pilot of the C-172 did he acknowledge they were having radio issues only after seeing the regional jet going around over him. The C-172 pilot was very apologetic and stated they would pay better attention to the procedures and the radio the next time. If there is an issue with a radio in the airplanes and it is known to the pilot; have it fixed prior to putting the aircraft in the air. Pilots; student pilots; controllers; and controller trainees [should] know all procedures in the event of a NORDO incident.
