Human Factors; Procedure
SFO was in a 28/28 shoreline configuration. The winds were calm to light so aircraft were coming in staggered and fast. It was a busy departure and arrival hour. Normally with these winds we would be departing the 1's; however due to taxiway closures we were departing the 28's. I was working Local Control ready to depart off Runway 28R with traffic on a few mile final for that runway; when I noticed a CRJ going missed approach for Runway 28L. When queried; the CRJ said they never received a landing clearance. I told them to fly heading 265; then cleared the departure on Runway 28R for take off who would be departing on a west on a 280 heading. I told the CRJ to maintain 3100. The CIC said they thought they heard him read back 2100; but my Local Assist said they heard 31. Instead of telling the CRJ to contact Norcal Departure on 135.1; I said to contact Norcal Departure. Unfortunately; the CRJ stopped at 21; and went to the wrong frequency; with the CRJ going around; it through me off. I should have ensured the proper altitude and given the appropriate departure frequency. I did hold the rest of the aircraft until everything was straightened out; but should have taken more time ensuring everything with the CRJ. I should also add that frequency congestion could have been a contributing factor.
SFO Controller described a below-MVA event when traffic on final for Runway 28L initiated a go around absent a landing clearing with traffic departing Runway 28R; the reporter assigning the wrong altitude/frequency to missed approach aircraft.
