The VHF communications problem associated with command module reception of lunar module voice during ascent and the early part of rendezvous resulted from a low squelch-sensitivity setting in the command module VHF system. Future crews will be briefed on procedures to prevent this problem.

The second VHF voice problem during ascent and rendezvous is attributed to the use of the lightweight headset by the Command Module Pilot. S-band voice data indicate that during the time period when VHF voice to the lunar module was degraded, the voice was also degraded on the S-band link.
