Narrative:

The flight was from milwaukee, wi, to chicago miegs airport. Small transport X was on an IFR flight plan in good VFR WX. After establishing radio contact with chicago approach control the copilot preset the tower frequency for miegs in the radio, by mistake he put the tower frequency in the active radio. The copilot then went back to the previous controller to get the frequency for chicago approach again and reestablished radio contact. Chicago approach asked if we had visual contact with aircraft Y in our area. We had visual contact with the aircraft Y in our area and had been watching it. No evasive action was needed. Aircraft separation was at less than 1 mi. The estimated time of lost radio contact was 1 1/2 mins.
