Narrative:

I was the leader of a flight of 2 pipers (cherokee PA32 and lance PA32R). The #2 aircraft, aircraft Y, had an alternator failure and was following me in aircraft X. (Our call sign was xx.) he was listening to me on 128.95 and I was relaying ATC instructions for him. I contacted rdu ATC 38 NM out. They turned us to a 060 degree heading for the downwind leg for runway 23R. When we were 11 NM out, the controller switched me to 124.80. At that point, I wanted to let my wing man ahead because he was on battery power only. I called across, what I thought was ATC, that I was going to break high left to let my wing man ahead. At that point I broke and my wing man contacted tower on 127.45. I did not know this, and ATC got confused over what was happening. He was using another call sign. He landed runway 23R and I landed runway 23L. After landing ATC requested that we call them once in the office. This was only the second time I have done a flight of 2 and the first time I was lead. It was the first time for my wing man. I might have accidentally broadcasted my intentions on the wrong frequency. I am not sure, things were happening fast. It comes down to ATC did not know what was happening and confusion set in.
