Narrative:

I left charleston and had good communications when I got to int. I attempted to call the approach control and tower with no success on the receiver. Assuming that I had lost communication, I squawked on my transponder 7600, then 7700 and waited for traffic to clear. With no traffic visible, I proceeded to land on runway 21. I was then approached by someone who filled out a report and asked me to call the tower. I called the tower and he told me I should have squawked 7600 first and circled the airport area until I got their green light, but I was under the impression they did not receive my transponder either and that is why I came in to land. It was severe clear and I exercised all caution.
