I did not do a lot in the contest but just had some fun. I really had to tighten down the filters to hear anything.
What I noticed is that you really had to be on the exact frequency when the filters are tight to hear anything clearly. I did notice that folks were trying to call back and they were off frequency and the copy was difficult. I was able to get fast contacts because I believe that I was carefully matching the calling stations frequency. Anyway I have had a lot of fun.
