The sad irony is that 159.8025 may have been the quieter channel. My bet is on a dyslexic guy, like me, programming the radio. Never thought I was, but after ten years and several thousand sets of call signs and frequencies, I find that I need to triple check things before I hit the send, otherwise I may have transposed letters in the call sign or switched a number around. And I went well into my 40s before I even realized I did that. Thought I needed glasses, and glasses didn't fix it.
