When I went to college down in Arkansas, I used to operate with John, the
original N5DX (now an SK). He was a dedicated DXer and a heavy smoker, and
he used to blow the smoke into his C-Line while he operated.
When I showed up with my brand new (and smoke free) C-Line, this was
immediately apparent as my dials were the light Drake blue, while John's
were *green*. Inside, the radio was covered with the gunk Ian describes.
If that doesn't drive you away from smoking, nothing will...
