Following your instructions here and in the README for scan produced
absolutely nothing. It was only because I've been struggling with this
for so long that I know the frequencies by heart, that I noticed that
it was checking the wrong frequencies, and it took a bit of digging to
figure out how to change that.
(just add a patch against the README to your diff;)
You want a diff to add something like "By default, scan checks a limited
number of default frequencies. If you want it to check a specific frequency,
tune to that frequency (e.g. using szap/tzap/czap) and then use scan -c" to
the README? A diff seems a little over the top. I'm sure you could explain
this better than I, but you are very welcome to copy and paste the above
words into the README if you like.
