Don't feel bad.

We use ours pretty much every time we leave the pattern, and sometimes
we still have to do a full spin to clean the contacts. With us, it's
normally the first digit, as ours normally always seems to be a 1, 5 ,
or 0. The 2, 3, 4, and 6, and 7 sometimes get dirty in that slot.

Now that I think about it, I can't believe how often I'm told to squawk
5304. G
