Another example of stupid hardware...

But if it's possible to interrupt scans, you could support some
experimental/ugly 'work-around'. On 'set-frequency()' just set the
card to some kHz less and scan up. Report station signal, if scan
stopped at the right point. Otherwise set to the required frequency
and report 'no signal'.
