I hope this to be a defect of ATH5k. ATH5k cannot find proper connector automatically.
But without using debugfs, connectors cannot be switched. So I hope that it cripples
signal for many users that do not know about this peculiarity.

I have no longer observe any drops in signal. Signal is pretty flat now.

I has been used MadWiFi before. I have moved to ATH5k because madwifi caused kernel 
to crash for more than two atheros devices and it has other strange functionality
and it is no longer supported. Last MadWiFi versions are no longer functional at all.
For example a new MadWiFi-ng cannot recognise 2nd device.

  For me, madwifi did 15 switches, selected better connector, ant then it 
no longer changed connector.
  But after one month of uninterrupted run, MadWiFi suddenly switched back
and signal has been dropped for unknown reason :(.

OK.
