'pips' heard on LW and MW with my ATS-909
 

Hi,

I have a Sangean ATS-909 with the Super-909 upgrade and one thing I
notice (which may or may not have been there before the upgrade) is
that on unused or faint MW / LW frequencies, I can hear little 'pips'
every 1/2 second, which exactly matches the flashing of the ":" in
the time display. I can only hear the pips in 'AM' mode, not USB or
LSB (though of course, all broadcasts are in AM mode on MW/LW!).

Are these pips a 'feature' of the 909 or only after the Super 909
upgrade? Has anyone else noticed this before? While it isn't 'the
end of the world', it is noticeable.

Regards,
...Francis Byrne
