Here's a small problem that came up with my Yaesu FT-450at.

Connection plates between display unit and rest of radio has got corroded and when keying the rig on SSB,
there was a NNNNNNNN-sound behind transmit from display transformers.

Cleaned the contacts and put it back together - the sound is gone! Planning to add a extra GND wire between display unit and rest of radio later.
