[Elecraft] K3: birdie on 50.045?

[Dr. Werner Furlan]

when I am on 50.045.05 with PRE on I hear a low continuous tone. With 
PRE off it disappears. When I twist the shift, the tone gets lower or higher in 
frequency. (lower when shift to the right) 
When I switch the filter from FL5 (500) to FL4 (2100) the tone appears at 
50.045.95.
The tone obviously comes from inside the transceiver, because switching 
the antenna does not change it. 

Can anybody this phenomenon?
