On two occasions (18 March and 29 March) I have observed a birdie during 
Ka-band observations at sky frequency ~34.040GHz on ea22.  The strongest 
line is present in IF B, but there are other, lower-level lines in IFs A 
and D.  There could be additional signals that are not detectable above 
the noise in the bandpass plotting tool.

I have attached plots from 29 March as an example.
