I have a Telinga with stereo DAT-Mic and I can't say I can find this at
all.
I've recorded in Hungary last month and many of the subjects were
warblers like river warblers and sedge warblers and savi's, along with
a good number of crickets in the environment. The frequency response of
the Telinga did get seriously wearing after a couple of weeks of
recording - I need to investigate putting my Sennheiser MKH30/40 in
there instead and/or getting into shotgun mics for these kind of
subjects when they're up to 20 feet away. The HF heft of the Telinga is
probably great for its main use for birds over 50 feet away, but it's
way OTT for closer subjects.
The dish itself does ring probably around the frequency you mention on
mechanical impact, which is a drag when small insects hit it, but that
isn't anything like a continuous hum
