Oops, sorry about the double post previously.
The "birdie" problem is fixed.
I was suspicious since it was a clean modulated tone.
Read the manual (Very carefully this time), yup, it has a 25 kHz crystal calibrator.
What was not obvious is that it is controlled by the mic gain knob!
The birdies are now gone.
Lessons
1- Read the manual first.
2- See lesson 1
Happy New Year
