[Boatanchors] Transmitter Chirp Question

[rhulett1 at comcast.net]

My Eico 723 chirps. Besides the crystal, the screen bypass capacitor and feedback capacitors, are there any other typical causes for this.  I owne d one of these as a kid and chirp was never an issue.  In fa ct, I've never owned ANY rig with this problem.  Anyone who experienced this problem with an Eico 723, Heathkit DX-20, or similar simple transmitters manage to determine the problem and solve it?
