TR-2400 Unwanted Noise: Tone or burst at tx                        2-13-80


For complaints of a tone burst type noise, or simply a noise, at initial
key down, suspect either a broken losse component, or incorrect valued
component on the RX TX  unit.

On the RX TX unit, Q16 emitter, check C82, a 33 uf tantalum cap for broken
connection.

If you find a 22 uf cap at C82 replace it with a 33 uf cap.
