Not being able yet to buy one anywhere, I've acquired the better chips to make a Tweety Bird. Off to RS to start picking up the resistors and capacitors. Have the schematic. Y'all wish me luck.

it is a cap and diode combo on the activation button that makes the keyup noise .by changing out the cap to a lager cap you can make the keyup longer or shorter depending on the value of the cap.Wire Weasel -
I have heard both versions on-the-air over the years, and the CA 3045 definitely sounds better. The link with the schematics says that this circuit will produce a "decaying whistle" whenever the mike is keyed. What triggers this?? It is just assumed that the battery is disconnected when the mike is unkeyed, and connects when the mile is keyed up, producing the sound?

i use to have a guy who made me birdies and sirens but he must have stopped as he doesnt return my emails anymore .he made slow birdies,fast birdies,wind up sirens,i miss that guy...lol.....i still got probably 7-8 birdies and 2 sirens in use over here in my d104 collection.
i recently sold a rare 2 tone birdie to a forum member along with a mic i put it into for him .
but he made me a offer i couldnt resist:tongue:
Hello WW I was wondering if you could help me find schematics to this Tweety BirdNot being able yet to buy one anywhere, I've acquired the better chips to make a Tweety Bird. Off to RS to start picking up the resistors and capacitors. Have the schematic. Y'all wish me luck.
