Tweety Bird Whistle

   

Tweety Bird Whistle With Repeat 

 

The devices on this page are identical to each other except for minor changes of components and wiring, thus only the pictures of the Tweety Bird Whistle are shown.

This sound is available in two series. Regular and "Sure-Fire-Series"... Regular series is  identical to the tweety bird whistle made during the 70's, except we do not use PTP (point to point) assembly anymore. PTP, although it made the device very small, a lot of the transistor arrays were damaged during assembly due to direct soldering to the IC.  Also, costly 1/10w micro resistor were needed in order to allow the device to maintain compactness.  

In 1987 we started using a small PCB as our foundation. It has a "recharge time" needed between key-ups and the longer the wait between key-ups the better it whistles until it reaches full capacity. 

Then there is the "Sure-Fire-Series" which has a small relay keying circuit incorporated on the printed circuit board that insures the whistle to be at maximum at every key-up. Both series has a rapid repeat. The whistle must be special ordered to obtain a "Sure-Fire-Series" or the normal whistle will be sent. There is a slight price difference to defray the added cost of the relay and supporting circuit. 

When activated, either manually through a switch or automatically through the P.T.T. system of the radio, this device generates a mellow whistle which starts at the low end of the audio spectrum and increases in frequency until the whistle goes out of the range of hearing.

 

 

 

 

 


Cosmic Whistle

This whistle is a tweety bird with a lower frequency than the original series. It has all the characteristics of the tweety bird.   The rapid repeat is slower and more pronounced in a mellow frequency shift. "Sure-Fire-Series" for this whistle is also available.


Sonic Whistle

This whistle is a tweety bird with a higher frequency than the original series. It has all the characteristics of the tweety bird.  The rapid repeat is faster and less pronounced in a mellow frequency shift. "Sure-Fire-Series" for this whistle is also available


It's A Gas 

This sound is as the name implies. (PEW). It has a distinct sound all it's own and is not like the digital sound from a mule. This sound is more like the sound produced by a human and the rapid repeat is not available.  Also available in Sure-Fire series.


Cosmic Cat

This sound is a electronic representation of the meow of a cat. It can be manually triggered through a switch or automatically through the P.T.T. system of the radio. The difference in this device and the Tweety is that this one has a lower frequency of tone and the rapid repeat is not available.  They look almost identical. Also available in Sure-Fire series.
