TED250 - CTCSS ENCODER/DECODER
(PL, Channel Guard, Quiet Tone)


TED250 encoder/decoder from Hamtronix is a programmable device for encoding and decoding CTCSS tones. Thanks to SMT technology used in some components, TED250 is small enough to be mounted inside any mobile radio and even in some portables.

 

Easy to install, you just need 12V DC and the unfiltered audio (discriminator) from the receiver. When the selected CTCSS is detected, a 5V logic output goes low. This logic can be connected to the TONE input pin of Elektra 2000 or any other controller. TED250 also offer an filtered audio output without the received CTCSS tone in order to transmit a clean audio with or without a different CTCSS on the transmitter. 

 

TED250 is able to encode and decode all 39 standards tones used by the major radio equipment manufacturers. This unit is able to encode and decode 8 extras non-standard tones, not available in most radios for best security in commercial repeaters, since most amateur radio equipment don’t carry these extra tones.
