TRANSMIT DETECTION SWITCH TDS-15A

Mutes Vehicle Speakers When Transmitting HAM/CB Two-Way Radio

TRANSMIT DETECTION SWITCH TDS-15A
Can be used with CBM-U4 Products

  • The TDS-15A is an inline current sensing device that installs between a two-way radio and its power source switched ignition or battery.
  • When connected to a CBM-U4 or most Audio Interrupt Products, it can detect when a transmission occurs and mutes the vehicle stereo so a message can be transmitted quietly without audio from the stereo.
  • When the push-to-talk (PTT) key is pressed to transmit, the current change is detected and mutes the stereo upon transmission. When the PTT key is released, within three to 30 seconds (adjustable), the normal stereo play resumes.

What our Customer’s Say:

While talking to John, the founder of Rogus Innovations, John suggested that I try another one of his inventions called the TDS15A that mutes the car radio speakers when I transmit making it easier for the party to whom I am speaking to hear me.

I hooked up the TDS15A according to the clearly written instructions. It requires an easy one-time adjustment just like setting the squelch on a two way radio then the tiny unit can be hidden away under the dash. It works flawlessly and everyone I have spoken to over the ham radio can hear the difference as I do keep the car radio very loud to hear it over the throaty Mustang exhaust.

Transmitting music over ham radio frequencies is frowned upon in the ham community so this prevents that, and I no longer have to touch the car radio controls to have a conversation over the ham radio. Super idea, works well, simple installation. Makes using the ham radio in the car so much more enjoyable.

Thank you John."
