Dynamic MIC Amplifier/Echo Chamber w/Roger BEEP 4 pin Cobra CB HAM

Yes, this works great for my Cobra 29. Just plug in and set on 7 both dials and your in business.

Love it..sounds great

This doesn't work properly. Only 2 of the 3 functions work. The seller sent back a return label but he has set it up so it cant be printed out?? Not the first time this has happened from what I read. Would have been happy with it being it worked right. So Amazon will handle it since seller has made it so label can't be reprinted.

No talk back so you can't hear it maybe it's my speaker I will change that out with another one this week

Works great. I like the way it sounds. Tip.. I use a pro trucker chrome mic that also has the chrome cord it seems to shield from squeal when using a talk back speaker. You can turn your dyna mic on a ltd 29 wide open with no feedback in the cab. Highly recommend

Works great after i found out the ground is only for show just hook up the positive feed to the echo box if you hook up both it will make all kinds of unbearable noises like like it did to me in my mack

This 𝗱𝗼𝗲𝘀𝗻'𝘁 make your radio sound any louder. All that it does is it allows you to add echo/roger beep to a radio that didn't come with echo/roger beep. Echo by itself 𝗱𝗼𝗲𝘀𝗻'𝘁 make any radio louder.

If you have a cheaper end radio and you want to sound louder, this is what you need. It installs easy, it plugs right in to the mic lug then you plug your mic into the lug on the device. Gives your voice that echo sound you hear on big radios with echo boards. I run my echo on 4 and the delay on 6.
