ECHO BOX PROBLEM?????

[gwhpnut]

I have a Galaxy 959 CB radio. I want to ad a galaxy echo box to the set up, but when I hook the echo box up to the radio, it causes a buzzing sound in the transmission and I cannot be heard. the radio works great, but if I hook up the echo box this problem presents itself. I have both the radio and the echo box hooked to the same power wire, is this the problem? does this cause a feedback to set up? I had the whole rig in the shop twice, and they say it works great on the table? this is driving me nuts, so any help or Idea would be helpful, thank you, victor

does it work without the box inline? sounds like a bad mic wire or ad solder jo, otherwise turn down the mic gain.

i agree with carl . also is the powersupply big enough to handle both
the radio and box?seeing how the problem starts when
the box is added.if all else fails buy a galaxy echeo desk mic
these sound good
