I have a Kenwood 440TS AT modded for 11 meters.
I use the MC60A desk preamp mic.
Im wanting to add an echo board/box to the radio and having problems.
3 different echo boards all work on cb radios but not this Kenwood 440.
So I have a small bot to put the echo board in.
I added an 8 pin mic jack to the box and a wired 8 pin mic plug straight through pin for pin.
I removed pin 1 audio and put the input echo cable on pin 1 and shield to ground.
The removed wire pin 1 added the the out of the echo board and then ground.
Echo board grnd and 12v+ wired.
turn on echo board and the radio goes crazy audio wise with bad squeal.
I tried 3 different type echo boards and the same problem.
Also tried the kenwood hand mic and same results.
Has anyone tried to add an echo board to the 440ts external.
I tried all kind of ways and still not working.
I take the same boards and put in a 4 pin box wired input and output and power.
tried on a cobra 29ltd and works great.
Am I doing something wrong on the kenwood?
I have installed over 50 echo boards on cb radios with no problem but the Kenwood big problem in Little China LOL
thanks for any help
