Vertex VX-5500 Front Speaker

[aaronroth]

I have a 5500 and whenever I plug in a rear speaker, the front speaker stops working. It doesn't matter if I have the radio set to front, rear or front and rear, only the rear speaker works.

Any idea if this is a problem with the radio, or if I'm doing something wrong with the programming? I e-mailed vertex, but they have yet to respond.

Thanks for the help.

There is mechanical switch built in the external speaker jack. This is the normal operation for most of vertex radios. The good news there is a very easy way to fix and mod the radio so the internal and external speakers work at the same time.

All you need to do is add a solder jumper on J2004 pin 1 and 2 on the main control board.
