Ggareth,

Not used on the VHF radios.
Only the 900 37 series Spectras had the little plug in board for Hear Clear.

So what you are saying is they will not power up?

[mts2000man]

hi will yes they do not power up at all that's all 300 and they have all had this board removed regards gareth

Let's start with the simple stuff. Are the green and orange wires from the remote mount or the red wire from the accy plug on the dash mount connected to 12VDC?

Let's start with the simple stuff. snip

A model number? On the Spectra serial tag the ID No. is actually the radio's model number.

IE: D43KMA7JA5AK is a VHF 50 watt dash mount radio with the standard push button controls.
