The Radio Information Board

Well I installed a 730/630 setup. Checked on bench prior to install, all good. Before install did the 160 ch upgrade. One for each radio and Ctrl Head. Went to install. LB works the VHF it low beeps and flashes. Found the ground wire off in the 730 at the ctrl head cntr. Put that back on and still does not work. Any suggestions.

PS just pulled a spectra out of my truck dont want to end up having to put back in!!

If the 730 is radio 2 then there is a mod that needs to be done internally to make it power up. You need the KCH-4 instructions. i can email it if you need it. peter.
