Batboard

I know, drag out the dead horse...but my issue is a little different.

According to the rear accessory connector diagram for the spectra ( http://www.batlabs.com/images/lmda457.gif ) , it mentions "4"- "Functional only in dash mount configuration, N.C. in remote mount configuration"

I have a older mid-power VHF Spectra W5 with a remote mount and it works fine without that ignition wire.
I just received two mid-power VHF ASTRO W7's that are dash mounts and require +12V on pin 5 to power up.

I have checked here and repeater builder that describe the jumper settings to disable the ignition sense. The two W7's I have, HAVE the jumpers set to ignore the ignition sense and should power up, but they don't without that darn +12V on pin 5.

*IF* a remote mount configuration bypasses the use of the ignition sense as referenced above, is there a way to 'trick' the radio into thinking it has a remote head on it when it doesn't??

Dash mount radios have to have the IGN, small red, lead on the 15 pin Accy connector connected to power up. Fuse this at 1 amp to be safe.

Been awhile...but I believe there are also CPS settings for the ignition power up settings (as in enable/disable/ptt inhibit etc). Might want to take a look at that as well.

Jumpers where? If you jumper the control head it should power on with no ignition sense regardless of it being dash-mount or remote-mount. You might still need to energize the green wire on the remote cable, though.

The CPS (and RSS) setting offers you TX Inhibit, PTT TX Inhibit and Blank which is normal operation.. no help there.
