I'd like to read a hi power Astro Spectra W3 with CPS, but I dont have the Y cable yet. I know there's a way to add a jumper somewhere on the accessory connectors on some Astro Spectras that will allow you to turn the radio on without the head. Is this also possible with the W3 version?
I'm getting kinda antsy and would at least like to read the radio

Thanks!
