Actually, I would prefer the parn/neutral safety switch, as the door could be opened then closed to spit or something, and the VRS would be activated.

RE: [Repeater-Builder] Re: what pac-rt means
George-I will let the Motorola guys on here answer most of your questions, I tend to stay on the GE side of things, however, the HT does not become a repeater when placed in the cradle, but a simple HT turned into a mobile, The HT's generally had a single channel in them, with PL, not sure about that one, the switch I believe you will find was supposed to enable and disable the PAC-RT that was attached to a different mobile radio mounted in the trunk and with a control head up front, therefore the combination you have should work as an HT and also as a mobile with amp but not as a repeater.

RE: [Repeater-Builder] Re: what pac-rt means
Correct—David and it DID work ONLY when they keep their radios in the charger—on the CA CHP system if you listen on 154.905 you will clearly hear the beep as they exit their car—it is also a great way of keeping track of CHP cars which are close to you since all of the traffic they receive on their low-band radios is rebroadcast on the 154.905 channel if they do not have their portable in the charger and most don’t.

Re: [Repeater-Builder] Re: what pac-rt means
How did the units know when the officers left the scene? By them putting the HT back in the charger I assume? Pretty smart plan, actually. Neat. I take it if they forgot or tossed it on the seat when taking off, they could be cut off from comm until they stuffed it back in the charger, or was there a really long failsafe timer that would turn the micro-repeater back on? I guess there probably couldn't be... or some day long event with multiple units, would certainly have the repeater's re-enabling themselves...? -- Nate Duehr n...@natetech.com On Fri, 23 Oct 2009 13:28 -0500, dmur...@verizon.net wrote: Had a problem with the PAC-RTs when I worked in Virginia for the State Police.
