We do not have mobiles in the truck. We did come across several vehicle chargers that have the VRS switch to turn on repeater remote from charger base. Or it could always be on when vehicle is running either way works.
Yes we do have the license for repeaters, mobiles and handhelds nationwide.
The VRS switch on the mobile charger is use to activate an external mobile extender.
There's a couple of things to look at:
You can use XTVA's which will allow you to dock the radio in a vehicle. The dock will power/charge the radio and allow a connection to an external antenna. speaker and microphone. The connection to the external antenna will greatly improve performance.
Other option is a mobile repeater/mobile extender. This is a small radio that gets interfaced to a mobile radio. The hand held radio transmits into the mobile repeater (Look at Pyramid brand, or the Motorola VRS) and that passes audio between the mobile radio and extends range. Setting these up isn't easy and takes some engineering and proper licensing (licensing can be different that the 'repeater' licenses you may have). This is REALLY a place where you need a professional to design, install, and align the setup. It's not 'plug-n-play' and you can't buy parts off e-bay and just plug them together.
There are also bluetooth mobile mics that would give you a few hundred foot range around the vehicle. The blue tooth mic interfaces to a mobile radio and gives you some range.
You can do an itinerant repeater setup, but you must have that specifically listed in your FCC license. This can be a portable repeater set up on site, or something permanently mounted in a vehicle. Mobile/transportable repeaters need to be designed for rough use, most components won't like getting bounced around in a truck all the time. Again, not really an "off the shelf" solution and not a 'plug-n-play type thing you can assemble from parts and expect to work well. A basic portable repeater set up is a good option, but it won't be cheap. If that's something you are interested in, there's some good options out there.
