VHF in a suticase. These are great ideas for any quick response team. The higher power available from the 'base/mobile' radios will give greater range than a simple handy talkie.

Portable unit made from an old PC case houses several radios and a cellphone. A gel-cel and charger is built into the bottom of the case. It weighs about 20 lbs.

From top to bottom, 440-MHz ham, 2-meter MHz ham, CB, and FRS. Note the FRS 'emergency boost' switch.. ahem..
This view shows how the connectors are arranged. It looks like the PC power supply has been kept, but I would think that it's only the chassis for the bulkhead power connector. (The usual PC supply can provide a reasonable amount of 12VDC power, but the voltage is not high enough to keep a gel-cel charged properly. Additionally, most pc power supplies require a minimum load in order to not shut down. usually a 5 amp load on the 5V output is sufficient, but that wastes 25 watts and makes alot of heat.)
