I'm rigging my Tacoma pick up as a chase vehicle for the Mexican 1000 race. I need a dual band radio that can be modded for extended frequency Tx. 150-158 Mhz is used during the race. This is legal and widely used in Mexico for this race. A small form factor and the ability to monitor 2 freqs is also desirable. APRS is not used but I suppose l might as well have it. The antenna will be mounted on a bracket bolted to the hood hinge in front of the drivers A pillar. I want 2 antennas. One for everyday use and a long one for use during the race. I have access to an antenna analyzer so tuning the antenna is not an problem as the antenna will only be changed out a couple of times a year. Thanx for any insight.
