I just got my ham license and am currently researching mobile rigs myself. I wanted an Icom IC-706 to just do absolutely everything, but it seems like a 2 meter would really be sufficient around here. Kenwood also has a few mobiles, as does Alinco. Wouxun is the only other brand I'm aware of outside of specialty base station equipment, but I think they only make HTs so far (been hearing a lot of chatter about them in my week on the air so far). The biggest two bands in north Georgia seem to be 2m and 70cm, so I'll probably get a dual band rig for starters. Honestly I've spent more time pondering an antenna setup than the radio itself - just don't have a way to go about 3 feet (MAYBE 3 1/2) for an antenna and make it into my garage OK. Once you get into all-band radios the antenna situation becomes way too complicated, seems like a dual bander is about as crazy as you want to get unless you don't mind a big honkin' antenna. Not looking for anything fancy as far as APRS, DSTAR, etc, since I don't really understand all the things you can do with options like that yet and they seem to as much as double the price of a radio.
If the radio is only going to be used when you just use the Jeep, I would stick with just a 2m radio. Most 2m radios are approx. $200. If you plan on going any farther with the hobby I would get a dula band radio (2m/70cm). Dual band radios are $300+. I personally have the Yaesu FT-8800. That is a dual band radio. Here is a link to my radio install.
Why do they put the buttons on the mic? Looks like a major pain to do things. Have to use 2 hands? One to hold the mic and another to program it?
Seems a lot easier to push a button or turn a knob when the button or knob is mounted on the radio.
the buttons are for direct freq input to the radio, programming the radio or for sending DTMF tones. programming through the keypad isnt that difficult as long as you read the instruction manual. the radio will also have a dial(VFO) to change the freq or change the ch if they are programmed.
