== Distinguish 30w from 100w model ==The 100 watt model has the amp stage in place of the rear heat sink and is much larger. This appears as a large box on the rear with large heat sink fins. Early Ranges used a 4-pin microphone jack that was compatible with 4-pin Cobra CB radio microphones. Clear channel then switched to an 8-pin microphone jack with microphone that offered up and down buttons for channel change. An 8-pin mic doesn't mean that it will scan. The scanning board was an extra add-on. == Optional Addons ==There were some optional add-on boards available for the Clear Channel Ranger AR3500.* Frequency scanning board* SP-1 speech processor board* CW-1 variable RF power board
