More Chicom: CH-3300H VHF Mobile

At first glance all the Chicom radios seemed to be well known models with just another label sticked to them. When browsing the website once more, I ran into this very interesting 65-Watt VHF mobile, the CH-3300H.

All controls are on the microphone instead of on the box itself. I know from experience that this is very user friendly, and will prevent you from getting too much distracted while driving. Pity it ain’t dual band! No price is mentioned.
