"以前" 的 portable tracker
the insides include a 12vdc rechargeable gel cell battery, an htx-202 2m handheld radio, and a paccomm handipacket tnc. on the outside are the tripmate gps, and antenna. i also mounted a power meter and dpdt switch, to change between internal and external power. the meter is checked by depressing a small momentary switch which you can't see in the picture. the main power switch turns the equipment on using either internal or external. there is no need for access to the inside components once the tracker is configured
沒有車, 我想帶不到了 - 那就是當年我想也不想玩 aprs 的原因!
