About a month ago, I bought one of the older model Vertex/Yaesu VX-150 hand-held transceivers. I've used it for approximately three weeks, for about a half-hour per day on the charge that was on the battery when I bought it.
Yeah, I don't talk much but I'm still amazed by any device that lasts that long on a single charge. Only today did it start acting up because of low charge.
About the only thing that I want to change on the radio is the antenna. The stock rubber duck antenna requires that I jack the transmit power to high (~5W) so that I can reach the local repeater.
