That was interesting to see that an AA battery pack is available for the TH-F6A. I've been put off by the proprietary lithium packs of the current Yaesus, and Icom doesn't seem to make a small radio in this class. I'm sort of interested in a small dual bander (2m/440) that can run on AA's. I hadn't really thought about 222mhz and am not sure I care about it. But the TH-F6A is nice and small, unlike earlier tribanders. Does anyone know if the TH-F6A lithium pack is actually repurposed from some other device? For example, the VX-5R pack is apparently the same pack used by some Fuji digicam, so you can get low cost compatible replacements. Also, does using the 4AA pack make the TH-F6A bigger by much?
