Overall, I like my new GW-M5610R-1, but I've had it for a week so far, and it's never synced. The last time it synced was when it was in Japan.
Given that I've had 3 other waveceptors that all worked, and that I've attempted to sync this one in the same manner and places, I can conclude after a week that it is indeed broken. I guess the antenna works in Japan, but not for the US signal. Home city is set correct.
Unfortunately, since I purchased this one on eBay from Japan, it's not going to be worthwhile to try to return. So I'll just have to take the loss.
Anyone else out there have broken waveceptor stories?
