IIRC, the first radios to hit the store shelves became available around October 18, 2007. I'm not sure what the initial serial numbers would be or the date codes, but my radio's serial number is in the 1500 range, and the date code is 10A07.Does anyone know the exact release date when the psr-500 handheld was released? Wondering what the first production date codes and or serial numbers would be....Thanks
Finally up and running.Mine should up in a few days. I'll post the seriel # and date code.
