JR Help!!!
It is certainly a good system in its day, but it has been surpassed and it is not made any longer. It is capable of ZPCM and PPM, so it doesn't use the current SPCM receivers. It uses the same RF modules as the current 8103's and 10X systems, and we can service the PCM 10 and check them out. There are no updates available however. It has some limitations when compared to current systems, but it is still a good radio.
