This page is dedicated to the resources I have for the Motorola GM350. It is used both as a standard mobile transceiver, as well as a link for voip internet / radio links. In this regard possibly the 128 channel version is better than the 4channel one as the former seems to have all aspects or attributes available via the outlet data connector. If I am wrong then please do let me know, and I will update the information according to any feedback I get to g3vfp@blueyonder.co.uk
