Prior to my moving to my current location Central Valley of Calif. (mid 90's) I was part of a group that met on 432.100 regularly. My current location restricts my ability to have towers and antennas for every band, (now only a couple of well concealed vertical antennas), so I haven't been active on 432 ssb since. I do know that several of the hams that I used to chat with regularly on ssb are still active there, but not like it was in the late 70's thru early 90's when there was group activity on a daily basis.
