Our local club has bought and installed three Fusion repeaters - two on 2
and 1 on 440.  There are perhaps a half dozen Dstar repeaters around Chicago
and I am told two small coverage DMR systems out at the edge of the Chicago
land area.  So it's buy three transceivers or wait for the dust to settle!
I'm waiting for the dust!
