I have a Topcon GR 3 which has been set up as a Rover. Recently I have noticed that the Radio Link has been having poor performance. I ran a check with a GR 5 at the same distance to base of about 1,765' to base and the results were as follows: GR 3 Radio Link = RTCM3.x age= 15s, 46% GR 5 Radio Link = RTCM3.x age 1s, 100% We are use to seeing the link go from 97-98 to 100% normally. However, this is now creating a problem. The GR 3 seems to work fine as a base which would mean the problem would be with the receiver and not the transmitter. Any help would be greatly appreciated.
