If you're using Trimble radios the radio will flash "Busy" instead of "Transmit" if youve got other traffic on your frequency. Just switch to another frequency. I've rarely run into that problem. Usually it was a low battery that caused radio problems.
Related question...I have a Trimmark 3 radio, it is narrowbanded. I have only used it a few times, but had a recent need to use it. I found that I could not get it to work if I set the base and rover to CMRx. The radios are set to trimtalk V1 9600. Both CMR+ and RTCM3 work fine.?ÿ
My understanding (admittedly limited) is that the broadcast protocol (CMR+, RTCM, CMRx) should be invisible (i.e. not matter) to the radio. The rover decodes and displays the reference number from the base (so it does get the signal), but then times out "waiting for information from the base".?ÿ CMRx works over cellular but not over the radio. R10 base and R10/R8 as rovers.?ÿ
I run my R8.3's through the internal antenna quit often with great results. As you know its broadcasts strength is 2 watts so don't expect anymore than 1/2- mile on a clear path. I have frequently been around quarter sections with no issues but also been 1300' away and down a valley and have issues.
Everyone has given really helpful insights, I just wanted to second the idea of getting your antenna up high.?ÿ I have a set up with a 25' radio cable that I screw into the R8, then it goes to a quarter wave antenna on top of a 15' pole.?ÿ I can make the pole taller, but we have wind almost always, and taller gets unstable.?ÿ I have a 2nd antenna cable I carry with a 2nd antenna, and if I find myself still not receiving radio, I can run that antenna up (I carry an extendable range pole in the truck for this) and I have been successful getting radio in canyons, over hills, and at some pretty long distances.
The R8.3 internal radio are 2 watt.
I don’t believe they came in any other option but the 2 watt.
