Baseline HD was the first RTK base station Outback Guidance had. It had a 10 channel MaxStream Radio in it. The BaselineX came later and had the 100 channel Microhard Radio. Neither are repairable by Outback Guidance. If you sent it to someone else, could you tell me who it is? I may need that info in case someone else needs to have their Baseline repaired. I'd really appreciate it.
