  • If your not using an external base radio such as a Topcon TRL-35 or PacCrest 35W radio the Hiper Ga internal 1W radio is only reliable to a range of about a mile (OK Topcon will say 3.5 -5 miles with an * attached ... under "optimal conditions"). 1 mile equals about 1.6 KM (according to my superior Google querying skills). At 1.2 Km you are probably pushing the limits of your Hiper Ga. It all really depends on your radio line of sight...mountainous terrain, buildings, pits wil limit radio reception. I would highly recommend hooking up an external radio to that Hiper... Take a look at a radio made by Pacific Crest called the ADL, http://www.pacificcrest.com/products.php?page=adlvantagepro. This radio could easily get you 20 kilometers or more depending on topography. I have a very trustworthy source confirming this.

    Pacific Crest products provide best-in-class solutions with a wide range of radio and GNSS solutions.
  • Thanx Randy....

  • Our Hiper Pros were 'throttled' back to a short range by a firmware setting; once our tech changed the setting in the receivers, our range improved dramatically.
