Please try out our 444.45 MHz machine. The work party Karl Joe, and Matt did some testing why the range didnt improve with the antenna being in a much higher and they found out some interesting thing. First in an undocumented item is that the repeater has a lot more power when running under AC power vs DC power. The biggest issue they found was the old grey antenna duplexes was destroying our receive and it hurt our transmit too. They swap to the Chinese Duplexes and wow it immediately improve the range.
The above map is showing the current RELIABLE range circle where it reaches down into the valleys and working inside some homes with a simple HT. It will reach outside the circle but it seem to work station that are located on top of hills. Please give Karl or Christine your signal reports let us know your location and power level. We are planning to get the old grey cans fixed since they can handle a lot more power. The Chinese can are at there max power now.
