It would appear that the display needs an option to gate the display with the equivent of local TX asserted so it only responds to its own transmitted signal. An option because others might want to know that their TX signal was coming back at them on another coax.
Or perhaps set an adjustable gating power level defaulted to one watt. 73, Guy K2AV On Wednesday, August 12, 2015, Alan <[email protected]> wrote: > The transmit sensor in the P3 TX monitor trips at only a few tenths of a > watt (a few watts with the 2 kW coupler).
