I have received my Custom RMRC FPV Package - 2.3-2.4 GHz with the 700mw tx and sky hammer rx antenna
I can only get signal on the ground with both rx and tx set to channel one, but I'm only getting about a 50m range.
I have tried other combinations of channels but getting nothing.
I am assuming channel d at 2305mhz should be best with the tuned antennas but getting nothing

Any ideas?
