JK200SX Posted May 23, 2006 Posted May 23, 2006 Bought one on the weekend to transmit their DVD player to a second set in the house - it is the model that can modulate to Ch 0 or 1. Anyway, prior to connecting all was working ok, connected this in front of the video player and with the power off all is still ok, switched the transformer on on this unit and everything went fuzzy, the worst being channel 2, followed by 7, 9, 10, 28, 31 and 50 & 55 being the modulated satellite receiver and video recorder showing the least disturbance. Anyone know what could possibly be wrong? Would the symptoms described above be due to the powersupply pos/neg wires being swapped over after the transformer? Thanks, Jk
bellotv Posted May 23, 2006 Posted May 23, 2006 VHF modulators do that. When you turn it on (via the power supply) it cuts out all other signals and only outputs Either channel 0/1) Nothing is perfect so instead of cutting out all other channels dead ,you still get some leak through of the others and hench snowy versions to differing degrees depending on their strength to begin with. Remember in (the old days) when VCR's had VHF modulators and you had a TV/VCR switch on them(or the remote) which you would use to watch TV and record another show. If you had a UHF modulator this would not happen as they GENERALLY pass all signals and add modulated signal to it.
