    Transmitter power problem?

    Hello All,

    I am having some trouble trying to get my setup to work. I think it should be simple, and I think the problem is that I'm not getting power to the Tx (but I can't be sure)

    I have the following setup:
    1.3 Ghz 300mW TX: http://www.readymaderc.com/store/ind...cPath=11_30_38

    420 line camera: http://www.readymaderc.com/store/ind...roducts_id=200

    The Tx is connected to camera by a number of connectors (Tx mini cable, audio jumper, video jumper, camera cable - all from ReadyMadeRC)

    I have this setup plugged into a fully charged 1100mAh 3S battery: http://www.readymaderc.com/store/ind...roducts_id=701

    And the receiver is:

    900Mhz-1.3Ghz Rx: http://www.readymaderc.com/store/ind...roducts_id=912

    The TX is supposed to transmit on either 1258Mhz or 1280 Mhz (ch. 1 and 2 respectively) and the Rx covers both of those. When I plug the AV into my TV the TV instantly recognizes it and says "no signal". Then I connect everything up, being very careful that all is red to red, black to black, etc.

    Nothing happens. So, basically I don't know what is wrong, but I suspect it is that the TX isn't powering up. I checked the battery, and it is fully charged.

    Any thoughts? There doesn't appear to be any light to indicated that the Tx or camera are receiving power.

    Here is a photo of everything on the Tx side that is hooked up.

    Okay, an additional piece of info: When i hook the camera directly up to the TV and the power supply, it works like a champ... so I know it's not the camera. I also unplugged the camera and tested each jumper cable with a power meter, and they are getting power.

    So it's go to be the Tx - any thoughts?

    Does the tx ever get warm to the touch? You are correct in that there is no indicator light to determine if it's getting power, but if the tx is running it should get warm.
    Far better is it to dare mighty things, even though checkered by failure; than to take rank with those who neither enjoy much or suffer much, because they live in the gray twilight that knows not victory nor defeat.
