Hello: I just purchased the two items (separately) in order to create a FPV setup that would not interfere with my 5.8ghz transmitter. I also purchased an inexpensive monitor. I hooked up all the items correctly, checked my connections, and keep getting a "NO SIGNAL" message on my display. The transmitter gets warm, so I know that the connections are correct. I have set both units to Channel 8 (2510) and even run the receiver through all 8 channels, but no luck. I have also hooked up a small camera directly and the monitor works correctly. I measured the voltage coming out of the camera's yellow connector and it measures 0.75v. I get the same reading from the receiver. At a minimum I think I should be receiving snow. The packaging read TS321, 2.4ghz. On the transmitter the antenna has a sticker that says 2.4ghz. On the transmitter itself there is a small sticker on the metal cover that reads TS351 5.8ghz. The two units do look identical. I contacted the seller to see if any other customers had difficulties and they had no clue. Is there a way to test the signal frequency coming from one of these transmitters?
