Power Line Transformer

powerline transformer diagram

I want to do communication on 220VAC, so I am need of Power Line Transformer PLT, I am not able to find it over here in my local market. I have FSK signal which I want to send on 220V AC. I came across some transformer spec, they include 50Hz blocking capacitor for 220V that's the high pass filter. It blocks the 50hz frequency and lower one too. My FSK signal is around 1070Hz for Space and 1270Hz for Mark.
I was thinking if I could make Home Made Transformer is that possible?

As an example, this is the transformer



I am worried about one more thing as given in block diagram of transformer, it has a Data Processing Chip, Line Driver, AFE, DFE.
Is this worried, for the X10 communication and other articles given in internet about Power line communication, I think transformer is very necessary for this, but I can not get one for me, I need it for FSK, I hope to make a custom home made Transformer. As the above mention transformer has 50Hz blocking capacitor built in. I have to attach one in series.

I don't think, that around 1 kHz carrier is a suitable frequency for power line communication, at least for the short range. These frequencies are used for long range (grid wide) controlling purposes by the supply companies. Cause the grid impedance is rather low at these frequencies, high driver power is required. On the other hand, the noise background from none sine loads is high.

Most short range power line communications is utilizing the 100 kHz to several MHz range. Interferences are attenuated by power line and meter inductances, only in-house interference sources have to be considered in most cases.

you can find the data communication over power line project in elektro book series
302 , etc.

but they are using am modulation over pl, i am not conform about book number ,but this topic is there bcoz , early i need such project to control home appliances , i left that one and use rf for controlling .

any way good luck !
