[Facing problem with two X-10 Transceivers]

I'm implementing X10 on 240V, 50Hz power line. PIC16F877A microp is used to generate 100kHz X10 signals. Proteus 7 is used to simulate my result.

My transceiver circuit is as shown in the attach Transceiver.jpg

This is the output i got when the transceiver send and receive on its own.
(as shown in 1Transceiver.jpg)
Yellow - 240V power line, Blue - 100kHz X10 signal from XOUT, Red - Received Signal at XIN

I face problem when i try to send and receive using 2 different transceiver where TranscA is to send and TranscB is to receive. But what i got is as shown in 2Transceiver.jpg

Where have i gone wrong? Will it be:

• My Tuned Amplifier Circuit?
• PWM?
• or which other part?
