    I have a 7300 which works fine, but could use a little help in noise rejection (Local Power Lines). I've just purchased an MFJ 1026 to help in that area. My question has several part.

    I'm assuming that the T/R relay in my 7300 simply pulls the T/R line to ground, thereby indicating the transmit function is happening. All other equipment sees the ground and behaves as needed. Then the T/R signal is not grounded, everything assumes we are in the receive mod and behaves accordingly.

    Is there a limited to the number of circuits that can be connected to the 7300's T/R connector ?

    I believe the 1026 has a T/R delay function. If so, how should this be adjusted ?

    Thanks for any help what so ever.

    Regards,
