When I turn on my Texas Star DX250HDV the receive on my RCI 2950DX seems to go down. Any help would be greatly appreciated.

Does it go down when you turn on the RX Amp? If so you need to replace the 2 small transistors , there are only two , 2N2907 or 2N3904 should be the numbers. If the numbers are different , still change them. Depending on the build , they change. One is the keying transistor the other is the RX pre-amp..Change them both and let me know.

It goes down when I turn on the amp. The receive amp doesn't even work. It was working fine up until a few days ago.
