TW523 transmit problem

["Bob" <bobnospam1@xxxxxxxxxxxx>]

I have a homebrew home control system that uses a TW523 X10 transceiver to
receive commands from X10 control boxes and send X10 commands to various
devices. The TW523 recently stopped transmitting commands over the
powerline. The LED on it blinks when it tries to transmit, but X10 devices
receive nothing. It receives commands fine. If anyone has experienced this
problem, especially if you have solved it, I'd love to hear from you. Web
site references would be helpful if you've seen anything related to this.

I've fixed several RF modules in the past, and hope this might be something
easily fixed also, as I am on a tight budget these days..
