Got it working Bruce with a non-inverting buffer.

One thing is for sure...the Linx ES rcvr is not compatible going straight to the Pic (PortA4 anyway).

Now, I'm having a bit of a problem with data out of sequence between xmtr and rcvr but just a "timing" thing.

I may be able to live with it but I'd like to solve that as well....without rewriting the PIC software.

Using SERIN and SEROUT at just 1200 baud with 2 qualifier bytes and the data byte.

Are sequence problems just part of the "RF deal"?
