I agree with Don's analysis. Everything looks good around the MAX1406  
transceiver. Since you have -9 volts or so at the output (pin 5), and  
zero on the pin it feeds, there must be something amiss in between.  
The small inductors are easy to break - this might be the problem, as  
could be missing or 'bad' solder joints on either side of the  
inductor or at J1 pin 2 itself. Use a VOM or ZDVM to make sure that  
L2 has continuity (might as well check L3 and L4 at the same time),  
then recheck the solder joints. If the inductor is bad, I'm sure  
Scott will be happy to get you going with a good one...

Good luck!
