What are you using for a power supply?

I had this happen on an FM transceiver once and found the binding posts 
even though real finger tight were loose.  The transceiver was current 
starved. Tightening up with a wrench solved the trouble.

Have you got a dummy load to use in place of the antenna. A low SWR does 
not always equate to the correct impedance.

Its unlikely it would come from the factory so low on output power. 
Possible a bad final could be the problem though they are pretty good.
