Hi Andrew,

	My problem is restricted to 15M SSB and does not seem to be
related to how long the rig has been on. 
	
	When I tx on CW either direct or through the tuner the SWR is less
than 1.5 to 1 but when I switch to SSB (again either direct or through the
tuner) on the same frequency the SWR shoots up to greater than 3 to 1,
the HI SWR light comes on and the rig stops tranmitting.  As with you the
antenna system has been well tested on other rigs. 

	This problem is well beyond my understanding and I'd be most
grateful to get some understanding and, especially, a fix.
