I just finished SN 5319 a few days ago and all is working perfectly except that 
the output power fluctuates. The radio is stock with no options. It will not 
fluctuate while the radio is transmitting a solid carrier, but as soon as you 
unkey and start sending a carrier again, the power will drop or jump several 
watts.  It is as if the power control was changed but it was not. It does it on 
all bands. It does it into a dummy load or an antenna. The current limiter has 
been ruled out because it is set for 3.5 and the current is not exceeding 3.0. 
There is not voltage drop on the power supply so I also ruled out a power 
supply issue. it is just as if the ALC is kicking in and turning down the power 
randomly. When the output power drops, the current also drops accordingly.

The radio seems to work perfectly otherwise.

Your suggestions are greatly appreciated.
