I have had the 989C in service for about 6 months and have had the
following 2 problems:The transmit cap became loose and would flop over. It
was disconcerting at inconvenient times.
The avg/peak switch arrived wired backwards.
Both of these were fixed easily by me.
I have never run more than 700 watts on it on CW, so I can't speak to it's
capability to
handle more. The built in dummy load gets very hot near its rated
continuos power.
It does seem a tad 'inexpensively' made, but I knew that about MFJ
equipment when I started.
