Perhaps you should set up Linrad for "normal CW" if you use it on 
microwave bands. You may set the bandwidth to 60 or 120Hz and you
should definitely make the second fft bin width compatible to the
bandwidth of the signals to get optimum AFC operation. What you
should get from the loudspeaker should then be identical to what
you get from the FT1000, just a bit more convenient because you will
not have to tune now and then to follow the frequency drift.

I guess there is no need for a blanker on microwaves so you might 
save some processing delay by disabling the second fft.
