You can do that with an Alpha 89, 87A or 91b (soon to be 99.)
In trying to find more info on the LK-550ZC, I searched the QST CD-ROMs and
came across a whole bunch of Alpha ads from 1988-1989. Remember the 86? And
there was actually a picture of the 87, which I think was replaced by the
87A before being released. The best were the original 89 ads, with the
"brick-on-the-key" contest. I'd forgotten about that!
