Scratch that, a later version of the data sheet does show an electrolytic cap in series, but no value is given. I would say that is is not necessary if you don't have any DC on your mic line. A small value electrolytic should work, somewhere between 10 and 47 uF probably. If you really want to know, I could dig out my 444D later and see if it has the cap. 73 -Jim -- Ham Radio NU0C Lincoln, Nebraska, U.S.S.A.
