    2=A2  . I am also have been using a 386  with success. What I am doin=

different is I am using a Radio Shack  atomic clock. It runs $30-40 but i=
t does
indicate when one has an acceptable signal level. It comes with a "dog bo=

antenna. I lengthened the cable to the clock though.  I positioned the an=

at the other end of the house (~40') from the clock and still have an acc=
eptable
signal level and no problem locking.
