thanks! its great news that the internal antenna is better than the
external one. the bad news is that i am trying to use the loop because
the am reception on that radio is so lousy! i have 3 dx390 radios and
the am was lousy on all three. my dx39/ats606 runs circles around all
the dx390/ats818 radios yet it responds well to the loop. hmmm. i guess
i should check into alignment procedures.
