Good signal in here on the car radio just before dawn but with an annoying heterodyne.
AFAIK, they are the only AM broadcaster on 530.
Upon arriving home, went down to the shack and got out the CCrane2E and was able to
separate the whistle from the station by turning the radio. Placed CHLO in the null and peaked
the whistle northwest-southeast of me. Did some quick internet research and there appears to be
a 10 watt TIS in Lansing MI on 530. Based on my quick DF that would make sense.
Unable however to hear any voice from the possible TIS.
