Unid. station is WONX 1590
I again heard the station this evening and was able to compare the
broadcast with the live stream from WONX's web site. The station is
WONX in Evanston IL. They were broadcasting an Assyrian language
church service at 2300-0000 UTC, with good signal strength into
WONX's web address is http://www.1590wonx.com/.
