1424 - I can barely detect a signal there. It's up and down and most of the time does not even show up in the display. Evenn though I often park on 6925, I probably wouldn't have been aware of the signal had it not been for the post by Chris. Thanks!
1428 - brief CW that caught me off guard but I did catch "... CODE RADIO"
{edit}
1438 - more CW. I picked out what seems to be "PRE CODE FILM EE 4 HOURS" repeated 2X
