I left ARGO running overnite but was not able to see a trace of 'SL' here in SC. It looked like 'XES' abruptly turned on sometime around 3AM and turned off again around 4AM using DFCW. XES dots on 137.779.0 and dashes on 137.779.2 KHz Here is an address to a screen shot : http://imagehost.vendio.com/a/32051022/view/ARGO-D00001.jpg 73 - Todd WD4NGG
