Stefan and Markus;
Good to have you on "from the East side"!  Hoping for a good night with temps here in the low single digits to below zero "F".
Thanks again to Markus for the "short lesson"  very well said and completely digested.  Just doen't seem that such slow keying would show sidebands but it is key carrier and there has to be sidebands and these are put to use.
Thanks an good detections tonight-Bob
