Hartmut;
You make it look easy!!! 
That station on 74.548 is WG2XRS/5, Dex in South Carolina.  I am sure you will see him when condx favor his area.
Really great capture-this time I have my transmitter running correctly.  I thought I better drop down .1 hz as I was seeing sigs on .550 and .549 on Vester's grabber but then remembered you have directional ant and the sigs come from east of you and are not a problem.  I can go to 74.549 from now on.
Thanks for all your good work! Bob  WG2XRS/4 NY
