[AMRadio] Hash on 3710

Friday night was a good night for Pacific Northwest AMing also.  We had a 
group on  3880 during the evening that included
northern California, Oregon, Washington, Idaho and British Columbia.  The 
roundtable went on for quite some time.  I must say
I was very proud of my Viking II and the 100 watts into the inverted vee. 
The old girl worked very well.
