Rik, &=20 Andy,

 

Thanks for your=20 report & comments & Andy for answering Rik's=20 query.

 

Well there has not=20 been any response to my CQ call so I will change the text to beacon= &=20 continue to see if there is a report from further=20 afield.

 

If you want to try=20 for a weak decode I can reduce the power for a short period say 30= minutes, my=20 power is 50 watt RF (200 mW ERP) at the moment so in view of your go= od report=20 I could take it down to 10 watts RF.

 

Let me=20 know.
