He seemed to have a big pile up of DL stations calling him, this did not seem to be the case this time. Possibly there is some discrepancy in calculating the powers required for the ERP from the two antennas, or in measuring them. The small antenna was putting out the sort of signal I would have expected from such a station, and was fairly similar to both Jim's home signal and Mike G3XDV who is not far away. I would have expected the Puckeridge mast to be rather stronger, certainly G3LNP in Tring who claims to run 1W erp is at least 25 over s9. Thankyou Jim for organising this weekend's activity. I did call on several occasions but it seemed you were not hearing me - strange! Cheers Dave dsergeant@iee.org http://ourworld.compuserve.com/homepages/sergeantd
