Hi Stefan, Markus and Group, Thanks for looking Stefan. The ERP was down until the second Decca module was switched in at 2330 bringing the output power from 150 to 450 watts (3.2 amps to the aerial.

Dear Group, QRV again tonight. QRSS30 and seeking comments (especially unfavourable ones) on accuracy, drift and keying coherence. Vern's grabber is capturing them well at the moment. Thanks again, V

Hi Joe, looks like carrier stability was good while the signal was weak, but deteriorated after 2 UT. DDS affected by QRO? Best 73, Markus (DF6NM) From: [email protected] Sent: Thursday, June 06, 2013 1:

Hello Joe, Sorry, can't see you here. Nothing at DF6NM too... Is your ERP on the usual level? I remember our QSOs in QRSS-3... Good luck anyway! Maybe you will have chances in Venezuela: http://dl.dr

Hi Gary, Thank-you for the report, caputure and for running your FB grabber. I look for sigs on your grabber quite frequently to check the TX. The TX will be on again tonight, (without chirps I hope)

Markus, Thank-you for mentioning this problem. If it's QRO -> DDS it's likely due to shoddy construction technique by the operator! When this has been dealt with, we can try some OP32. 73 Joe Hi Joe,
