We ask that participants keep the initial contact to "This is ...... , Danie do you copy?
Between 0200 and 0300Z, visit http://wsprnet.org/drupal/wsprnet/map and enter ZS3D in the call sign box. Zoom the map to your part of the world and look for WSPR transmitters that Danie is hearing located near you. Then go to http://wsprnet.org/drupal/wsprnet/spots and enter the callsign of the station near you in the "Call" box and ZS3D in the "Reporter" box. Over time you can generate a correlation between how Danie reports this WSPR station with how he can hear you on SSB. Your SSB power and the power of the WSPR transmitter will influence the results. For me in Southern California, Larry, W6LVP who authored this advice, found that a WSPR SNR report for his 5 watt transmitter from Danie of -17 or better is necessary to establish a Q5 SSB contact running about 900 watts. Your individual mileage may vary. There are four WSPR transmitters dedicated to support this initiative: K4APC in Atlanta, K5KWG in East Texas, W5GHU/7 in Southern Arizona, and W6LVP in Southern California. .
