So.. during a WSPR 10mW/-21dB, 10W might get +6dB SSB.<br /><br />(A while back I gave John my own code that cycles through the Si5351's power settings. Using that, I've managed a 2mW ping on 40 metres with a Chris VK2CJBhttps://www.blogger.com/profile/15300497329805705585noreply@blogger.comtag:blogger.com,1999:blog-35901825.post-88853543748768527332020-05-21T10:54:23.117+10:002020-05-21T10:54:23.117+10:00Thanks Jules, that's a great reference.Thanks Jules, that's a great reference.

...Hi Peter,<br />https://www.qsl.net/kp4md/wsprmodes.htm<br />contains some interesting comparisons of WSPR vs other modes.<br /><br />Don't forget the VK2RWI CW beacon on 3699 is a good Sydney beacon.<br />VK3ASE is over 59+20dB on AM into Sydney tonight on 3670!<br /><br />Hope the move went well and you're re-acclimatizing to those cooler temps! <br />- Jules VK2EXTAnonymoushttps://www.blogger.com/profile/16664486887117418685noreply@blogger.com
