If QRN levels can be overcome propagation conditions on the MF AM broadcast band, 160 meters and 120 meters should be good tonight UTC Saturday-Sunday October 02-03, 1004. 73, Thomas F. Giella, KN4LF
Pete et all, I know that MF propagation conditions will be good tonight because I've been accurately forecasting MF radio propagation conditions for 31 years. I don't have time to explain now because
I have updated the instructions for installing and configuring, then operating, the MS-PSK PropNET software on 10 meters (28.131 USB). If you are interested in joining our research group, please visi

Hello group, First time posting. I am looking at these maps and reading the instructions and I am still in the dark as to how to use them. I will tell you first what I believe is the way to use them
The 'critical frequency' is the highest frequency that gets reflected when it is aimed straight up at the ionosphere. So it is a measure of the electron density above a particular location. It is not
Art, I have referred to the maps as well. Over the past several years, I have found the numbered contours to be a reasonable indicator of propagation. 40m is open most all of the time beyond the firs

yes you never know where a band will be open to when it sounds dead. last month i turned around on six at 21:30 est here in Ky. did not hear one beacon. so i just sent a ? and my call on 51.250 and w
