All I have started a test on 137155Khz using FSKCW - 3 mode. I am running 5 watts into the 300Ft perimeter Ashlock style loop. One Loop calculator says that is too short for 2200m, but I am trying anyway. I do see my signal on an online sdr about 130 Miles away. I will switch to WSPR mode after dusk. Reports welcome. -- 73 de N8OOU - Mike Meek
