28MHz 144MHz WSPR

Image
VK2KRR  sometimes  decoded at 28MHz  even with the low Solar figures

144MHz   many decodes over 648km last days



using WSJT/X  decode   normal seems better for VHF multitraces
quicker and better  decode deep is not good  for VHF
DL3KAV was 150Hz below window  had to tune down for decode
My IC706 checked with GPSDO locked 144.490000
showed center window 144.488500  -25Hz
Not bad for the old IC706
But i have to tune -90Hz  to get DL3KAV in the 200Hz window
