I had WSPRLite in a box for over a few months, almost forgotten. Yesterday I activate this tiny TX for WSPR. Now I didn’t need my pc, I don’t need software, I have less power consumption. I can run it for max 30 days.
With DXporer I can see my reports, can make a comparison with a radio amateur with e.g. the same power level. Now after one day I was surprised that 20 meter was open late in the evening between 23 hour and 0:00 hour. I was spotted by several stations in the USA with my 200 mW.
I like WSPR as a tool for propagation research. Now I use 200 mW (max power) but I can go lower to 5 mW. That will be nice when the sun cycle is at the top again.
