Having read the article in the latest Radcom re 70mW of WSPR for the Queen’s Jubilee, out of interest I ran 70mW ERP on 7 MHz overnight.

I was spotted by 133 different stations, the furthest being several reports from the Canary Islands at just under 3000kms.

Antenna is a 7MHz EFHW about 2m above ground.

Quite pleasantly surprised how far such a small amount of RF can get, even recognising the ability of WSPR decoding.
