That was my first radio ! It was just umbelievable how was possible to have so nice dx with just low power ... few months later, I got my first Kenwood 100watt ouput, and soon I forgot the possibility of low power ...
Then recently I bought for fun a kit: the SW20+ from Small Wonder Labs, a little QRP CW TRANSCEIVER ... a real low power, just 2.5 watt !
After building the kit, started to send some CW, and the first time that I try to reply to somebody, immediately I got the reply ! The surprise was twice, when I heard the full call .. A45XR !! Umbelievable ! Just 2.5 watt and a GP 1/4 fo 20 meter just hang on the garden ... This is the "power" of low power !!
During my holiday in my Summer House in Sardinia, I got a lot of contact from USA with my little QRP ! So fun !
Here below some picture from a recently short activity from San Bernardino Pass, about 2000mt. high !! Very cold, but lot of fun !!
