10mW WSPR by G3WKW

My old work colleague (of long ago) Bob G3WKW has been experimentally frequency hopping on WSPR and has achieved remarkable results with 10mW from his Raspberry Pi. He has been hopping 160m to 10m. Note the spot by K9AN on 15m! Not bad at all for 10mW and a stand-alone PC.

Old QSL cards

Clearing the loft today I came across several QSL cards from my first year in Cambridge back in 1971 including this one from Bob G3WKW for a QSO across town using my 1 transistor 2m TX on CW and FM. I cannot recall the details or how I obtained the FM. Power was just a few milliwatts into a dipole in the downstairs room in a terraced house. Bob went on to work for Motorola before retiring in Hampshire a few years ago. We still keep in contact.
