4m QRP success - 229km today in the contest

Using my small 1W QRP 4m transverter recently built into my loft dipole I've just managed a QSO with G4RFR 229km away in Dorset (IO90AS) using CW in the RSGB Cumulative contest. He was on SSB and it was hard work, but in the end a full exchange was made.  Also heard G3EDD, G4ASR, G3BCU, G3TCT, G4DEZ, G1EHF on the band on SSB and G4ZTR on CW.
