So, for now, I've gone back to the earth electrode antenna and changed frequency to around *137.675kHz* in the QRSS segment. Realistically, until I radically improve the antenna system and increase the power another 10dB, I don't expect to get reports beyond about 20km. However, if you're relatively local to JO02dg (Burwell, East Cambs) please take a look and see if you can copy me.
