472kHz - getting started

I have had a great deal of fun on 472kHz even with a very low ERP (10mW ERP). Most nights I run my shack PC on batteries as the SMPSU charging the laptop battery produces an S7 noise floor. Most nights I am spotted in Norway on WSPR. On RX, the PC is good for most of the night on batteries. I use my simple 472kHz transverter (10-15W into 50 ohms) that has been in QST and the RSGB book "LF Today". It is a very interesting band even if your antennas are, like mine, really useless for MF. Compromise antennas really do work!
