I do hope a new version is produced in due course. Maybe the next edition will include something about WSPR and how effective results may be achieved, on 500kHz at least, with a *totally* simple station set-up like my own running just microwatts ERP. The only error/confusion I spotted is on p81 (of the 1st edition) when it talks about current transformers. There is something screwy here when working out the current in the secondary. 73s Roger G3XBM ------------------------------------------------------------- http://g3xbm-qrp.blogspot.com/ http://www.g3xbm.co.uk G3XBM GQRP 1678 ISWL G11088 --0015175dd9c6fd7cd604776887d5 Content-Type: text/html; charset=ISO-8859-1 Content-Transfer-Encoding: quoted-printable Mike (et al),
