There’s a guy who does forecasts at <a href="http://www.dxinfocentre.com/tropo.html">http://www.dxinfocentre.com/tropo.html</a> although they’re more east coast oriented. Here in Toronto during late summer tropo season people sometimes pick up faraway stations from Pennsylvania or even Ohio which is beyond deep fringe.<div><br></div><div>So, the trouble you’re having might not be your setup, it could be a faraway station booming in and interfering with your local one. Or not. In any case I also find that HDHRs, particularly the early models, have not the best tuners especially when compared to a decent quality television.</div><div><br></div><div>- George</div></body></html>
