Long distqance shortwave signals are only able to be picked up so far from the broadcaster because the "sky-wave" signal is bounced off the upper parts of the atmosphere. The reflecting properties are badly affected by ionisation caused by sunlight and especially sunspot activity. What this means is that your best listening times are when the broadcaster and the receiver are both in darkness. Expect best reception from about 2 hours after last light to about 2 hours before first light. Try your local public library for books on SWL and radio theory.<br><br>Happy listening!
