My views on WSPR are simple.=
  • It is (will be) enormously helpful when analysing LF antennas/= station improvements.
  • It is very useful for indicating propagation changes and on highe= r bands like 10/6m can show openings that might otherwise be missed. I hav= e already seen 10m signals at 3am for example.
  • It allows QRPp= signals like mine to be detected on LF, HF and VHF bands, although I agre= e other weak signal modes may be as good (but may lack the internet databa= se feedback element which is the REAL killer application for me).
  • The on-line database is very helpful in getting almost real time= feedback and indications of your station's coverage.
  • It= is not a replacement for QSO modes, but is an extremely powerful beaconin= g tool.
BTW, I hope to start on my improvements to my basic 500kHz station= in the next few weeks so would appreciate 500kHz WSPR reports again once= my signal reappears. Once my signal gets to a decent level I am looki= ng forward to some CW contacts as well.
