Hi Don et al, Just an example: Late last night I made a brief CQ DX and got a prompt answer from Jeff, in TZ4 (Mali) Nobody else to be heard on 160. Let us see if the upcoming Stew Perry will bring some more 160 activity. 73 Len SM7BIC

For the past 11 months I have been running a daily early morning experiment on 160 meters CW trying to copy a specific station in South America running 500 watts (4700 mile path, 160 degree bearing from my location), and I'm able to copy him more than approximately 95% of the days which I would have previously said was impossible (copy meaning I can hear him send CQ and his call sign). My RX antenna is just a small pennant (51.6% the size of a full size pennant) using one W7IUV preamp, an old Kenwood TS-180s with 500 Hz filter and a 200 Hz hi-per mite active audio filter. A few times we have checked to see if sunrise enhancement would help, but have noticed very little if any sunrise enhancement improvement. There are very rare days where propagation is exceptional (like 12 dB increased signal level compared with a normal day), and all other days signals are just above my noise floor to 6 dB above my noise floor (noise floor not including static crashes from thunder storms). During my summer months the signal level is much less than the static crash peaks, but still able to copy nonetheless. As I said, this is something I would have never thought possible before investing so much test time. Just FYI, Don (wd8dsb) _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
