Topband: QSX in the tropics

When I put Senegal on 160 for the first time ever in November 1967, my h.b. 40-watter was heard well from a semivertical half wave on Cape Verde. But only a few big guns made it into the log thru a constant gigantic QRN level. In those times, only several signals could be noticed at the same time, a far cry from the huge pile-ups nowadays.
The ITCZ (intertropical convergency zone) lags the Sun's declination by about three months. So it is presently at its  northerly position and looks like a defective neon as viewed from an airplane.This makes things most difficult for the C52C boys yet they show a nearly incredible receiving performance.
Kudos to all "tropical" operators/DXpeditioneers for their ability, patience and perseverance!!!
Shame on the authors of more than inappropriate comments ("deaf", "no rx", etc.) in this context. Their comments fall back on them.
