The title was changed to better describe the original question.
This topband newcomer asked what had happened to the topband conditions, given
the rare intercontinental Low Power to Low Power CW QSO’s,
even when riding upon sun propagation enhancements, as noted in this log, during
the last 6 or 7
Hello,
Living in a country, where 10W has been the upper limit set by the regulator in
the early 160m days,
I have been puzzled with this question for a long time...
Given the progress on antenna and Rx-capabilities (over the years) and say
typical transceiver output power (100W),
how come it has
Prior to the CQWW160, we did some (topband) antenna isolation measurements
between:
-a quarterwave inv L (top at 15m down to 11m) and
-a new unterminated beverage (0.8m high) of different lengths (via a 9:1
transformer) and 2 different locations.
