Bob. I am a broadcast engineer and very capable of measuring ground-wave signals. The FCC does exactly that where issuing citations for pre-dawn AM broadcast stations who are licensed for QRP and actually running QRO. This method has been used for many years. Ground wave measurement lack the variables you speak of. Actually my post was in sorts complimentary to KP4KE's "magic 160 meter antenna" which should in fact if it works this way should be published in the Proceedings of the IEEE, don't you think?

Herb,

Herb,

In order for us to respond to your allegations you will need to provide support evidence. We will need details on his actual antenna configuration, was he using a counterpoise of some sort, is he on a hill, how close is he to the water ? Do you have proof that he was running more than 5 watts ? Comparing his results to your test is meaningless, there are too many variables to consider. You have the burden of proof. Either provide factual evidence to support your allegations or give
KP4KE an apology for potentially damaging his reputation.

Well not to appear to be entirely disputatious we should carefully consider KP4KE CQ WW 160 meter QRP entry in 2005 which he said he accomplished with 4.7 watts to a "magical antenna" which he called a "double bazooka" at 60 feet both for RX and TX. While claiming to work 42 countries with this magical antenna (which is actually a low dipole) in a few hours of operating, I thought I would try and see what 5 watts could actually in fact really do on TB. Using a 1/4 wave vertical and 12 Beverages a few weeks later, and many days after that when the band conditions where hot, I called CQ for 4 hours each night without a single reply. During this contest I recall hearing NP4A and Pedro's great set up running full power, and very high dipole at 200' and the signals were always the same on 160 at my location. So either KP4KE has a "magic antenna" or his "QRP" entry in the CQ WW 160 meter QRP category totally lacked credulity.

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 winter topband contests.
(the last 3 years = topband newcomer)
