Herb,
It does sound incredulous, to say the least.
But even ground-wave signals can be subject to reflections and attenuations and
cancellations and additions such that it's not completely outside the bounds of
reality, given the different path lengths between Christiansted and Aguadilla
and between Christiansted and Ponce.
While I understand, and probably share, your suspicions, the only way to know
for certain is to have a trusted operator verify KP4KE's power level and then
attempt to recreate the performance at a known 4.7 watts. Perhaps that requires
disconnecting all power sources to the station and using just a battery, with
an ammeter, to eliminate the possibility of a hidden amplifier.
If KP4KE is willing to allow such a test, doesn't that buy him at least open
minds on our part?
Given your own observations, and given the probability of recreating the
conditions that led to your observations, perhaps yours is the best station to
be the receiving station? Wouldn't you relish the chance to be proven right,
even if it comes with the chance of being proven wrong? Would you be willing to
suspend disbelief long enough to have an open mind?
Anything less than a trustworthy experiment is just speculation.
I share your suspicion, but suspicion is not proof. That it appears KP4KE is
willing to try is, to say the least, intriguing. What's the harm in trying?
73, Kelly
