Hi,

If the Ducie and Clipperton island expeditions were used to judge the
transmit audio quality of the K3 (Ducie) and the Pro III, K3 would emerge as
a clear winner. TX5C audio varies from fair to poor, often muddled with no
highs at all. Once when they changed operator, the audio immediately went
from fair to poor, so I assume that they use their own boomsets. I wonder
how they are doing, the storms last night seemed to have unsettled them a
bit. I see them on the cluster on 80 and 40 this morning, so I guess they
are OK.
