More investigation is needed as I came to the same calculated power
dissipation for 1.5 dB of loss at 10m. I've validated my measurements on
three separate devices into a Bird Terma-Line load but the QSK-5 does not
appear to run unusually hot at 1KW from an SPE Expert amp. I'll report back
when I find the root cause. Seems like this might be a good use for an
industrial IR-detecting temperature scanner.
