Bob,
A question about your statement that you run 400w in digital modes
(assuming you mean FT8, etc. and not RTTY). That seems pretty extreme.
I pretty much ignore HF usage as I am not on HF very much (primarily
an eme'er on 6m+). But back at the beginnings of psk-31 I built a HB
interface* for my FT-847 and did a bit of 14.070 operating (with a
dipole). I was recommended to not exceeding 25w (or 25% full
power). Everyone seemed to do quite well on psk-31 with low power
and some ran at QRP (<5w).
I do not get why I hear of running high power digital when 10% would
communicate easily. You may remonstrate me for running 2m-eme at
1500w on JT-65 but the path loss on 2m-eme is 254 dB+ and contacts
are made over a half-million mile path. Certainly not encountered by
terrestrial HF users.
Not picking on you personally, but you made the statement so figure
maybe would reply. Just curious.

* that I/F later was used for JT-65 on eme 15 years ago. Now use my
K3 directly connected.

I do run 400 watts or so on digital modes. Issues are not really
noted on SSB or CW modes.
I've set the Fan Ctr to 2 and 3 and still noted the issue
Was recently showing my K Line to some hams friends. They commented
rather negatively on the point.
