heard a great loud signal on 20 a few weeks ago,,,, crystal clear ...
but there was sizzling 10kc down the band....
the scope on the k3 showed it , did not appear big, but I could hear it..
moved to the 7800 and it was indeed there ,,,, still sizziling....
it was Italian ...I did not remember what power he was running,,,,
. maybe he was hitting it too hard???
maybe his amp needed another device to get into the linear region ???
I am no engineer... " but that's just wrong"

not really, that amp has all the stuff, all the filters, the 2 LDMOS rf
pallet is even all tested and biased up. The controller is installed.
You do need to solder some teflon cables. And install some fans and a
rasberry pi. tough stuff.

Doesn't seem like a deal to me.
I'll stick with my SPE 1.3K-FA
(and the new 1.5K-FA when it arrives).
