I looked at the archives of the muscle car reflector. Mustang GTs
suffer from blown engines, bad spider gears in the rear ends, blown
transmissions, and occasional splits in two when they hit trees.
I'm amazed Ford has never fixed the problems,

Depends on the blower. For high power RTTY work, a high speed
blower is required. The original blower was downsized in 1988 to
reduce complaints about noise.

That was resolved years ago, around the mid-90's. The problem
was poor grounding of the cathode at the third harmonic of ten
meters. Changing the input cable to the tube deck cleared most of
that up.

What parasitic problems? Can you tell me how to identify them?

Woops. I guess it needs a smaller blower still. Well, there goes the
CW duty cycle!

Yep, that's true.

Same with Mustangs. I'm amazed Ford sells any. From looking at
complaint lists, everything is wrong with them!

One reason you can't find an amp that fits you needs, is that the
market doesn't demand one. Another is demands often argue
against themselves.
