Am I over looking something? Can't the cable be routed,
then the connectors installed? Might make a neater
installation, avoiding coils of excess cable....or cables
which might be too short.

No, you're not overlooking. But it just feels plain stupid to first cut the
plugs, route the cables and then reassemble them. What would you like to do
most: solder a plug with tiny contacts or just strip the wire, crimp on a
pin and screw them into a screw terminal?

And believe me, it's not just theory but this is backed up with
measurements: a 4800 baud signal is just not going to produce interference
because the last inch is not screened and connected to screw terminals. They
are physically too small to be able to radiate enough energy to interfere
with an SSB.

Yep, soldering tiny pins is no fun. I agree 100% that 'strip n crimp'
is the way to go. When I was doing embedded controllers for
ag equipment, I used 3M plastic circular mating connectors. They had the
advantage of strain relief and some protection from dust and moisture,
to say nothing of accidential shorting.

As to 4800 baud radiating for 1 inch unshielded...not much chance of that.
The only exception might be if the rise time of the pulses was quick
enough...often seen in switching power supplies....to cause the old
'comb' of harmonics.
