Cinch Jones made sense back when you needed pins to handle 10 or 15 amps
of filament supply and manufacturing couldn't technically or
economically produce some of the connectors we have today. It's an
antiquated connector for things like audio and control lines.
I always thought the Molex connector was one of the cheesiest connectors
around and I would choose binding posts as a standard over these. It's
more a mate-once and forget about it connector. I think the robustness
of a Molex and an APP is about the same (doing the step on in test),
however the genderless nature of APP puts it over the top. APP is now a
standard, period.
Have you used an APP? It's a piece of cake to insert a bare wire into
one of these, either on the mating end or the cable end and on *any*
connector since they have no gender. With a DB-9/15/25 it's easy to
insert a small gauge wire into a female connector (which is what I
believe is used on the K3), and arguably easier to get positive contact
than you will on a slotted Jones female pin.
The soldering argument against the D sub connector is a moot issue. As
I mentioned earlier, cheap prefab cables are available at your local
mall. Even Wally World probably has them. You can even snip the cables
off of dead monitors in the dumpster at the office. It doesn't get much
easier and is in the true scrounger spirit of Amateur Radio.

THEN, you can welcome these toy (D) or non standard (APP) connectors.
What is better, altho old stuff--- Cinch Jones (or even Molex) and
below that, screw terminal strips and/or binding posts. If u r stuck
with only bare wire and MUST make a connection, sticking a bare wire
tip into a Jones socket is DO-ABLE, or even into a Molex.... try that
with D s and even with the APPs.
