I'd take good old Jones Plugs any day over APP's, for all factors, current
rating, ease of use, reliability, cost AND re-usability.
Soldered connections (no crimps) and they have simple locking ears that are
easier to use than the Molex squeezer.
But then again, I'm a dinosaur wishing for a situation that will never be
(kinda like our country now).

Jeff,
I am not sure what your circumstances are, but I have found that the APP
connectors are more durable than the Molex connectors typically used by
the YakIcKenwood gear.
Perhaps you do not have any slack in the cables, and any movement of
either the cable or the gear will create a force sufficient to separate
the connector. A bit of slack in the cable should prevent that condition.

Hi Don,
Thanks for the reply but I'm talking about Elecraft factory installed
APP's both in the radio and on the cable.
I have also made my own cables using genuine and non-genuine APP's and
they are exactly the same, they will NOT stay together under actual
portable operating conditions.
Upon inspection through a magnifying glass all connectors I have here are
indeed assembled correctly and this is the SECOND K3 I've with similar
issues. (The first radio I had owned from new (#4257))
In the case of my first K3 it would overheat the connectors that were
soldered into the PCB!
Granted it had an issue with extremely poor soldering of the connectors
but the fact remains that on that radio and the one I presently own, the
APP's are not up to snuff.
They just do not grip each other well enough to cope with the rigours of
operating portable in the bush and other adverse environments.
Hence my desire to change out the APP's and go for something that is
considerably tougher.
I've also had a few emails off the list so far that are also detailing
similar issues and doubts with APP's and I have no doubt that I will be
getting more.
I guess that I've found the reason why APP's are not an approved
connector for any emergency gear by any emergency authority in any
country as they are just too unreliable.
As I live in an area that regularly gets cyclones (hurricanes) and
flooding each year I want be be able to rely on my gear in case of an
emergency as well as my normal day to day operations, therefore I really
want to ditch these unreliable connectors and get something decent
installed.
So my question stands, what are my alternatives?
