[Elecraft] Extra Protection For KPA500? AUX CABLE SET??

Sun Mar 8 17:08:14 EDT 2020

Not getting any answers from Elecraft.com...still thinking about getting new cables that aren't as thick as a garden hose!

KPAK3AUXSE Enhanced Mode. Aux Cable Set + second E850463 Aux Cable
Enhanced Mode. Aux Cable set for KPA500 AND second E850463 aux cable for KAT500. AUX Cable Set incl: 15-Pin to 15-Pin DE-15 + Key Line Interrupter adapter

So does the Aux Cable Set include two E850463 cables for $50 or only one E850463 and the key line interrupter?

And to get two E850463 cables, you have to order two E850463 cables at $30 each?

One other thing to consider is that you don’t want to connect all of the pins straight through from the K3 to the KPA500. There are some conflicts that will cause problems. The Elecraft cables are set up properly with the appropriate pins cut that should not connect between the two devices. An alternative is to use a straight-through HD15-HD15 cable with the appropriate pins cut. Cutting them yourself is a pain, so we really don’t recommend that route.

Then with the KPA500 on and in OPER mode, while in RX, set the PWR value on the K3S to 20 watts or what ever power you wish to drive the amp with for that band. That is saved for that mode and band.   Then on to the next band.

When the KPA500 is switched to OPER then the power value is what you have set for that mode and band.   This does require the KPA500 to communicate with the AUX cable.   See page 12 Fig 3 of the KPA500 manual for the configuration.
