Kenwood / KPA500 cable

[ANDY DURBIN]

What cable is Elecraft selling for interfacing the Kenwood TS-890S or TS-590SG with the KPA500.  Can someone point me to a cable drawing?   A post to TS-890S group seems to suggest that Elecraft is selling a cable that does not support active low solid state keying for these rigs.

Thanks and 73,
Andy, k3wyc

Hi Andy,

I have no idea what they're selling, but all you need is coax for RF and
a cable to connect the rig's Amp Key out to an RCA on the KPA500. 
That's all I've ever used. Elecraft amps and tuners all detect RF
frequency near instantaneously, and switch to the right band.

Hi Jim,

I know you, and probably many others, are content to use RF frequency detection but it did not appeal to me.  In fact I disliked it so much that I have invested a lot of effort in creating a controller that configures my KAT500 and KPA500 before any RF is emitted. (It does a lot of other things too)

I don't have a TS-890S, just the much more humble cousin the TS-590S.  My only interest in the cable was to help a TS-890S owner.  The configuration of the keying cable is independent of whether RF detection is used or not.   A proper cable for the TS-590SG and TS-890S would use the active low solid state output of the rig, not the relay output (Especially true since Elecraft take great pride in silent keying).

73,

I'm a huge fan of KISS when it's just as good as complicated. :) And
Elecraft's implementation is VERY good.
