KPA-500 Issues

I have the combo K3S/KAT500/KPA500 with all of the optional interconnection cables.

I am not able to key the amp though it was working earlier. The asterisk does not appear in the display.

I went through the menu and everything is set accordingly. The inhibit is disabled.

Any help would be appreciated.

73,
Ed NI6S

That implies that the AUX cable is not working. Cycle the gear power
and make sure each connector is properly seated.

In reply to this post by Elecraft mailing list

Check the cable connections, including making sure that none of the pins are bent in the AuxIO connectors in both cables (K3S - KAT500, KAT500 - KPA500).
Also, make sure that the PTT line is actually being asserted. The asterisk is displayed when the Key In is asserted. If it isn’t displayed that means the KPA is not seeing that input active. Also realize that when the KAT500 is in tune mode it blocks the key line going to the KPA.

It is fairly common for someone to move something and the cable comes loose. Be sure the screws are tightened down on the connectors and any adapters to avoid this.

Re: KPA-500 Issues

What is the SWR? If above the KAT500 set value it inhibits the amp from being keyed. Check the KAT500 using the ATU utility.
