KPA500 AUX Cable Keying

Y' All

According to page 21 of the KPA500 owner's manual, when the Aux Cable is used
with the KPA500 the PTT Cable should not be used.

I have the KPAK3AUX cable connected between the K3 And the KPA500 via the Y
cable that came with the cable kit, so that I can continue using my KR2C2.

The KRC2 is working as was before.

I have set all the power levels for the amp Standby and Operate of the KPA500
and I can see that it is controlling the K3's output power in both Standby and
Operate, and is changing bands when the K3 changes bands, but the KPA500 is not
keying when in Operate on any band.

The Amp was keying and producing output as expected with around 30W drive before
I hooked up the AUX cable. I'm sure I've failed to make a setting on the amp or
the rig, but I'll be darned if I can find a setting that even vagely sounds like
the one to make.

Can someone shed some light on what I need to do to get the amp to key with the
Aux Cable connected?

Re: KPA500 AUX Cable Keying

Hi Tom,

Do you have the "Key line interrupter", as described in:

http://www.elecraft.com/manual/KPAK3AUX%20Cable%20Set%20Instructions.pdf

installed? If so, you might try removing it....

Re: KPA500 AUX Cable Keying

Hello Iain,

No it's not in line, but I sure thought of putting it in line so I could use the
key line between the amp and the rig.

The amp and the rig are communicating with each other just fine, but the amp
won't key.

Thanks for the help.

Make sure that DIGOUT1 is turned OFF from the K3. Turning it on disables the KPA. Note that this is a per-band function, so it needs to be turned off for each band you wish to use the KPA500.

I assume that I will be able to use the Y cable with my MicroHam K2?

Update:

This was being caused by the PR6 preamp being installed. It was inhibiting
keying of the KPA500.

All is well now...

Re: KPA500 AUX Cable Keying

The plan for Pin 11 (I understand) is to eventually inhibit the KPA500 when pressing TUNE on the K3 so that you can tune a manal or auto-tuner at low power without having to remember to manually put the KPA500 in standby first. My understanding is that this will be in a future K3 firmware release as a set-up option.

Just for completeness, it's per-band x per-ANT1/ANT2.
