The KPA100 and KAT100 depend on internal signals from the base K2.
So the answer is NO - the KPA100 and KAT100 can only be used with the K2.

You can use DATA-A to do LSB too. I do this when I set up the KX3 for packet
radio, because it places the LO just nicely so I can also monitor the local CW

The tuning range of the KXAT1 will b limited on 80 meters, so your
antenna configuration will be more critical - I recommend an 80 meter
antenna that is close to resonance.
An end fed antenna suspended from a tree or a hotel balcony is not
likely to do the job on 80 meters simply because

If your fuseholders are of the 3AG type, consider replacing them with

In your case, there are two things to check - the T/R switching and the

The receiver muting is the easiest - is Q10 working is the question. If

Jan,
Check your antenna selections - ANT1 vs. ANT2 or RX ANT on vs. off.
The amount of attenuation you hear is about the same as the isolation
between the antenna selection in the K3 (40 to 50 dB).
The antenna selection is on a per band basis.

Yes, a shorted Q10 will cause the audio to be muted all the time.
The K1 will operate without Q10 installed, so that is your first
troubleshooting tactic. However, without Q10, the receive audio will
not mute when in transmit - just something to be aware of when
evaluating the effects.
The decision was easy for me: My shack desk is too small to add a P3,

No, the KPA100/KAT100 only works with K2. For a solution that works with
