Hi All
I just wanted to put on record my thanks to all those who offered advice and
support as I worked through the issue with my KRX3A.
It’s all working now. For the record, I think it was a poor connection caused
by one of the TMP cables not being engaged fully.

It seems to have been a transient. Signals appear to be comparable this morning.
This is all by ear of course.

Glad to hear you got it working. But you shouldn’t be seeing a signifiant
difference between the two receivers, unless something is set differently
between them, or there’s another issue floating around.

Well, I’ve solved the initial problem. I stripped the rig back to its pre-KRX3A
state and then re-installed: after checking performance.
I can only surmise that there was a poor connection somewhere, as basically all
I did was re-installed some TMP cables.
The performance of the SUB is poorer t

Yes, and I had the receptacle for a TMP cable come unsoldered from the
circuit board in one of my K3s.

Make sure the TMP connector center section on the boards is not broken or
push out. Easy to do if the TMP tip not lined up into the connector.
Also make sure that the pins from the SUB to the RF board are not missed
aligned.

Thanks, Ben
I'm going to open her up again and do another check on the seating of the KRX3:
it's quite difficult to be sure both the multi-way connectors are properly
mated. I'm also going to check continuity on all the leads.

Ref pp 43 of KRX3 Istallation and User Guide Rev F Dec 22 2010
ALWAYS Set ANT = BNC if not connected to KAT3.
Clarification:I believe config selection ANT=ATU may be inserting
attenuation during transmit in the KRX3 signal path to provide protection.
Make sure KSYN3 tmp connections good.
Only had a K3 w/out the KAT3, I’m not sure. But if Sub ant is bnc the you need
to connect its ant to the bnc Aux port I think.

Hi, Gareth.
Well...you certainly have a mystery here. I found the documentation in the
Elecraft manual on this subject a little hard to follow; the book by Fred Cady
on the K3 is better and, if you'd don't have have it, I highly recommend it.

As I said in the OP, this was a rig bought secondhand.

I’m going to open the rig up and check that it’s installed properly first. Then
it will be time to contact support.

I tried that, Richard.
ANT definitely says MAIN but still no signal.

There is no ATU, so there is only the one ANT to select. However, I have
checked that CONFIG KRX3 has Ant=ATu (even though there is no ATU, only this or
BNC are offered as options)

Gareth,
You probably don't have the correct antenna port assigned to the sub
receiver. I'm not in front of my rig, but I believe you need to push
and hold A/B (B Set) to get to the sub receiver, at that point be sure
the correct antenna port is selected.

Hi there
I bought a s/h K3S a couple of years ago (SN 10901). It has a KRX3A installed,
but I’ve never tried to use it until now. When I enabled the sub receiver this
morning, I found I was getting no signal.
I’ve checked various CONFIG settings and it’s set to use the MAIN ANT and it’s
