K3/KPA500/KAT500 revs 4.83/1.38/1.58

All working smoothly except:

On a couple occasions, after manually initiating a tune, the tune completed
satisfactorily and then the KPA500 indicated a fault right at the end of
the tune cycle. Pretty sure it was a soft fault but I habitually hit the
button to clear it ... will observe more carefully if it happens again.

73, Carl WS7L

Re: K3/KPA500/KAT500 revs 4.83/1.38/1.58

Oh yes, I remember now yesterday I got a soft fault on the KPA500. I turned on the K3, the KAT500 went to the pretuned setting on 40M and then I turned on the KPA500 and clicked it into operate.
I said one word and the KPA500 went to standby. No red lights. I returned it to operate and everything worked well. Forgot about that...not a problem, but don't know why it did that.

Chuck,

I seem to remember reading that the order of turning on the K-line is
important. I always turn on the KAT500, then the KPA500 followed by the
K3/P3. I have not had any issues doing things in that order. Maybe this
is why you had the 'problem'?

Re: K3/KPA500/KAT500 revs 4.83/1.38/1.58

The KAT500 needs to be powered on whenever the K3 is on in order to avoid loading the Auxbus. It can be powered up at the same time, but must be on before the K3 completes its initialization.

The KPA500 has no restriction, and can be powered on any time before or after the K3 is turned on.

Sounds great but most of the time my KAT500 won't turn on until I turn on the K3.

What now?

Re: K3/KPA500/KAT500 revs 4.83/1.38/1.58

You might want to say how you have the KAT powered. In my station I have a relay-switch power panel that I built. The relay is powered by the K3’s 12V output jack. When the K3 turns on, it powers the relay, which the switches 12V power to the various station boxes, including the KAT500. By the time the K3 is ready to talk to the KAT, it is awake and listening, as is the KRC2, P3, etc...

Check the KAT500 configuration Initial Power screen to see if Power On When DC Power Applied is checked.

Yes,
The KAT500 needed to be powered first. I also used to do that. That was
in the 'older firmware times'.

With the current FW, up till now I never bumped into any issue no
matter which device was turned on first.

My KAT goes on with the bench power supply. Then I turn on the K3 and the the KPA.

Re: K3/KPA500/KAT500 revs 4.83/1.38/1.58

In reply to this post by Arie Kleingeld PA3A-2

Here is how to make it fail:
Disconnect the power completely from the KAT500 (maybe the micro in it stays on when it is "powered" off).
Turn off the K3 with its power switch with the KPA turned on.
Turn on the K3 with the KPA500 on.
I get either a blank K3 LCD display or it is hung up.

To recover:
Turn the power supply to the k3 off.
Plug in the power cable to the KAT500 (I use the same supply as the K3 with a Rig runner that powers everything up at once when the K3 turns on).
Turn the K3 and KAT500 power supply on.
Hit the Power On button on the K3.

YMMV.

Well that must be the result of what Jack said about loading the aux buss if the KAT is off when you turn on the K3.

Re: K3/KPA500/KAT500 revs 4.83/1.38/1.58

In reply to this post by Carl Clawson-3

I think I found a little thing to improve.
the KAT500 can miss a frequency update from the K3 in a certain situation

To replicate:
- Switch everything on and operate the KAT/KPA/K3 combo as usual with
KAT500 in manual mode
- Activate the KAT500 utility for monitoring the KAT500 and select the
Operate tab, here you can see the last observed frequency. See that
KAT500 follows theK3 freq and switches accordingly.

Now....
- set the KAT to BYPass
- Change K3 freq, note that the KAT500 freq info does not follow this.
- Switch KAT to MANual, note that the freq info is still not there
- now transmit with the K3, note that the KAT detects the frequency now
and switches to the appropriate setting (the old way).

Improvement = KAT500 follows K3 freq in all KAT modes. so also in
BYPass, and switches to the right setting as soon as you switch to
MANual or AUTO.
