K3 KAT500 'Err AT3' recurring

[Bob KD7YZ]

Howdy K3' people:

I asked this one before. Apparently I never resolved it and I vcan't
make it quit. So am asking again.

Every time I power on the K3, I see the error 'ERR AT3'.

1. There is always power on the KAT500 before the K3 power is on

2. If I 'Tap' the "ATU TUNE" button the VFO-B line is "BYPASS"

3. Tap 'TUNE' button on KAT500 and some very brief clattering then
KAT500 'AUTO' remains green-flashing endlessly until tapped again.

This takes me to another question: When I actually do try to tune a
frequency, I would like to press the "Dash" paddle on the Vibroplex in
the old "Semi" mode where a hold on the Dash-Paddle produces an endless
dash until the Opr lets up on the paddle ... however the Dot paddle
produces endless dots .... my original Vibroplex, which I still have,
was this way as there were no "Keyers" then.

If that's not possible, then how do you hold-the-key-down to adjust for
SWR?

Tapping the old space-paddle very gingerly was my best way of
ever-so-briefly seeing if anything was going to blow-up when I go
key-down.

Reaction time to push a radio "Key" or "XMIT" button is far, far, to
slow to avoid major mishap .. sometimes anyway.

tnx

Bob,

Do you have the KAT3 (the 100 watt tuner) installed in your K3?  I
believe that is the tuner that is being referred to and not the KAT500.

Look at the error codes listed at the back of the K3 manual for initial
troubleshooting actions.
