Hello K3 owners.
I need to replace U1 on the KIO3 board.
In my K3 sn: 218x the part nr is: SN75C1406 G4.
Is there any other SN75C1406 can be replaced with the ''old one''.
Thanks in advance :-)

It doesn't matter how many "sound cards" are in the system. What does matter
is that the one assigned to digital modes is not also assigned as the system
"default" device. It is easy to get this wrong even when two or more "sound
cards" are available.
I think you guys may be assuming
I have a second sound card in my desktop PC dedicated to the digital modes. I
thought the risk of inadvertent audio driving my rig was too high to do
otherwise.
I’ve heard some weird things on the digital frequencies!

I politely and firmly, disagree. It's too prone to operator error and
sending cruft that doesn't belong on the air.
A SECOND internal card for radio, fine. The only one; bad plan.

And ranks right up there with folks using the
CAT allows true rig split or "fake it" modes of WSJT-X. In either case the
modulation frequency is limited to the range 1,500 to 2,000 Hz and any audio
harmonics fall outside the TX passband of most transceivers. CAT and the
WSJT-X split modes do not prevent generation of audio harmonics but
Hi,
I had the exact same issue, with the exact same symptoms, sent it into
Elecraft, got it back, and it worked until I sold it.

Thanks Alan,
I'll take a look-see this weekend and see if it's something I can
tackle.
I've recently dealt with tiny flex connectors like that on another
project,
and it survived. :-)
I'll be sure to come back here and report my findings.

Hi Dave,
Another possibility is that perhaps one of the display connectors has
come loose or is making a bad connection.
I normally wouldn't recommend this since these tiny connectors are kind
of tricky, but since the P3 isn't working anyway, there's nothing to lose.
There are two

Mike,
Thanks for the idea! I hadn't considered that mitigation.
Anyone else have ideas for a permanent corrective action?

Well my 10+ yr old P3 seems to have finally bit the dust.
I had been having issues with getting the internal display to turn on
when powering the P3 up.
I had found that by letting it run for a minute or so (the external
display always worked), that I could then quickly cycle the power
