I agree an inhibit pin is a very good idea. One must always remember to
connect it of course. The system needs to fail safe. QSK is not used above
HF as much and a radio that automatically allows a delay is far safer than
one that produces power immediately unless an inhibit line is used. If that

IMHO it all depends on how much development time and valuable flash
memory these enhancements take. The K3 is marketed as an HF rig. I'd
be willing to bet the vast majority of those in service are used as HF
rigs and NOT as a VHF/UHF IF.

Thanks a million for the developers for giving this inhibit possibility.
This makes serious VHF high power applications possible.
Don't remove this option please!!
THANKS

Hi Ian and the group:
I would suggest that you fix/modernize your old amplier and leave the K3 as
is! The problem is NOT with the K3 but rather your amplifier. Upgrade the darn
linear with more modern faster switching relays and vacuum relays are not that
expensive if you shop around for
This is a mots worrying post. I think it demonstrates considerable ignorance
of the many and varied applications of the K3. There is so much more to life
than HF.
How do you suggest we speed up a waveguide relay to 10mS?

If I recall correctly earlier K3's failed the AMTOR -like mode turn
around time from rx to tx and back.
I believe that is about 15 ms. This was apparently fixed. The 10ms
delay between PTT and RF helps it meet this.
So if it is too slow, some group complains. If it is too fast others
Have you tried the inhibit pin (pin 7) of the accessory connector? It will
hold off rf output until set low.
Those serious VHF/UHF/Microwave ops already probably have sequencers. This
can just be a part of the sequencing. See page 19 of the manual.
Early K3's apparently didn't meet the
