Hi George,
you are right with 20ms limit, it is also little bit short for complex
system like VHF/UHF EME station or similar "extreme".
But we can use TX INHIBIT if delay is not enough, signal for this can
be genetated by some additional contacts of final relay.
So I suppose there is way not only via TX DELAY.

George napsal(a):
The FAQ for the K3 promised a 0-50 ms amp keying delay. We got only 0-20 ms in the latest
release. I don't think 20 ms is enough in my case, based on my primitive research.
Several "experts" have said mine might need as much as 30-35 ms. My amp's relay is
a 30 yr old Potter & Brumfield open frame model with a 120vac coil.
To make things worse, since the K3 will not switch 120vac, I must use another relay
with a 12vdc coil in the line between the K3 and the amp, which in turn pulls in
the P&B relay. This exacerbates the matter by taking even more time, and I'm
afraid to try anything for fear it will damage the K3 and the amp. Am I wrong??
Anyone care to comment??
One of the many reasons I bought the K3 was to be able to operate at least semi
break in CW and VOX with my old amp without hot switching, by virtue of having
ample switching delay. I've waited months for the feature and am disappointed..
However, I hasten to add this: As a K2 user/owner/builder, I expected much in
the K3. I got much more than I expected. I gave up a nice Icom Pro 3 for the
K3 and don't miss the Pro 3 one iota. The K3 is unbelievable in what it can do
and how superbly it does it. And getting new firmware is icing on the cake.
But I sure wish I had 0-50ms amp delay capability! How about it, Wayne?
