For SSB op's only, T/R delay K2

[info4mjs]

I've been discussing the following issue off line and I wanted to know if I am imagining a problem.  I have set the SSB mode to PTT and have adjusted the T/R delay to be 0...which means I should have virtually no delay from when I release the PTT switch until the time I hear audio.  Well, I have a delay in the neighborhood of a couple of hundred milli-seconds.  I confirmed that the VOX modes work and that the delay is adjustable so I was wondering....

When you release the PTT switch, do you hear audio instantly or is there a small delay.  As a comparison, there is virtually no delay when I use my ICOM radio.

Thanks for any insight.

On S/N 1641 there is no perceptable delay whatsoever. Perhaps you might
want to check stuff in the AGC section?

Or if a big capacitor is misplaced somewhere in T/R circiut !
Something must cause a TX hang time.
