Don,

I suspect that Tom wants to run in CW+ (or QRQ) mode, and I believe in this
mode the TX DLY delay parameter must remain at "8" and this effectively
produces a delay from KEY IN to KEY OUT on the order of 4 to 5 msecs.   I
also believe it can not be increased by changing TX DLY?  

My guess is the vacuum relays in the amp might not switch quite this fast.

73,
Chuck, W5UXH
