Good point Jeff.

I run the VK6 Inwards QSL Bureau and I get quite a few cards for VK6FO, a call that does not exist. However, 4K6FO, is an active DXer on CW.

When I look at the QSO details on the cards for VK6FO and compare them to old spots on the DX cluster/s, I see thay always coincide with 4K6FO's operations.

I have heard 4K6FO on the air and it is true. It sounds like VK6FO, because the first dit is not being transmitted or is so low that it is not easily picked up.

I figured that either he is hot switching his amp or his transmitter is not responding fast enough to that first dit. I don't know which it is.

Modern transceivers have a TX Delay facility, which would probably solve this problem.

I have been noticing in my pileups that I have a hard time copying the first

After listening more carefully, what I seen to find is that the strength of the 
signal as the amps fire up on CW is up to 2 S-units lower than when it gets to 
full power.
Is this the case that amps take a few milliseconds to come up to full power?  
And therefore it may be putting out less than full power on the first few 
letters of a call sign than on latter letters?
