I see. The real issue is amplifier turn on timing. As I don't use an amplifier as QRO to me is a 100 Watts. I can't address the issue from experience. However, I suspect that there is an easy fix since all high power users face the same issue, particularly on CW. Someone needs to check to see is there is a delay built in to the PTT function the allows the amplifier to turn on when the PTT is keyed in proper sequence. I know this is not an issue with my Orion II, and I infer from those who do operate at the full legal limit around my neighborhood that this issue is a non-issue; a lot of them are using FT-1000s and K3s
After mulling this over as I write this response, I come away with the idea that a parameter in the transmitter keying menu has not been changed to account for the amplifier turn on delay. Someone should check that. 73, Barry K3NDM On 7/27/2012 9:03 PM, Lance Collister, W7GJ wrote: > As usual, Joe is RIGHT ON THE MONEY!
