I've had a habit of reducing my power to 2W when tuning. I've noticed for a long time that the SWR indication at minimum when tuning my remote T1 never went below 1.2:1. No big deal but always made me wonder what was going on.
A few minutes ago I was playing with the ATU functions again with a 50ohm dummy load and the ATU always made it to 1:1. Yet when I went to bypass I again got 1.2:1. Then I remembered that the ATU always tunes at a preset of 5W. I changed my TUN PWR when in bypass to 5W and got 1:1 after all. It seems from this that the SWR bridge and its a/d conversion must be calibrated only at (or above) 5W. Is that correct? 73 jim ab3cv _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list. Subscriber Info (Addr.
