I am having difficulty performing the Bridge Null Adjustment of C55 on page 16 of the manual and could use a little help, if you please.
I am unable to get the ATU CALn measurement of reflected power to be anything but ‘HI’ … in other words, no null. I have checked the SWR bridge components and solder joints; the toroid was wound by Mychael, not me, so I know it is not the culprit … When I go on to check the receive and transmit voltages on U4 pin 1 (page 17) I find 0 volts on receive, which is good, and 4.8 volts on transmit which ain’t too far off from 3-4 …. Should I push on, or am I heading down the path to oblivion (or, at least, the path of improper antenna tuner function)! ------------------------------------------------------------------------------- This email message, including any attachments, is for the sole use of the intended recipient(s) and may contain information that is proprietary, confidential, and exempt from disclosure under applicable law.
