I just received a pre-owned MFJ-998 and have a couple of questions. When I first powered it up I had it run a self diagnostic and it came back with a "Wakeup Fail" fault. I had to walk away for a while to deal with something else, came back an hour or so later and re-ran the self diagnostic and this time everything was fine. Since then I've had it match all my antennas across the respective bands and it seems to be working perfectly. SO...... does anyone have any suggestions as to what that "Wakeup Fault" alarm was all about? I've been searching but so far haven't found a good answer. ALSO, how do those of you with MFJ-998s use them in conjunction with an amp? Full Auto mode? Semi Auto? I have an FT-920 and an AL-811H amp and yes, I have the amp keying line wired through the MFJ-998. Do you simply press 'Tune" when you change frequencies by a certain amount (in conjunction with sending it RF)? Turn the drive down to below 30 watts and then press "Tune"? I'm just trying to figure out in my mind the best compromise between convenience and being kind to the radio and amp.
